Oxidation

Loss of electrons, gain of oxygen, loss of hydrogen, results in many C-O bonds and results in a compound with lower potential energy. (catabolic)

2

Reduction

gain of electrons, loss of oxygen, gain of hydrogen, results in many C-H bonds and results in a compound with higher potential energy (anabolic)

3

OIL

Oxidation is Loss of electrons

4

RIG

Reduction is Gain of electrons

5

Catabolic pathways

breakdown of complex molecules in to smaller molecules

6

Anabolic pathways

synthesis of more complex molecules from simpler ones

7

Redox reactions

A reaction in which both reduction and oxidation occurs

8

Glycolysis

Sugar splitting
Occurs in Cytoplasm
No Oxygen required
No required organelles
Takes place in both prokaryotes and eukaryotes
Involves a hexose sugar, usually glucose

1. 2 molecules of ATP are used to phosphorylate glucose. 2 ADP are released. 1 fructose biphosphate is produced
2. Lysis is used to split the fructose biphosphate into 2 glyceraldehyde-e-phosphate (G3P)
3.The 2 G3P molecules are oxidized. NADH is formed from NAD+. A phosphate group is added to the G3P. ATP is released by enzymes. 2 Pyruvates remain.

Net gain of 2 ATP
2 NADH are produced
Involves substrate-level phosphorylation, lysis, oxidation and ATP formation
Controlled by enzymes

9

Stages of aerobic respiration

Link reaction, Krebs cycle, oxidative phosphorylation
