Photorespiration Simplified photorespiration and Calvin cycle. Photorespiration (also known as the oxidative photosynthetic carbon cycle, or C2 photosynthesis) is a process in plant metabolism which attempts to reduce the consequences of a wasteful oxygenation reaction by the enzyme RuBisCO.

- Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek φῶς, phōs, light, and σύνθεσις, synthesis, putting together. In most cases, oxygen is also released as a waste product. Most plants ...

What is photosynthesis? Photosynthesis (photo = light and synthesis = to make) is the process plants use to change carbon dioxide and water into sugar using sunlight.This sugar, glucose, is their food, and the process gives off oxygen. Photosynthesis is the conversion of light energy into chemical energy by living organisms.The raw materials are carbon dioxide and water. The energy source is sunlight, and the end-products include glucose and oxygen. It is arguably the most important biochemical pathway, since nearly all life depends on it.his sugar, glucose, is their food, and the process gives off oxygen. Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water. The energy source is sunlight, and the end-products include glucose and oxygen.

What is photosynthesis? Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the fuel used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll.

- Phototroph. Definition. noun, plural: phototrophs. An organism, typically a plant, obtaining energy from sunlight as its source of energy to convert inorganic materials into organic materials for use in cellular functions such as biosynthesis and respiration.upplement. In order to capture light as source of energy, photoautotrophs carry out photosynthesis, converting energy from sunlight, carbon dioxide and water into organic materials. Photoautotrophs provide nutrition for many forms of life. They include the plants, algae and certain bacteria.

What is Respiration? - Definition, Process & Equation Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP, the currency of energy in cells.alance With Photosynthesis. Respiration is the antithesis to the process of photosynthesis, in which carbon dioxide and water are taken in by autotrophs, along with sunlight, to make glucose and oxygen. Autotrophs include any photosynthesizing organisms, such as plants and algae, all of whom also undergo respiration.

Cellular Respiration Definition - What does Cellular Respiration mean? Cellular respiration is a series of metabolic reactions that occur within the cells of organisms (both plants and animals) to convert biochemical energy derived from nutrients to adenosine triphosphate (ATP) and then release waste products.

Photochemical reaction Photochemical reaction. Written By: Photochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules’ absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules.

- Because in photosynthesis carbon dioxide is taken in, and in photorespiration carbon dioxide is given off, these two processes work against each other. The end result is that photorespiration decreases the net amount of carbon dioxide which is converted into sugars by a photosynthesizing plant. By interfering with photosynthesis in this way, photorespiration may significantly limit the growth rate of some plants.

Photosynthesis - Chapter 7 photorespiration. In a plant cell, the breakdown of a two-carbon compound produced by the Calvin cycle. The Calvin cycle produces the two-carbon compound, instead of its usual three-carbon product G3P, when leaf cells fix O2, instead of CO2. Photorespiration produces no sugar molecules or ATP.

Definition of Plant Respiration Definition of Plant Respiration By Henri Bauholz; Updated April 24, 2017 Plant respiration is the opposite of photosynthesis, which is a biological process performed by green plants that creates oxygen and releases it into the air. During respiration, plants absorb free molecules of oxygen (O2) and use them to create water, carbon dioxide, and energy, which helps the plant grow. Chemical Equation for Plant Respiration The chemical formula for plant respiration is C6H12O6 + 6 O2 => 6 CO2 + 6 H2O + Energy.

Photosynthesis without Sunlight Posted October 21, 2005. Photosynthesis is the biochemical process in which energy from sunlight is converted by plants, algae, and some bacteria into sugars, which are used by the organism as food. That is, these organisms convert the energy of the sun into a different form of energy.
