Question

Define C3 cycle and C4 cycle.

Answer 1

Answer:

C4 CYCLE

the alternative pathway of Calvin cycle (C3 cycle) taking place during the dark phase of photosynthesis. In the C4 cycle the first stable compound is 4 carbon compound, namely oxaloacetic acid. Hence it is called C4 cycle. It is a process of carbon dioxide fixation

Explanation:

c3 cycle the assimilation of carbon dioxide from the sunlight, for the process of photosynthesis and then converting it to glucose (energy) synthesizing different product is the key difference between the three. So during the CO2 fixation, when the photosynthetic plants produce 3-phosphoglyceric acid (PGA) or 3- carbon acid as the first product is called C3 pathway
