Question

Quizplus · Accepted Answer

When insulin binds to its receptors on target cells, it triggers a cascade of events including the phosphorylation of proteins in the plasma membrane, which is part of the signal transduction pathway. This leads to the insertion of glucose transporters into the plasma membrane, effectively increasing the number of active transport molecules for glucose, facilitating its uptake into cells.
