The correct answer is active hyperemia.
Active hyperemia represents the increase in organ blood flow (hyperemia) that is associated with the increased metabolic activity of that organ. In this case, the increase in blood flow accompanies muscle contraction during the exercise. Muscle contraction stimulates the production of vasoactive (vasodilative) substances that dilate the vessels and thus, bring more oxygen to the muscles.
Answer:
a) No; b) Yes; c) Down
Explanation:
a) No: Rotenone inhibits the transfer of electrons from complex I to CoQ of the electron chain by inhibiting the oxidation of NADH to NAD.
b) Yes: Besides receiving electrons from complex I, FADH2 receives electrons from fatty acids and glycerol-3-phosphate. 2 ATPs are produced from FADH2.
c) Down: Less oxygen will be broken down (or consumed) to water, instead some of it will be converted to reactive oxygen species.
