(A) Describe the hallmarks of the GLUT transporter – a passive
glucose transporter, and the basis behind glucose transport in
erythrocytes. (4 pts); (B) How does insulin regulate glucose
transport and affect GLUT transporter?
Which of the following correctly depicts the mechanism of the
Na+/glucose co-transporter discussed in class?
Select one:
a)Both the Na and the glucose must bind which allows Na to move
against its gradient because glucose is moving down its
gradient.
b)Glucose is pushed against its gradient because Na will be
moving with its electrochemical gradient.
c)This transporter binds Na on the outside of the cell, then ATP
adds on a Phosphate, which changes the confirmation and open to
cells interior...

A) Compare/contrast how insulin and glucagon signal
different blood glucose levels and their effects on glycogen
breakdown, glycogen synthesis and glycolysis.
B) Compare the fates of glucose 6-phosphate from
glycogen breakdown in liver and muscle
Primary Active Transporter Na+/K+ ATPase pump. Describe how this
pump maintains Na+ and K+ ionic gradients across the cell membrane.
SECONDARY ACTIVE TRANSPORTERS: How do these secondary transporters
benefit from the ionic gradients created by primary active
transporters? What is the difference between
cotransport/countertransport?
(Please don't write the answer on a separate page all over the
place. I'm new to A&P 1 and I'm still learning, so I need to be
explained, rather than shown notes like what I take...
your topic is Protein Supplements
Compare and contrast different types of protein and amino acid
supplements. Who should use these?
Are these supplements helpful for building muscle or losing
weight?
Compare and contrast the activities of AMP-activated protein
kinase and cAMP dependent protein kinase. To answer this question,
address each of the points given here, labeling each point with
what you are addressing.

What are the hormones that lead to stimulation and inhibition of
these...
Cholera toxin inhibits the Na+/K+ATPase activity of intestinal
epithelial cells. Resulting with decreased uptake of glucose.
Describe why inhibiting the Na/K+ ATPase pump affects glucose
uptake in the intestine.
