Question

1. which hormone is largely responsible for facilitating the movement of glucose out of the blood and into the bodys cells?

a) testosterone
b) estrogen
c) glucagon
d) insulin

1. what is thought to be the underlying cause of metabolic syndrome?

a) insulin sensitivity
b) insulin resistance
c) high blood cholesterol
d) cigarette smoking

1. how might glycemic index be used to help people achieve better control of their blood glucose?

Explanation:

• Question 4: Insulin is the hormone that allows glucose to enter cells. Testosterone is a male sex hormone, estrogen is a female sex hormone, and glucagon raises blood glucose levels.
• Question 5: Insulin resistance, where cells don't respond well to insulin, is a key underlying cause of metabolic syndrome. Insulin sensitivity is the opposite (good response to insulin), high blood cholesterol is a risk factor but not the underlying cause, and cigarette smoking is a risk factor for many diseases but not the direct underlying cause of metabolic syndrome.
• Question 6: The glycemic index (GI) ranks carbohydrates based on how quickly they raise blood glucose. People can use it to choose low - GI foods (which cause a slower, more gradual rise in blood glucose) to better manage their blood glucose levels. For example, instead of white bread (high GI), they can choose whole - grain bread (lower GI).

Answer:

• 4) D. Insulin
• 5) B. Insulin resistance
• 6) By choosing low - glycemic index foods which cause a slower and more gradual increase in blood glucose levels.
