In human skeletal muscle, during anaerobic exercise the pyruvate formed from glycolysis is converted to lactate. Why is this reaction important?Question 4

Which enzyme is responsible for the conversion of ATP to ADP, providing energy for muscle contraction?Group of answer choicesMyosin ATPase.Lactate dehydrogenase.Creatine kinase.Citrate synthase.

Lactate formed in muscles can be utilised through _______________.

Following intense exercise lactate forms if there is little to no oxygen present. Which statement is TRUE?Select one alternative:Lactate dehydrogenase (LDH) oxidises pyruvate and reduces NADH + H+ to NAD+. At rest the lactate is cleared by the Cori Cycle.Pyruvate dehydrogenase (PDH) reduces pyruvate and oxidises NADH + H+ to NAD+. At rest the lactate is cleared by the Citric Acid Cycle.Lactate dehydrogenase (LDH) oxidises pyruvate and reduces NADH + H+ to NAD+. At rest the lactate is cleared by the Urea Cycle.Lactate dehydrogenase (LDH) reduces pyruvate and oxidises NADH + H+ to NAD+. At rest the lactate is cleared by the Cori Cycle.
