photorespiration protects plant from photooxidation and photoinhibition.
Wiki User
∙ 14y ago
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.

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.
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.
What environmental conditions help photorespiration?
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.
Which situation best accounts for photorespiratin in plants?
Photorespiration is more likely to occur in plants when the ratio of oxygen to carbon dioxide is high, such as in hot and dry environments. This leads to Rubisco, the enzyme involved in photosynthesis, fixing oxygen instead of carbon dioxide, resulting in the wasteful process of 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
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.
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.
Which takes plae in the chloroplast?
Major process is photosynthesis. Also involve in photorespiration
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 the name of the process wherein co2 is released without the production of atp or nadph?
The process you are referring to is called photorespiration. It is a metabolic pathway that releases CO2 without producing ATP or NADPH and occurs in plants when the Calvin cycle is inhibited.
What happens when RuBP reacts with O2?
When RuBP reacts with O2 instead of CO2 in the Calvin cycle, a process known as photorespiration occurs. This results in the synthesis of a compound that can't be used to produce glucose, wasting energy and decreasing the efficiency of photosynthesis.
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 .
Where is Photorespiration located?
Photorespiration involves three different organelles--- chloroplasts, peroxisomes and mitochondria
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.
Which process requires electrons that are obtained by the splitting of water A cyclic photophosphorylation B noncyclic photophosphorylation C Photorespiration?
B noncyclic photophosphorylation requires electrons that are obtained by the splitting of water. The process involves the flow of electrons through both photosystem I and photosystem II to generate ATP and NADPH for the light-independent reactions of photosynthesis.
