Which of the following is/are rubisco substrates?

A. O₂
B. RuBP
C. CO₂, O₂, and RuBP
D. CO₂
E. CO₂ and RuBP

Answer :

Final answer:

The substrates for Rubisco are CO₂ and RuBP. Rubisco catalyzes a reaction between these substrates in a process known as carbon fixation, a critical part of photosynthesis. The correct option is e.

Explanation:

The substrates for the enzyme Rubisco, which plays a key role in the process of photosynthesis, are CO₂ and RuBP (Ribulose-1,5-bisphosphate).

Rubisco catalyzes a reaction between these two substrates, in a process known as carbon fixation. During this process, CO₂ reacts with RuBP to form a six-carbon compound, which is immediately converted into two molecules of 3-PGA (3-phosphoglycerate). This is a critical stage in the Calvin cycle of photosynthesis, where carbon is captured from CO₂ and incorporated into organic molecules.

Hence, Option e is correct.
