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.
