11. A) Name the membrane-bound enzyme that directly links the TCA cycle with the electron transport chain. Give its name in the TCA cycle and the electron transport chain.
B) Name at least two other starting points for substrates used in the electron transport chain.
C) Approximately how many protons are pumped for each of these electron transport chain starting points?
Homework Answers
11.
A. The membrane-bound enzyme in TCA cycle is succinate dehydrogenase. In ETC it is called as succinate-coenzyme Q reductase.
B. Two starting points for substrates are TCA cycle and glycolysis.
C. For each NADH that enters ETC, there will be 10 protons pumped into IM space. For two FADH2, there will be 6 protons pumped in IM space.

Oxidative energy generation occurs in three stages: 1. glycolysis 2. TCA cycle 3. electron transport chain. Stage 3 is where most ATP is generated. This process is done by multi-enzyme complexes in the mitochondria (Complex I, Complex II, Complex III, Complex IV and Complex V). If a frame-shift mutation occurred in the gene encoding a protein in one of these complex, identify the one that would cause the most harm and the least harm to the function of the electron...

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. ....
