In photorespiration, O2 replaces CO2 in a non-productive, wasteful reaction. Photorespiration occurs when the CO2 levels inside a leaf become low, which happens on hot dry days when a plant is forced to close its stomata to prevent excess water loss.

Photorespiration lowers the efficiency of photosynthesis by preventing the formation of?
3-phosphoglycerate molecules
Why do we need to wear gloves during an experiment?
So nothing happens.
What happens during halftime of earth?
Football games have halftime. The planet Earth does not.
What happens during stage 4 of cold water immersion.?
cardiac arrest
What happens to the potential of the molecules in a reaction?
the potential energy of the molecules changes during a reaction.
How do you increase photorespiration?
There is no need to increase photorespiration . It is an injurious process for plants . It is increased by strong sun light and high temperature as it happens at mid day .It specially happens in tropical regions .
Why is photorespiration such a waste?
Photorespiration is a wasteful process because: i. About 25 % of the CO2 fixed during photosynthesis is lost ii. There is no formation of ATP & NADH
What happens when RuBP reacts with O2?
According to Biologists, the process in which oxygen becomes attached to RuBp which is fixed is known as photorespiration. This process does not apply to carbon dioxide.
Why is photorespiration wastful process?
photorespiration protects plant from photooxidation and photoinhibition.
What is the difference between photorespiration and respiration?
photorespiration: RuBP accepts oxygen instead of CO2 during photosynthesis because production of oxygen has exceeded production of CO2. respiration: Oxygen is produced in oxidative phosphorylation/chemisosmosis and used to produce water during respiration.
Where is Photorespiration located?
Photorespiration involves three different organelles--- chloroplasts, peroxisomes and mitochondria
What happens during phtorespiration and why is it considered bad for plants?
When O2 is high concentration and Rubisco combines it to RUBD. It's bad because it can't make sugar/ATP. Photorespiration is the biosynthetic pathway that leads to the fixation of oxygen.
Is photorespiration independent of light intensity?
Photorespiration occurs in dry situations, where there is intense light. Desert plants are a great example. Therefore, no, photorespiration is not independent of light intensity.
Does photorespiration produce energy?
No, photorespiration actually wastes energy because no useful product is created when photorespiration occurs, and, as a result, the energy absorb from light earlier is wasted.
What is photorespiration?
Photorespiration occurs when a plant runs out of CO2 and begins adding O2 to RuBP in the Calvin cycle.
Can tomato plants show photo respiration?
No, tomato plants do not undergo photorespiration. Photorespiration is a process that occurs in C3 plants, where oxygen is mistakenly used instead of carbon dioxide in the initial steps of photosynthesis. However, tomato plants are classified as C4 plants, which have evolved mechanisms to minimize photorespiration.
Why doesn't photorespiration occur in chemoautotrophs?
Photorespiration doesn't happen because of this spatial separation. Chemoautotrophs are found in the deep sea. Autotrophs make their own food.
