What happens to all the energy released during respiration?
It gets released inside the cell
It gets stored in the form of high energy chemical intermediates i.e., ATP, NADH and FADH2
It gets dissipated outside the cell
Fate of released energy cannot be determined
The correct option is B It gets stored in the form of high energy chemical intermediates i.e., ATP, NADH and FADH2
During the break down of respiratory substrates within a cell, all the contained energy is not released free into the cell, or in a single step. Rather, it is released in a series of slow, stepwise, enzyme controlled reactions, and it is trapped as chemical energy in the form of ATP, NADH and FADH2.
