A) In this reaction, Acetaldehyde + NADH + H+ --> ethanol + NAD+
1. Acetaldehyde is the reducing agent
2. Acetaldehyde is the oxidizing agent
3. NAD+ is oxidized
4. NADH is the oxidizing agent
B) In ATP synthase complex, the F0 portion:
1. serves as proton channel
2. goes through conformational change to release ATP
3. oversees transport of ATP from mitochondria of eukaryotic cells
4. pumps proton against concentration gradient
Homework Answers
A) In this reaction of alcoholic fermentation, Acetaldehyde is reduced to alcohol and NADH+H is oxidized to NAD+. Therefore NADH+H is the reducing agent and Acetyldehyde acts as the oxidizing agent.
Therefore the correct option is option 2.
2) In ATP synthase, there are two subunits: F0 and F1. F0 is the integral membrane part and F1 project out of the membrane. The F0 subunit has a proton channel through which protons move from higher concentration to lower concentration (down the gradient). The transport of protons through F0 causes the conformational change in the F1 part to release ATP.
Therefore the correct option is option 1.
Thank you

Microbiology In the competitive inhibition of enzyme activity, which statement is correct? Inhibitor directly competes with the substrate. Less substrates must be added in order to reach Vmax. The number of active sites is unlimited. None of the above. In the noncompetitive inhibition of enzyme activity, which statement is correct?Inhibitors will cause a conformational change in the enzyme, more substrate must be added to reach Vmax, Enzymes bound to the inhibitor can still bind substrate, none of the above. ....
