Glucose is a simple six carbon sugar that
All cells and tissue is required for life-giving energy
Insulin is a hormone produced in the
Pancreas
Insulin has what effect on the level of plasma glucose

Increases plasma glucose
This term refers to a stored form of glucose found in the muscles and liver
Glycogen
What is the term used to describe an elevated blood glucose level
Hyperglycemia
What is the term used to describe a low blood glucose level
Hypoglycemia
Glucose levels in the blood must be maintained within a homeostatic range of
70 to 100 mg/dL
The ADA recommends the hemoglobin A1C as the best test to determine whether a patient’s blood sugar level has been under control during the previous

Good and bad
This ratio provides an important index for determining cardiac risk
TC/HDL ratio
Desirable cholesterol levels should be
Below 200 mg/dl
Elevated levels of cholesterol contribute to an increased risk of
