Cellular respiration is a way where O2 is combined with foodstuff molecules. The chemical energy is thereby changed to activities that are sustainable and ignoring waste products. The key metabolic stages in cellular respiration includes glycolysis, Krebs cycle, and electron transport chain.

Glycolysis is a way to break down glucose in order to produce energy. Krebs cycle is also referred to as citric acid cycle or tricarboxylic acid cycle (TCA). It is where the cells gets it energy. The electron transport chain is responsible for the transfer of electrons to the acceptors coming from the donor.

Passive transport is not a metabolic stage in cellular respiration. It is the movement of a solute from a high electrochemical potential to a lower electrochemical potential region of the cell.

Answer - Option 4 - Passive transport
