Expert Solution
In adipose cells: Under high blood sugar levels, Insulin is secreted by pancreas and in response to that glucose is transported into adipose tisuues for its storage as fat.
Under low blood sugar levels, Under low blood sugar levels, glucagon hormone is secreted by pancreas which induces breakdown of fat in adipose tissues to normalise blood sugar levels.
In Brain: Glucose is the major fuel for brain. Glucose is transported into brain through specialised glucose transporters. Regulation of Glucose transport to brain is not yet a well understood phenomena. Though studies suggest that the glucose transport is regulated through the expression of GLUT transporters. Under low glucose levels, brain respond by increasing the expression of transporters and increasing the transporters with high glucose affinity. Under high glucose levels, brain cells downregulate the expression of high affinity transporters and upregulates the expression of low affinity transporters.

Insulin enhances the transport of glucose from the blood into
most of the body cells, its secretion is controlled by a
negative-feedback system between the concentration of glucose in
the blood and the insulin-secreting cells, therefore which of the
following statements is correct?
Select one:
a. A decrease in blood glucose concentration stimulates insulin
secretion, which in turn further lowers the blood glucose
concentration
b. An increase in blood glucose concentration stimulates insulin
secretion, which further increases the blood glucose...

Unlike liver cells, muscle cells do not secrete glucose into the
blood. What about glucose-6-P prevents its secretion and how do
liver cells overcome this problem?
McArdle’s disease (also called glycogen storage disease V) is a
genetic disorder in which muscle cannot make functional
phosphorylase. Speculate as to why McArdle’s patients show muscle
fatigue (tiredness) with even moderate exercise.
McArdle’s disease is inherited as a recessive trait. Consider

The following questions are related to glucose and its transport
into cells.
A. Why do cells need a protein to transport glucose across the cell
membrane? i.e.could glucose simply diffuse across the lipid
bilayer? (1 point)
B. Even after glucose is transported into the cell, there is
effectively no increase in intracellular glucose concentration.
This can be attributed to the action of hexokinase, the first
enzyme in the glycolytic pathway. Explain. (2 points)

Transport of glucose into epithelial cells lining your small
intestine is dependent on a pre-existing electrochemical gradient
of sodium (Na+) ions across the apical plasma membrane.
If that gradient is eliminated, glucose transport stops. This is
one example of ____________________.

secondary active transport (coupled transport)
primary active transport

A.
It is organic and gluten free.
