What four enzyme activities unique to gluconeogenesis are needed to bypass the three irreversible steps of glycolysis. Draw the reactions catalyzed by these four enzymes.

1. Ion channels contain a selectivity filter that (choose best answer)

a) selects for positively charged ions by virtue of the negatively charged amino acids lining the pore, but allows similar ions through, like Na+ and K+.

b) selects for size of ions based on interactions with the ion transport protein.

c) binds with extreme sensitivity to their specific ion, akin to an enzyme forming a specific binding site for a substrate.

d) selects for ions based on size and charge due to the width of the channel and charge of amino acids lining the channel.

2. What is the role of K+ -gated ion channels in an action potential?

a) They do not have a role in action potentials

b) They provide the energy for the sodium potassium pump to reestablish resting potential

c) They lead to the action potential reaching its highest state of cell depolarization

d) They help reverse the action potential by repolarizing the cell.

3. Which of the following has the lowest electron affinity

a) Cytochrome c reductase complex

b) NADH dehydrogenase complex

c) Oxygen

d) Cytochrome c oxidase complex

4. The low redox potential of NADHmeans that is has a

a) High electron affinity

b) Very stable bond

c) Low free energy

d) Tendency give up electrons
