Answer:
True
Explanation:
Biologists often use energy sources as electron donors because electron donors transfer the electron which results in the release of the energy which helps in the production of ATP which is a source of energy in the cell.
The electron donor like NADH release electron in the electron transport chain and gets reduced to NAD+. This release of electron allows the flow of H+ across the mitochondrial membrane against their concentration gradient and when hydrogen ions come back into the mitochondrial matrix through ATPase it forms ATP. Therefore the statement is true.
