photorespiration is when too much oxygen is build up from the light reactions. eventually the amount of oxygen surpasses the amount of carbon dioxide produced from the calvin cycle .
phtorespiration is a bad since ATP is only spended , but it can buy the plant time, becuase it is still able to build glucose into photosynthesis.
What else can I help you with?
What is the major consequence of photorespiration?
it lowers the efficiency of photosynthesis by removing carbon molecules from the Calvin cycle.
Does photorespiration produce energy?
No, photorespiration does not produce energy. In fact, it is considered a wasteful process that occurs in plants when there is a lack of carbon dioxide and excess oxygen in the leaf cells. Photorespiration can decrease the efficiency of photosynthesis in plants.
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.
Is photorespiration independent of light intensity?
Photorespiration is not independent of light intensity; it is suppressed at high light intensity due to the greater availability of CO2 for photosynthesis. Under low light conditions, photorespiration can become more prevalent as there is a higher ratio of oxygen to CO2 in the leaf, leading to increased oxygenation of ribulose bisphosphate.
How plants adopt themselves to avoid photo respiration?
Plants have evolved different mechanisms to avoid or reduce photorespiration, such as C4 and CAM photosynthesis. In C4 plants, like corn and sugarcane, carbon dioxide is initially fixed into a 4-carbon compound in the mesophyll cells before entering the Calvin cycle in the bundle sheath cells, which helps minimize the effects of photorespiration. CAM plants, like succulents, open their stomata at night to take in carbon dioxide and store it as organic acids, which are then broken down during the day to release CO2 for photosynthesis, reducing water loss and photorespiration.
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
Which takes plae in the chloroplast?
Major process is photosynthesis. Also involve in photorespiration
Where is Photorespiration located?
Photorespiration involves three different organelles--- chloroplasts, peroxisomes and mitochondria
What function does the chloroplast of a flower do?
That is same in all. Carryout photosynthesis. Also involve in photorespiration
What is the major consequence of photorespiration?
it lowers the efficiency of photosynthesis by removing carbon molecules from the Calvin cycle.

What has the author Israel Zelitch written?
Israel Zelitch has written: 'Photosynthesis, photorespiration, and plant productivity' -- subject(s): Photosynthesis, Plants, Respiration
What are the advantage and disadvntage of photorespiration?
Advantage: Photorespiration helps to salvage energy and prevent damage to the plant from reactive oxygen species. Disadvantage: Photorespiration decreases the efficiency of photosynthesis by wasting energy and reducing carbon fixation, ultimately leading to lower yields in plants.
What is photorespiration?
Photorespiration is a process in plants that occurs when rubisco, the enzyme responsible for carbon fixation, uses oxygen instead of carbon dioxide. This can happen in hot or dry conditions, leading to a wasteful process that reduces the efficiency of photosynthesis. Photorespiration can lower the productivity of plants.
Is photorespiration independent of light intensity?
Photorespiration is not independent of light intensity; it is suppressed at high light intensity due to the greater availability of CO2 for photosynthesis. Under low light conditions, photorespiration can become more prevalent as there is a higher ratio of oxygen to CO2 in the leaf, leading to increased oxygenation of ribulose bisphosphate.
Why is photorespiration a waste?
Photorespiration is considered a waste process because it consumes energy and releases carbon dioxide without contributing to the production of carbohydrates, which is the main purpose of photosynthesis. It can reduce the efficiency of photosynthesis and limit plant growth under certain conditions, such as high temperatures or low carbon dioxide levels.
