When a muscle contracts anaerobically, more lactic acid is formed than when it contracts aerobically because:
When a muscle contracts anaerobically, more lactic acid is formed than when it contracts aerobically because:
a) oxygen inhibits fermentation of pyruvate to lactate.
b) under anaerobic conditions, most pyruvate is fermented to ethanol.
c) under aerobic conditions, most pyruvate is oxidized to CO
by the critic acid cycle.
d) glycolysis does not occur to a significant extent under aerobic conditions.
e) it’s been paralyzed by a 3000-fold excess of Botox.
