When your muscles are working aerobically, less lactic acid is formed than when

When your muscles are working aerobically, less lactic acid is formed than when they work anaerobically because:
a) muscle is metabolically less active under aerobic than anaerobic conditions
b) glycolysis does not occur to significant extent under aerobic conditions
c) the lactic acid generated is rapidly incorporated into lipids under aerobic conditions.
d) under aerobic conditions in muscle, the major energy-yielding pathway is the pentose phosphatepathway, which does not produce lactate
e) under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized bythe citric acid cycle rather than reduced to lactate
