<prompt> When muscle glycogen is used for anarrobic glycolysis, how many ATPs are formed2347  <response>: Normally anarrobic glycolysis produces 2 ATPs - But the end product of muscle glycogendysis is glucose - 6 - phosphate. Glucose - 6 - phosphatase is absent in muscle. So the step catalysed by hexokinase Glucokinase is not needed. Hence the answer is 3.
