Smooth muscle can maintain a contraction for a relatively long time with minimal energy usage because the latch mechanism is present in smooth muscle.

Question

Quizplus · Accepted Answer

Smooth muscle cells have a unique mechanism called the latch mechanism, which allows the cells to maintain a contraction for an extended period with minimal energy usage. The reasoning behind it is also correct as the latch mechanism helps the cells maintain contractile force without the need for ATP hydrolysis. Thus, both the statement and the reason are correct and related.
