Question

Quizplus · Accepted Answer

Macropinocytosis does not operate continually and is typically induced only in response to activation of cell-surface receptors by various stimuli. The ensuing activation of intracellular signaling pathways results in changes in actin dynamics and the formation of cell-surface protrusions known as ruffles, which then collapse to form macropinosomes.
