High temperatures and bright light conditions can both promote photorespiration. This process is more likely to occur when there is an excess of oxygen compared to carbon dioxide in the plant cells, which can happen under conditions of high light intensity and high temperatures.

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 wastful process?

Photorespiration is considered wasteful because it consumes energy and resources without producing useful compounds for the plant. It occurs when rubisco enzyme fixes oxygen instead of carbon dioxide, leading to the release of CO2 and consumption of ATP and reducing power. This process reduces the efficiency of photosynthesis and can limit plant growth in certain conditions.


Why doesn't photorespiration occur in chemoautotrophs?

Photorespiration occurs in plants because they use oxygen in the Calvin cycle, leading to the wasteful process. Chemoautotrophs do not utilize the Calvin cycle for carbon fixation; instead, they use alternative pathways like the reductive tricarboxylic acid cycle or the 3-hydroxypropionate bi-cycle. This means that they do not produce the same conditions that lead to photorespiration as seen in plants.


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.

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.

Where is Photorespiration located?

Photorespiration involves three different organelles--- chloroplasts, peroxisomes and mitochondria

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.

What would most probably occur if plant gene alterations cause the plants to be deficient in photorespiration?

Plants deficient in photorespiration would likely exhibit reduced growth and productivity due to impaired carbon dioxide and energy metabolism. They may also show increased sensitivity to environmental stresses such as high temperatures and drought due to the role of photorespiration in stress tolerance. Ultimately, the overall fitness and survival of these plants could be compromised.


What are the environmental conditions called that keep a population from increasing in size and help balance the ecosystem?

These environmental conditions are known as limiting factors. They include factors like food availability, predation, competition, and habitat space that restrict population growth and maintain a balance in the ecosystem.

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
