A
-Lipofuscin pigment
-Metabolic lysosomal product
3
Q
A
-Actin microfilaments
4
Q
A
-Kinesin
5
Q
A
C. (Ek is equal to Em, no net movement of K+)
6
Q
A
B. (Em is more negative than Ek, K+ will move into cell)
7
Q
A
C. (Depolarizes. Because PNa increased, Em would want to move towards ENa which is much more positive than the resting membrane potential)
8
Q
A
B. (If K outside decreases, EK becomes even more negative (Nernst equation), dragging Em with it to hyperpolarized value. At rest, Em depends most on potassium because potassium channels are the only ones open (remember PK at rest)
9
Q
A
C. (Remember equilibrium potential (nest equation) does not depend on permeability
