Question:

When insulin is released, it acts to increase the absorption of glucose into skeletal muscle predominantly through which of the following transporters?

Inactive
Madeline F.
Answer:

GLUT 4! It is found in adipose tissue and muscle, and mediates insulin-stimulated glucose uptake; in fact, it is the ONLY insulin-responsive glucose transporter. Insulin acts via its receptor to translocate GLUT4 to plasma membrane. Also stimulated by exercise through insulin-dependent pathway.

Question:

What happens to equilibrium constant (Kw) as temperature increases?

Inactive
Madeline F.
Answer:

As temperature increases, Kw increases as well because the dissociation of water is an endothermic process. Heat is a reactant here, so increasing heat shifts the reaction to the right (forward) and Kw increases and pH decreases!
