Enzymes

Any chemical that speeds up a reaction without being part of it.

Catalyst

Involves competition between inhibitor and substrate fir the active site.

Competitive inhibition

Inhibitor binds to enzyme somewhere other than the active site.

Noncompetitive inhibition

Anaerobic process - energy is conserved by substrate level phosphorylation and organic molecules serve as both the source and the final acceptors. Produce alcohol.

Fermentation

Process of conserving energy from wither organic or inorganic molecules via electron transport phosphorylation and using atmospheric oxygen or inorganic molecules as terminal electron receptors. ATP.

Respiration

Harvests energy from sunlight via the mechanism of electron transport phosphorylation.

Photophosphorylation
