What is the role of enzymes in photosynthesis and cellular respiration?
Answer and Explanation: Enzymes are biological molecules that significantly speed up (catalyze) nearly all chemical reactions in cells, including cellular respiration. They boost the probability of a response by lowering the energy necessary for it to happen. The reaction leaves enzymes unaffected in the process.

What is the role of enzyme in respiration?
In cellular respiration, enzymes work to catalyze chemical reactions. This means they help make and create chemical bonds. In the first stage of cellular respiration, glycolysis, enzymes will phosphorylate glucose. Phosphorylation simply helps the glucose be more reactive so it can split easily.

What are the common enzymes for photosynthesis and respiration?
Cytochromes are membrane-bound hemeproteins containing heme groups and are primarily responsible for the generation of ATP via electron transport. It is common in both photosynthesis as well as respiration.

What is the use of enzymes in photosynthesis?
The enzyme Rubisco, short for ribulose-1,5-bisphosphate carboxylase/oxygenase, is the enzyme that incorporates CO2 into plants during photosynthesis. As it constitutes about 30% of the total protein in a plant leaf, Rubisco is probably the most abundant protein on earth and a major sink for plant nitrogen.
