Metabolism |
totality of organism's chemical reactions |
|
|
Catabolic Pathway |
release energy by breaking down molecules into simpler compounds ex. cellular respiration |
|
|
Anabolic Pathway |
consume energy to build complex molecules from simpler ones ex. synthesis of amino acids |
|
|
Gibbs Energy |
delta G positive value=not a spontaneous reaction negative value=spontaneous reaction |
|
|
Exergonic Reaction |
net release of free energy |
|
|
Endergonic Reaction |
absorbs free energy from surroundings |
|
|
ATP |
generates heat changes protein shape energy coupling |
|
|
Cellular Work |
chemical= pushing of endergonic reactions transport=pumping of substances across membranes mechanical=beating of cilia, contractions |
|
|

Glycolysis |
in cytoplasm |
|
|
Substrate Level Phosphorylation |
ATP formed in reactions of glycolysis ex. citric acid cycle |
