In depth photosynthesis
WebPhotosynthesis consists of a number of photochemical and enzymatic reactions. It occurs in two stages. During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of … WebPhotosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other …
