Hello. This question is incomplete. The full question is:
" Which explains how the Calvin cycle and the Krebs cycle differ? The Calvin cycle uses ATP to make glucose. The Krebs cycle uses ADP to make glucose. Only the Calvin cycle occurs in plant cells. The Krebs cycle only repeats in animal cells. "
Answer:
The Calvin cycle uses ATP to make glucose.
Step-by-step explanation:
The Krebs Cycle, or also known as the citric acid cycle because it is the first substance to be formed during the cycle, is one of the stages of the cellular respiration process of aerobic organisms, occurring inside the mitochondria of eukaryotic cells. This cycle, composed of eight enzymatically controlled reactions, begins with oxidation degradation, a reaction of oxalacetic acid with acetyl-coenzyme-A, a substance originated in glycolysis as a result of the catabolic action of the enzyme dehydrogenase on pyruvate (highly energy), producing two CO2 molecules.
The Calvin cycle is part of the photosynthesis process and is one of the reactions that occur in the stage known as carbon fixation reactions. This process, discovered by Melvin Calvin, represents one of the main CO2 fixation routes found in photosynthetic organisms. The Calvin cycle can be explained in three stages: fixation, reduction and regeneration of RuBP.
The main difference between this cycle and the Krebs cycle is that the Calvin cycle uses ATP to produce glucose.
