Chemical reactions that break down complex organic molecules into simpler ones are called:
Catabolism
Chemical reactions that combine simple molecules and monomers to form complex structures are known as.
Anabolism
When the terminal phosphate is cut off ATP what is formed?
Adenosine diphosphate
Oxidation is
The removal of electrons
Reduction is the

This is a derivative of vitamin B.
NAD
Which of the following is not a form of phosphorylation?
Reduction phosphorylation
Glycogenesis is NOT
one way to make glycogen
This process is the synthesis of triglycerides.
Lipoogenesis
This reaction oxidizes acetyl co-A to produce carbon dioxide, ATP, NADH=H and FADH2.
Krebs cycle
Glycolysis, formation of acetyl co-A, Krebs cycle and the electron transport chain are involved in:
