Answer #1

Answer- c. cooperate by interconverting pyruvate and lactate.

This happens with the help of Cori cycle.

It's a metabolic pathway in which lactate produced in muscles (during extensive activity) is transported to liver and converted to glucose (via pyruvate), which is then used again to produce lactate in the muscles.

Many metabolic disorders have similar symptoms because of the connections between pathways. The more severe form of lactate dehydrogenase deficiency and a deficiency in phosphofructokinase-1 in muscle can have similar symptoms of exercise intolerance, including fatigue and muscle pain during strenuous exercise. Individuals with phosphofructokinase-1 deficiency have more severe symptoms. Treatment for both individuals includes avoidance of high-intensity exercise. Along with other similar symptoms, both deficiencies can also result in reduced lactate levels during exercise. In order to distinguish between...

ii. During the transfer of acetyl CoA from the mitochondrion to the cytosol, malate will be generated in the cytosol. Although malate can be brought back into the mitochondrion directly, it will instead be converted into pyruvate which then enters the mitochondrion. Why does this happen? 1 point a. The conversion of malate into pyruvate generates NADPH which can be used in fatty acid synthesis. b. Movement of malate into the mitochondrion requires a lot of energy. c. In the...
