The most abundant protein in chloroplast is:
Correct answer: A. Rubisco
- A. Rubisco
- B. Ribulose
- C. Ribulose bisphosphate
- D. Cytochrome
Explanation
Carbon dioxide fixation in dark reaction is carried out by the enzyme Ribulose bisphosphate carboxylase, also known as Rubisco. It is the most abundant protein in chloroplasts, and probably the most abundant protein on earth. B.It is a 5 carbon( ketoses) carbohydrate and not protein. C.It is a 5 carbon sugar (carbohydrate) used in dark reaction of photosynthesis. D.It is a complex in thylakoid membrane acting as electron carrier.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
