How one should explain Photorespiration?

Photorespiration (also known as the oxidative photosynthetic carbon cycle, or C2 photosynthesis) refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis. Photorespiration also incurs a direct cost of one ATP and one NAD(P)H.

What is Photorespiration simple?

Photorespiration, or “‘photo-respiration'”, is a process in plant metabolism. A sugar has oxygen added to it by the enzyme (RuBisCO), instead of carbon dioxide during normal photosynthesis. Photorespiration produces no ATP and leads to a net loss of carbon and nitrogen (as ammonia), slowing plant growth.

What is Photorespiration definition biology?

Definition of photorespiration : a light-dependent process in some plants resulting in the oxidation of glycolic acid and release of carbon dioxide that under some environmental conditions (such as high temperature) tends to inhibit photosynthesis.

What is Photorespiration and where does it occur?

photorespiration A light-activated type of respiration that occurs in the chloroplasts of many plants. It is a process that is wasteful of both carbon dioxide and energy, and those plants in which it occurs have high carbon dioxide compensation points. …

What is photorespiration Class 11?

Photorespiration is a process that lowers the efficiency of photosynthesis in plants. During photorespiration, the active site of RuBisCo combines with oxygen and yields one molecule of phosphoglycerate and one molecule of phosphoglycolate while with carbon dioxide, it yields two molecules of phosphoglycerate.

What is photorespiration and why is it a problem?

In cellular respiration it is a positive term, a process vital to life. But photorespiration is an entirely negative term because it represents a severe loss to the process of using light energy in photosynthetic organisms to fix carbon for subsequent carbohydrate synthesis.

What is photorespiration vs photosynthesis?

Photosynthesis refers to the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water while photorespiration refers to a respiratory process by which plants take up oxygen in the light and give out some carbon dioxide, contrary to the general pattern of …

What process causes Photorespiration?

Photorespiration is a wasteful pathway that occurs when the Calvin cycle enzyme rubisco acts on oxygen rather than carbon dioxide.

What is Photorespiration and why is it a problem?

What is photorespiration Byjus?

Photorespiration is the chemical processes that occur within a living organism of phosphoglycolate that is produced during oxygenation catalyzed by the enzyme RubisCO and inhibits photosynthesis by interfering with CO2 fixation by RubisCO. To purge themselves of the phosphoglycolate the plant takes some steps.

What is photorespiration Ncert?

Photorespiration is a process that lowers the efficiency of photosynthesis in plants. In this process RuBP reacts with oxygen to release carbon dioxide. This happens during the Calvin cycle due to the catalytic activity of RuBP oxygenase.

What is the role of NADP+ in photosynthesis?

What is the role of NADP+ in photosynthesis? It is reduced and then carries electrons to the Calvin cycle. As part of the electron transport chain, it manufactures ATP. It assists chlorophyll in capturing light.
