Question

The most abundant protein in the world is the enzyme that initiates the fixation of carbon in the Calvin cycle. This enzyme is called:

a) rubisco.
b) glyceraldehyde 3-phosphate.
c) ATP-synthase.
d) ribulose biphosphate.
e) crassulacean acid."

Answer 1

The most abundant protein in the world that initiates the fixation of carbon in the Calvin cycle is rubisco.

Step-by-step explanation:

The most abundant protein in the world that initiates the fixation of carbon in the Calvin cycle is known as rubisco. Rubisco, or ribulose bisphosphate carboxylase/oxygenase, is an enzyme that catalyzes the addition of carbon dioxide to ribulose bisphosphate, resulting in the production of 3-phosphoglycerate (3-PGA). It plays a crucial role in the process of photosynthesis, where carbon dioxide is converted into organic molecules.
