Metabolism
chemical processes occurring within a living cell or organism that are necessary for the maintenance of life
Glycolysis
the anaerobic breakdown of glucose to lactic acid, with the net energy gain of two molecules of ATP
Photosynthesis
Allows cells to harness energy from sunlight and provided independence from the utilization of preformed organic molecules.
Oxidative metabolism
Present day cells use this mechanism as their principal source of energy.
Cells evolved in
a sea of organic molecules
Order of development
Glycolysis -> Photosynthesis -> Oxidative metabolism
