Answer :
Final answer:
The substrates for the enzyme RuBisCO in photosynthesis are CO2, O2, and RuBP. option C
Explanation:
The correct answer is C) CO2, O2, and RuBP. The enzyme ribulose bisphosphate carboxylase, also known as RuBisCO, plays a crucial role in photosynthesis, where it catalyzes a reaction between CO₂ and RuBP (ribulose bisphosphate). This process is referred to as carbon fixation because CO₂ is transformed from an inorganic form into organic molecules. O2 is also a substrate for RuBisCO during a process called photorespiration. Therefore, the substrates for RuBisCO are CO2, O2, and RuBP.
