Which of the following hormones inhibits gluconeogenesis, the formation of glucose from noncarbohydrate sources such as amino acids, glycerol, and fatty acids?

A.

Insulin

B.

Epinephrine

C.

Cortisol

D.

Glucagon

A cardiovascular risk marker is an analyte in a body fluid that can be measured by the clinical laboratory and has been associated with the development of cardiovascular disease. Examples of risk markers include: LDL-C, triglycerides, and hs-CRP.

A cardiovascular risk factor is a condition (not a laboratory analyte) that is associated with an increased risk of developing cardiovascular disease. Examples of risk factors include: smoking, obesity, diabetes and hypertension.

Determine if each of the following is a cardiovascular risk marker or a cardiovascular risk factor.

1. Smoking

2. Obesity

3. Low density lipoprotein (LDL)

4. Hypertension

5. Triglycerides

6. High sensitivity-C-reactive protein (hsCRP)

A.

Cardiovascular risk factor

B.

Cardiovascular risk marker

S. aureus does not have capsular material as a defense mechanism. H. influenzae, K. pneumoniae, N. meningitidis, and S. pneumoniae each have capsular material use as a defense mechanism. This capsular material is an antiphagocytic substance which helps deter bacterial death by macrophages and other white blood cells.
