The Skeletal system is responsible for all but B) Produce Vitamin D.
Answer:
Option D
Explanation:
Whether a G alpha subunit is active or inactive depends on which guanine nucleotide is bound to it. Binding of GDP or GTP results in the protein switching between two conformational states.
Dissociation of GDP for GTP with the G alpha subunit structurally shifts the switch II helix region, allowing for the association of G alpha with its effector proteins, such as adenylate cyclase,describes the structural changes that occur in a G alpha subunit due to guanine nucleotide binding
