Question #772f2
1 Answer
It depends on which type of respiration you are talking about...
Explanation:
Respiration is a process by which a cell acquires energy by oxidation of certain compounds.PRESENCE OF OXYGEN IS NOT MANDATORY FOR OXIDATION.
Respiration is mainly of two types:
- Aerobic
In aerobic respiration, the cell uses oxygen to oxidise respiratory substrate, mainly carbohydrate .It is completed in Three steps:
Glycolysis
Oxidation of pyruvic acid
Kreb's cycle
But in aerobic prokaryotes, both these processes occur in cytoplasm.
- Anaerobic
In anaerobic respiration, cells oxidise compounds without the use of oxygen. Only glycolysis occurs in this type of respiration which is a 10 step process
These biochemical reactions are catalysed by various enzymes, coenzymes and cofactors.
