10. phosphorylate ADP to ATP

Explanation:

Cellular respiration is the metabolic process by which energy in form of ATP is obtained in a cell. However, it occurs in three major stages namely: glycolysis, Krebs cycle and electron transport chain (oxidative phosphorylation).

- Glycolysis is the process where glucose is broken down to produce pyruvate, which is then processed into acetyl coA before it enters the next stage (Krebs cycle).

- Krebs cycle is the stage where series of REDOX reactions occur to produce OXALOACETIC ACID as a final product, which accepts acetyl coA for another cycle to begin.

- Electron transport chain (ETC) uses the energy derived from the electron carriers energy NADH and FADH2 to phosphorylate ADP to ATP in a process called CHEMIOSMOSIS.

you dont brother god luck
