Evaluate the role of GAP proteins in the GTP hydrolysis activity of RAS and signal termination.

GAP proteins accelerate the GTP hydrolysis activity of RAS, leading to signal termination and proper regulation of cellular responses.

GAP proteins inhibit the GTP hydrolysis activity of RAS, prolonging the signal and cellular responses.

GAP proteins phosphorylate RAS, enhancing its signaling capacity and prolonging cellular responses.

GAP proteins have no effect on the GTP hydrolysis activity of RAS or signal termination.
