Incorrect Question 19 of 22 Map this question was written by sapling learning Chuan Xiao at Un versity of Texas at El Paso Refer to Lehninger, Box 12-2 (G Proteins: Binary Switches in Health and Disease). Note: Two items will not be used. One item is duplicated and both will be used. Guanosine nucleotide Regulators of G protein G proteins exchange factors signaling GTPase activator proteins Increase GTPase activity Modulate how long Inhibit GTPase activity Bind GTP, GAPs, GEFs of small G proteins G protein signal lasts (copy 1) of small G proteins Modulate how long Increase GTPase activity Large family of proteins G protein signal lasts (copy 2) of heterotrimeric G proteins with GTPase activity Generate GTP pool Stimulate the replacement of to serve as energy source GDP with GTP in G proteins A Previous Give Up & View Solution Check Answer Next H Exit

Explanation / Answer

G proteins - Large family of proteins with GTPase activity

Guanosine nucleotide exchange factors -Stimulate the replacement of GDP with GTP in G proteins, Modulate how long G protein signal lasts

GTPase activator proteins - Increase GTPase activity of small proteins, Increase GTPase activity in heterotrimeric G proteins

Regulators of G protein signaling - Increase GTPase activity of heterotrimeric G proteins, Modulate how long G protein signal lasts
