Describe/define the term Glucagon.
Glucagon is a hormone that is important in the regulation of blood glucose. Glucagon is released by the pancreas in response to low blood glucose levels. It increases glycogen breakdown and release of glucose by the liver to increase blood glucose levels. Glucagon increases gluconeogenesis.
Describe/define the term Gluconeogenesis.
Gluconeogenesis is the production of new glucose by metabolic pathways in the cell. Amino acids derived from protein usually provide the carbon for the new glucose.
Describe/define the term Glucose.
Glucose is a monosaccharide with 6 carbons. It is also the primary energy source in the body.
Which hormone is released when blood glucose levels are high?
Insulin
Match the hormone with its effect on blood glucose.
Insulin = decreases blood glucose Glucagon = Increases blood glucose
Describe/define the term Insulin.
Insulin is a hormone that is important in the regulation of blood glucose. Insulin is released by the pancreas in response to high blood glucose levels. It increases glucose uptake by the muscles and adipose tissue. It increases glycogen synthesis and suppresses gluconeogenesis.

Which of the following are true of polysaccharides?
They are sometimes called starches. They are found chiefly in grains, vegetables, and fruits. They are made of single-sugar units that are bonded together to form a chain. They are sometimes called complex carbohydrates.
______ diabetes is strongly associated with physical inactivity, poor diet, and obesity.
Type 2
The treatment for Metabolic Syndrome is essentially the same as the treatment of what other disease?
Type 2 diabetes
What is the criterion for fasting blood glucose above which an individual is diagnosed as diabetic?
Under fasting conditions (at least several hours after eating), blood glucose normally varies between about 70 and 100 mg/dl of blood. However, if a fasting blood glucose level is equal to or above 126 mg/dl, it is classified as diabetes.
What is malting?
a process during which grain seeds sprout the first step in beer production
Which of the following foods consist predominately of carbohydrates? (Check all that apply.)
baked potatoes table sugar soft drinks
The cooking process is often viewed as the starting point of carbohydrate digestion because cooking helps
because cooking softens the tough, fibrous tissues of vegetables, fruits, and grains. When starches are heated, the starch granules swell as they soak up water, making them much easier to digest. -soften fibrous tissues. starch granules swell with water.

Describe/define the term Glycogen.
Glycogen is a polysaccharide. It contains many glucose units linked together with alpha bonds. It is the storage form of carbohydrate in humans and other animals. It is not a source of carbohydrate in our diets.

Regular meals consisting of a balance of protein, fat, and low glycemic load carbohydrates, plus ample soluble fiber, help prevent hypoglycemia. Individuals also should substitute protein-containing snacks for those that contain mostly sugar and aim to spread carbohydrate intake throughout the day. Finally, limiting caffeine and alcohol intake can be beneficial in preventing symptoms of hypoglycemia
