Section I: Metabolism and Sugar Catabolism
What is metabolism?
What is catabolism and anabolism? How do these two processes relate to metabolism?
What is an enzyme, how does the enzyme change a chemical reaction?
How does ATP and ADP function?
What is an active site? What is a kinase?
What is glycolysis? Where does it occure in a prokaryotic versus eukaryotic cell?
What is the chemical formula for glucose? C6H12O6
Why does glycolysis start with a sugar like glucose? What is so special about glucose in terms of energy
production? How can sugars besides glucose be used in sugar catabolism?
What is the first process in glucose catabolism? Excitation of the glucose molecule by the addition of
phosphates from ATP input.
What does this excitation do? Breaks apart glucose to 3-Carbon molecules.
What is the point of NAD’s in aerobic versus anaerobic metabolism?
How much ATP is produced in glycolysis, gross versus net?
What is the point of fermentation during anaerobic metabolism? When is it used during aerobic
metabolism?
What is the point of putting a CoA onto acetyl?
What are the molecules that form citric acid during the Kreb’s cycle?
What are the products of the Kreb’s cycle?
How do you change a 3-Carbon molecules to a 2-C molecule?
What is the point of the electron transport chain?
What are the two forces that drive the flow of H’s back through the ATP Synthetase machinery?
What is ATP Synthetase?
Where does the Kreb’s cycle occur in a prokaryotic versus eukaryotic cell?
Where does the ATP Synthetase work in a prokaryotic versus eukaryotic cell?
What is a phenol red test? How does it tell you what metabolism is occurring?
What is the difference between catabolism, anabolism, metabolism, aerobic,
anaerobic?
What is the purpose of glycolysis, fermentation, the Citric Acid Cycle, the electron
transport chain and ATP synthetase?
What is the purpose of the mitochondria? What processes happen in the different
parts?
