CH 6 PART 2

Metabolism

Sum of all chemical reactions within an organism

Catabolism

Break larger molecules into smaller products, exergonic

Anabolism

Build large molecules from smaller ones. Endergonic

Oxidation Reduction Reaction

Any metabolic reaction that involves the transfer of electrons from an electron donor to an electron acceptor.

What happens to Electrons in reduction?

Electrons accepted

What happens to electrons during oxidation

Electrons are donated

Reduction Reaction way to remember electrons

OIL RIG - oxidation involves loss, Reduction involves gain

Phosphorylation

Inorganic phosphate added to substrate (adding a phosphate)

Substrate level phosphorylation

Transfer of phosphate to ADP from and other phosphorylated organic compound

Oxidative Phosphorylation

Energy from redox reactions of respiration is used to attach inorganic phosphate to ADP

Photophosphorylation

Light energy is used to phosphorylate ADP with inorganic phosphate
