Cellular Respiration
Glycolysis -this step happens in cytoplasm "The splitting of sugar"
Electron Transport Chain- ("the big ATP payoff") , occurs in the christae of the mirochondria, the folded membranes inside the chloroplast.
Kreb's Cycle, also known as Citric Acid Cycle - occurs in the mitochondrial matrix, the liquid-y part of the mitochondria.
Only about 30% the energy released by the cellular respiration of glucose is captured in the production of ATP; much of the energy is lost as thermal energy.
The products of this process are carbon dioxide and water, but the energy transferred is used to break bonds in ADP as the third phosphate group is added to form ATP (adenosine triphosphate).
Cellular Respiration is the major process that produces ATP, so chemical energy is available in the form that is used for many biological processes.
Electrons from Hydrogen are carried by NADH and passed down an electron transport chain to result in the production of ATP. Results in the production of ~32 ATPs for every glucose.
Aerobic Cellular Respiration- requires oxygen (O2) in order to create ATP
Adenosine triphosphate (ATP)- the biochemical way to store and use energy
it requires O2 as an electron acceptor at the end of the electron transport chain. When O2 is not available, cells use fermentation, which produces much less ATP per glucose molecule.
in aerobic cellular respiration, 29 molecules of ATP are produced per molecule of glucose.
Alcoholic Fermentation
Lactic Acid Fermentation 
the hydrolysis of ATP provides the energy for many biological processes (e.g. synthesizing molecules and pumping ions into and out of cells).
ATP is synthesized from ADP plus a phosphate using chemical energy released when organic molecules like glucose undergo a process called cellular respiration.
The hydrolysis of ATP supplies energy for many biological processes via coupled reactions in which the first reaction provides the energy required for the second reaction
The hydrolysis of ATP typically occurs after the ATP is bound to a substrate molecule.
This is how the exergonic hydrolysis of ATP is coupled with an endergonic conformational change (movement) or an endergonic synthesis reaction.
Cellular respiration can produce ATP using glucose, fatty acids, glycerol or amino acids as input molecules
