Exam 3: Carbohydrates

Match the transporter proteins with their major site of expression. -GLUT3

Enterocytes absorb only one form of carbohydrate.This form is ____.

The process of gluconeogenesis occurs mainly in the liver and,in cases of starvation,in the kidneys as well.

In order to be absorbed by the body,all digestible carbohydrates must be broken down into ____.

In skeletal muscle,hypercortisolism may lead to ____.

The purpose of the hexose monophosphate shunt is to produce ____.

A homopolysaccharide that is important in human diets is ____ and the end product formed from the complete digestion of this homopolysaccharide is ____.

Active transport requires energy for the Na-K pump to transport Na out of the cell,thereby driving the transport of another substance (e.g.,glucose)when the Na re-enters the cell down its concentration gradient.

Alcohol in beverages is degraded mainly in the liver cytosol with the production of one NADH for each ethanol molecule.Predict what effect consumption of alcohol would have on the activity of the liver malate-aspartate shuttle.

Glucose is transported from the lumen into the enterocyte by active transport using SGLT1 protein,which also requires Na as a co-transporter.

Where are the enzymes that catalyze the citric acid cycle located?
