When insulin binds its receptors on muscle cells, an increase in glucose uptake by the muscle cells is the result. this is an example of a effect by a hormone?

Direct effect

Explanation:

The direct effect caused by a hormone occurs when a specific hormone binds to the receptors of a cell phone in order to realize its biological effect.

As we can see from the question above, it was necessary for insulin (which is a hormone) to bind its receptors to muscle cells for muscle cells to capture glucose. Therefore, we can conclude that this is an example of direct effect.
