e. electron transport chain

a. glycolysis d. acetyl CoA b. citric acid cycle e. electron transport chain

Explanation:

Cellular respiration is set of metabolic processes that occur within the cell in order to produce usable energy (ATP) from the nutrients (food). It can be divided into four main stages:

Glycolysis-anareobic process in which glucose is broken down and it occurs in the cytoplasm. Products of glycolysis are 2 molecules of pyruvate and 2 molecules of ATP. Transition - Pyruvate form the glycolysis is transported into the mitochondria, where it is converted to a molecule Acetyl CoA used for further breakdown Citric acid cycle or Krebs cycle - aerobic process that occurs in the mitochondria matrix in which 4 molecules of ATP, and NADH are produced Electron transport chain-set of reactions that occur within the cristae of mitochondria. NADH and electrons are passed through electron transport chain to result in the production of ATP (32 ATPs for every glucose).
