Question

How does stage 2 of cellular respiration benefit a cell?

Answer 1

Krebs cycle

1. The process by which sugar is broken down in the presence of oxygen in the mitochondria of organisms (animals and plants) to release energy in the form of ATP is known as cellular respiration.
2. The 'Krebs Cycle' is the second stage of cellular respiration.
3. Within the cells, a catabolic reaction takes place.
4. ATP is the energy that is produced and stored in cells.
5. The TCA cycle, or citric acid cycle, is another name for the 'Krebs Cycle.'
6. All aerobic organisms use a sequence of chemical reactions known as oxidation-reduction reactions.
7. In eukaryotes, the second step of cellular respiration occurs in the mitochondrial matrix, which is critical for the generation of ATP molecules within the cells.
8. After the full oxidation of nutrients, a considerable amount of energy (ATP molecules) is created in this stage.
