When there is not enough carbohydrate available in cells to allow the acetyl-CoA to enter the citric acid cycle, it undergoes ketogenesis and is converted into ketone bodies such as acetoacetate, beta-hydroxybutyrate, and acetone. These are used by the body as an alternative fuel source, especially during prolonged periods of fasting, low-carbohydrate diets, or strenuous exercise.

Question 9

To maintain a healthy body weight, Shaundra needs to eat 1850 calories per day. To be within the DRIs recommendations for total fat intake, which of the following amounts of total fat should be her upper limit

Therefore, choice C (45 grams) is the correct answer.

Question 10

A high-fat meal contains ____ calories in the same volume as compared to a low-fat meal.

Question 18

Gary had the following blood levels (mg/100 mL): cholesterol 245, HDL 35, LDL 99. Which of these blood lipid levels put him at risk for heart disease?

Accepted Answer

Cholesterol levels above 240 mg/100 mL are considered high and put an individual at risk for heart disease. HDL (High-Density Lipoprotein) levels below 40 mg/100 mL are also considered a risk factor for heart disease, as HDL is the "good" cholesterol that helps remove other forms of cholesterol from the bloodstream. Gary's LDL (Low-Density Lipoprotein) level is within the near optimal range (100-129 mg/100 mL), so it does not directly put him at risk based on the given values.
