1. Biochemistry of respiration
2. Raw materials… Any organic molecule
Carbohydrate
Lipid
Protein
3. They contain…
…too much chemical energy
4. So, respiration involves…
…breaking down large complex organic molecules to produce a molecule that contains a small amount of energy
5. ATP ATP is an immediate source of energy because:-
Only one step is necessary to release the energy
The amount of energy released is small enough to be useful.
6. Aim of respiration Synthesis of ATP
7. Carbohydrate is the major substrate for respiration
Soluble carbohydrates exist – so they can easily be transported
Insoluble carbohydrates exist – so they can be easily stored
8. Overview Four stages:-
1. Glycolysis
9.
2. Link reaction
10.
3. Krebs cycle
11.
4. Hydrogen / electron carrier system
12. GLYCOLYSIS Occurs in cytoplasm
Starts with Glucose
6 carbon compound
13. GLYCOLYSIS
Ends with Pyruvate
3 carbon compound
