Question

Quizplus · Accepted Answer

Muscle tissue can replenish citric acid cycle intermediates through the purine nucleotide cycle, which is particularly important during intense exercise when the demand for ATP is high. This cycle helps to maintain the supply of citric acid cycle intermediates, which are necessary for continued ATP production. Other tissues like the liver, kidney, and heart have additional metabolic pathways to replenish these intermediates, such as gluconeogenesis and the use of amino acids.
