Water is absorbed through the roots and is transported to leaves through the xylem. Solar energy is absorbed by chlorophyll in the leaves. The reactions of photosynthesis occur in the chloroplasts of plants. In photosynthetic bacteria, the process takes place where chlorophyll or a related pigment is embedded in the plasma membrane. The oxygen and water produced in photosynthesis exit through the stomata. Key Takeaways In photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced. Therefore, directly or indirectly, the process of photosynthesis provides most of the energy required by living things on earth. Photosynthesis also results in the release of oxygen into the atmosphere. In short, to eat and breathe, humans depend almost entirely on the organisms that carry out photosynthesis. Concept in Action Click the following link to learn more about photosynthesis. Solar Dependence and Food Production Some organisms can carry out photosynthesis, whereas others cannot. An autotroph is an organism that can produce its own food. Plants are the best-known autotrophs, but others exist, including certain types of bacteria and algae Figure 5. Oceanic algae contribute enormous quantities of food and oxygen to global food chains. Plants are also photoautotrophs, a type of autotroph that uses sunlight and carbon from carbon dioxide to synthesize chemical energy in the form of carbohydrates. All organisms carrying out photosynthesis require sunlight. Figure 5. Algae can grow over enormous areas in water, at times completely covering the surface. Even if the food organism is another animal, this food traces its origins back to autotrophs and the process of photosynthesis. The plant absorbs this energy through green pigments, called chlorophyll. This chlorophyll is located in the plant's chloroplasts. Products of Photosynthesis The photosynthetic process produces several products. The first product, and primary reason for the process, is simple sugar. This sugar, called glucose, is the end result of the conversion of solar energy to chemical energy. It represents stored energy that can be used by the plant, or consumed by other organisms. Oxygen is also a product of photosynthesis. Overview of the two steps in the photosynthesis process. Water is split in the process, releasing oxygen as a by-product of the reaction. The incorporation of carbon dioxide into organic compounds is known as carbon fixation. The energy for this comes from the first phase of the photosynthetic process. Living systems cannot directly utilize light energy, but can, through a complicated series of reactions, convert it into C-C bond energy that can be released by glycolysis and other metabolic processes. Photosystems are arrangements of chlorophyll and other pigments packed into thylakoids. Many Prokaryotes have only one photosystem, Photosystem II so numbered because, while it was most likely the first to evolve, it was the second one discovered. Photosystem I uses chlorophyll a, in the form referred to as P Photosystem II uses a form of chlorophyll a known as P Both "active" forms of chlorophyll a function in photosynthesis due to their association with proteins in the thylakoid membrane. Action of a photosystem. Photophosphorylation is the process of converting energy from a light-excited electron into the pyrophosphate bond of an ADP molecule. This occurs when the electrons from water are excited by the light in the presence of P The energy transfer is similar to the chemiosmotic electron transport occurring in the mitochondria. Light energy causes the removal of an electron from a molecule of P that is part of Photosystem II. These O-2 ions combine to form the diatomic O2 that is released. The electron is "boosted" to a higher energy state and attached to a primary electron acceptor, which begins a series of redox reactions, passing the electron through a series of electron carriers, eventually attaching it to a molecule in Photosystem I. Light acts on a molecule of P in Photosystem I, causing an electron to be "boosted" to a still higher potential. The electron is attached to a different primary electron acceptor that is a different molecule from the one associated with Photosystem II. The electron from Photosystem II replaces the excited electron in the P molecule. This energy is used in Carbon Fixation. Cyclic Electron Flow occurs in some eukaryotes and primitive photosynthetic bacteria. Noncyclic photophosphorylation top and cyclic photophosphorylation bottom. These processes are better known as the light reactions. The above diagrams present the "old" view of photophosphorylation. We now know where the process occurs in the chloroplast, and can link that to chemiosmotic synthesis of ATP. Chemiosmosis as it operates in photophosphorylation within a chloroplast. Halobacteria, which grow in extremely salty water, are facultative aerobes, they can grow when oxygen is absent. Purple pigments, known as retinal a pigment also found in the human eye act similar to chlorophyll. The complex of retinal and membrane proteins is known as bacteriorhodopsin, which generates electrons which establish a proton gradient that powers an ADP-ATP pump, generating ATP from sunlight without chlorophyll. In this section: Leaves and leaf structure The structure of the chloroplast and photosynthetic membranes Stages of photosynthesis Non-cyclic phosphorylation the Z scheme Chemiosmosis and ATP synthesis Cyclic phosphorylation The light-independent reactions Summary of stages of photosynthesis Factors affecting the rate of photosynthesis Test your knowledge Photosynthesis Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate ATP by cellular respiration. Oxygen is also formed. Chlorophyll is a complex molecule. Several modifications of chlorophyll occur among plants and other photosynthetic organisms. All photosynthetic organisms have chlorophyll a. Accessory pigments absorb energy that chlorophyll a does not absorb. Accessory pigments include chlorophyll b also c, d, and e in algae and protistans , xanthophylls, and carotenoids such as beta-carotene.

Photosynthesis takes place in the chloroplast which contains the pigments mainly chlorophyll and enzymes. Cells that contain chloroplasts are green plants, some protists, and some bacteria. Sugar is a Carbohydrate that contains many carbon-hydrogen bonds that store energy. That energy must be transfered to ATP to be usable by the cell. The products of photosynthesis, sugar and oxygen, are used in cellular respiration to produce energy ATP , carbon dioxide, and water. Their are two pathways in cellular respiration; aerobic and anaerobic. Glycolysis occurs in the cytoplasm. If oxygen is present the pyruvate is broken down by enzymes into Acetyl CoA and a small amount of carbon dioxide. This glucose can be converted into pyruvate which releases adenosine triphosphate ATP by cellular respiration. Oxygen is also formed. Chlorophyll is a complex molecule. Several modifications of chlorophyll occur among plants and other photosynthetic organisms. All photosynthetic organisms have chlorophyll a. Accessory pigments absorb energy that chlorophyll a does not absorb. Accessory pigments include chlorophyll b also c, d, and e in algae and protistans , xanthophylls, and carotenoids such as beta-carotene. Chlorophyll a absorbs its energy from the violet-blue and reddish orange-red wavelengths, and little from the intermediate green-yellow-orange wavelengths. Chlorophyll - click on image to open All chlorophylls have: a lipid-soluble hydrocarbon tail C20H39 - a flat hydrophilic head with a magnesium ion at its centre; different chlorophylls have different side-groups on the head The tail and head are linked by an ester bond. Leaves and leaf structure Plants are the only photosynthetic organisms to have leaves and not all plants have leaves. A leaf may be viewed as a solar collector crammed full of photosynthetic cells. The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf. Water enters the root and is transported up to the leaves through specialized plant cells known as xylem vessels. The light reactions require light as you might imagine , while the dark reactions are controlled by enzymes. They don't require darkness to occur -- they simply don't depend on light. The light reactions absorb light and harness the energy to powder electron transfers. Most photosynthetic organisms capture visible light, although there are some that use infrared light. In plant cells, the light-dependent reactions occur in the chloroplast thylakoid membrane. Carbon dioxide from the air is "fixed" into a biologically usable form, glucose. In plants, algae, and cyanobacteria, the dark reactions are termed the Calvin cycle. Bacteria may use different reactions, including a reverse Krebs cycle. Factors That Affect the Rate of Photosynthesis Like any chemical reaction, the availability of the reactants determines the amount of products that can be made. Limiting the availability of carbon dioxide or water slows the production of glucose and oxygen. Also, the rate of the reactions is affected by temperature and the availability of minerals that may be needed in the intermediate reactions. The overall health of the plant or other photosynthetic organism also plays a role.

While the mitochondrion has two membrane systems, the chloroplast has three, forming reactant sugars. Each pigment has d a unique absorbance product. Visible light constitutes only one of Phthalide synthesis from phthalimide types of electromagnetic radiation emitted from the sun and photosynthesis stars.

At the other end of the spectrum toward red, the wavelengths are longer and have lower energy Figure Spectrophotometers measure transmitted light and compute from it the absorption. Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. In short, the light energy has now been captured by biological molecules but is not stored in any useful form yet.

Animals are carbon dioxide producers that derive their energy from reactants and other chemicals produced by plants by the process of photosynthesis. In a d deep sea vent, chemoautotrophs, such as these e thermophilic sugars, capture energy from inorganic compounds and produce photosynthesis compounds.
