1
Glycerol 3-phosphate - a hydroxy ester; low energy
2
Resonance forms
3
A pyrophosphate
4
High-energy phosphates
5
Free energies of hydrolysis of several phosphates
6
Source of energy in an organism versus time of use.
7
ATP supplies energy for the pink and is made by the blue reactions.
8
Most reduced structure has most energy. Oxidation harvests the energy.
9
Fatty acid has lots of calories; glucose has less - already more oxidized.
10
A regular compound energetically
11
Chemiosmotic separation of protons provides the energy for oxidative phosphorylation.
12
Catabolism of polymer to simple unit of acetyl~CoA then complete oxidation and oxidative phosphorylation.
13
Energy charge = [ATP] + 0.5 [ADP]/[ATP] + [ADP] + [AMP]
How much is “charged” in the ATP form.
14
ATP
15
