ATP is consumed in the cell by energy-requiring (endergonic) processes and can be generated by energy-releasing (exergonic) processes. In this way ATP transfers energy between spatially separate metabolic reactions. ATP is the main energy source for the majority of cellular functions.ermentation entails the generation of energy via the process of substrate-level phosphorylation in the absence of a respiratory electron transport chain. In most eukaryotes, glucose is used as both an energy store and an electron donor.
Energy is required for cells to perform many functions. Enzymes convert substrates into products but must do so against the activation energy (so energy is needed here). Cellular respiration requires some amount of energy to occur. The most important energy consumer is the Na+/K+ ATPase ion pump which is responsible for maintaining cellular gradients and consumes approximately 50% of the energy of the cell.
