Answer:
The Calvin cycle is the biochemical cycle that occurs during the dark phase of the photosynthesis process, also called the pentose cycle. This cycle consists of providing glucose and other organic compounds to the plant by fixing carbon from atmospheric CO2 and the action of the key cycle enzyme, ribulose bisphosphate carboxylase oxidase ("RuBisCO"), followed by various reactions. redox of products obtained during the first phase of photosynthesis, ATP and NADPH. In short, this cycle aims to produce glucose.
The Krebs Cycle or Citric Acid Cycle is one of the metabolic stages of aerobic cellular respiration that occurs in the mitochondrial matrix of animal cells. The function of the Krebs cycle is to promote the breakdown of end products of carbohydrate, lipid and various amino acid metabolism. These substances are converted to acetyl-CoA, with the release of CO2 and H2O and synthesis of ATP. In short, this cycle aims to produce ATP.
