ATPase enzyme histochemistry demonstrates ATPase activity in which tissue?

Explanation:
ATPase histochemistry is used to reveal the activity of ATPase in skeletal muscle fibers. In this assay, tissue sections are incubated with ATP, and where ATPase is active, ATP is hydrolyzed and a precipitate forms at those sites. This creates a visible pattern that highlights differences in ATPase activity among muscle fibers, which is why the technique is commonly used for studying skeletal muscle and differentiating fiber types. Nerves, liver, and glands don’t show the distinctive, useful ATPase staining pattern that this method provides in muscle tissue, so the demonstrated tissue is muscle.
