Changes in Signal Transduction Pathways

AP Biology· difficulty 2/5

Cellular signaling pathways are typically terminated by

A
$Phosphatases (that remove phosphates) and GTPase activity (that turns off G proteins)$

B
$Continued ligand binding and sustained second messenger production$
C
$Cytokinesis (which separates the daughter cells from each other)$
D
$Permanent activation of receptors and prolonged kinase signaling$

Explanation

Signal off-switches: dephosphorylation, GTP hydrolysis on G proteins, ligand removal, receptor internalization.
