atp is required for what processes
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.
