Question

What is the significance of step-wise release of energy in respiration?

Answer 1

Part 1: Significance of step wise release of energy in respiration

• The process of respiration occurs in multiple steps: glycolysis, the link reaction, krebs cycle and electron transport system and oxidative phosphorylation.
• The product of one pathway forms the substrate of the other pathway.
• The molecules produced during the various steps are also utilised in other biochemical processes.
• The energy molecules produced are also used in certain steps of respiration.
• The stepwise release of energy makes the system more efficient in extracting and storing energy.
