Fig. 3-12. Remember the function of the mitochondria? Look at the “enzymes” on the inner mitochondrial membrane. These
are the cytochromes.

Fig. 3-12. Here’s another reminder about mitochondria. Look at the matrix. This is the location of the enzymes of the TCA
cycle.

Now go to your notes for the story of what happens in
glycolysis when there is no oxygen present.
Look at the reaction between the first and second phases of glycolysis. It requires NAD.
What is the source of this NAD when there is no oxygen?

• What is another source of acetate?

Figure 2-15. Interconversion
between triglycerides and
fatty acids.
What does Objective 40 say
about the function of triglycerides?
19
Figure 2-13. Fatty acids.
Look at the number of C atoms. How
many acetates could come from this fatty
acid?How many “turns” of the TCA cycle would
result?

Fig. 2-18. Structure of an amino acid. (Review from Obj. 45)
22
To get rid of amino group from amino acid:
Deamination
Transamination
23
After removal of the amino group, the amino acid can be introduced
into the TCA cycle.
