•Glucose that is consumed is used to make energy in the form of ATP, which isused to perform work and power chemical reactions in the cell.•During photosynthesis, light energy is stored in the form of ATP and NADPH,which are used to build a molecule of glucose from 6 molecules of CO2.•In order to make one molecule of glucose, 18 molecules of ATP and 12 moleculesof NADPH are required; since one molecule of NADPH equals three molecules ofATP, 54 ATP equivalents are required.Metabolism of CarbohydratesFree to share, print, make copies and changes.
