This requires energy. These molecules can be recycled so that a constant stream of energy rich ATP is available for all metabolic pathways in the cell. Almost all cellular processes need ATP to ...

In glycolysis, phosphate groups are transferred directly from sugar molecules onto ADP to form ATP. The whole pathway is pure chemistry, involving the reaction of one molecule with another ...

Most cells use glucose for ATP synthesis, but there are other fuel molecules equally important for maintaining the body's equilibrium or homeostasis. Indeed, although the oxidation pathways of ...
