Question

T/F: Ribulose 1,5-biphospate is similar to oxaloacetate in the kreb's cycle in that they are both regenerated at the end of their respective cycle

Answer 1

The statement that Ribulose 1,5-bisphosphate is similar to oxaloacetate in the Krebs cycle in that they are both regenerated at the end of their respective cycle is True, enabling the continuous fixation of CO2 and oxidation of acetyl-CoA.

Step-by-step explanation:

Both Ribulose 1,5-bisphosphate in the Calvin cycle and oxaloacetate in the Krebs cycle are regenerated at the end of their respective cycles. In the Calvin cycle, Ribulose 1,5-bisphosphate (RuBP) is ultimately regenerated after the fixation and reduction stages, enabling continuous fixation of CO₂. Similarly, in the Krebs cycle (also known as the citric acid cycle), oxaloacetate is regenerated after the cycle of reactions that oxidize acetyl-CoA, which allows the cycle to process new acetyl-CoA molecules.
