Question

Answer the following question.

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

Short Note

Solution

In ETS energy is released in stepwise manner to prevent damage of cells.

  1. A stepwise release of the chemical bond energy facilitates the utilization of a relatively higher proportion of that energy in ATP synthesis.
  2. Activities of enzymes for the different steps may be enhanced or inhibited by specific compounds. This provides a means of controlling the rate of the pathway and the energy output according to needs of the cell.
  3. The same pathway may be utilized for forming intermediates used in the synthesis of other biomolecules like amino acids.
