Transcript of Krebs Cycle

Krebs Cycle


1 glucose will form 2AcoA, so there are two turns of the cycle per glucose

6C ACID
5C ACID
4C ACID
The aim of the krebs cycle is to make as many
HIGH ENERGY HYDROGEN
atoms as possible.

These can be used to make
ATP
on the electron transport chain.

This occurs in the
MATRIX
.
2AcoA
2x
2H
Reduced NAD (6 out)
Reduced FAD (2 out)
CO2
Decarboxylation occurs when number of carbon atoms falls.
Energy
ATP
Some energy is released sirectly to form ATP by SUBSTRATE LEVEL phosphorylation.
CO2
2H
SUMMARY

2C AcoA combines with 4C acceptor molecule.
6C molecule forms which breakdown to a 5C molecule then reforms 4C acceptor.
High energy Hydrogens's are made and CO2, (DECARBOXYLATION).
2x
2C AcoA
2ATP + 6 red.NAD + 2 red.FAD + 4CO2
