Practice Final Exam
1. True or False: The liver is the primary site of ketogenesis.
2. True or False: Muscles do not utilize fat (triglycerides) to produce ATP.
3. True or false: The muscles can secrete glucose into the blood stream to supply glucose
to the brain.
4. True or false: Because of its metabolic limitations, the brain can only use glucose and
ketones as a source of fuel.
5. True or false: Red blood cells can’t do aerobic cellular respiration because they lack
mitochondria.
6. After eating a meal containing carbs, fats, and proteins, which of the following pathways
would be occurring to the greatest extent in the liver?
a. Glycogenolysis
b. Gluconeogenesis
c. Ketogenesis
d. Glycogenesis
7. Using the words pyruvate, glycolysis, acetyl-CoA, and fatty acid synthesis, explain how
glucose can be used to make fat and under what metabolic conditions (fed/fasting) might
this occur.
8. In the beginning phase of the Atkins diet, dietary carbohydrates are severely restricted
which puts the body into ketosis, turning fat into ketones. Explain why this would not
happen if there more carbohydrates in the diet.
9. All of the following statements about BMI are true EXCEPT
a. Very low and very high BMI measurements are associated with increased risk of
mortality.
b. BMI is based on height and weight measurements.
c. BMI is an accurate measure for all body types, including athletes with a high
, amount of muscle mass.
d. BMI stands for body mass index.
10. Which of the following is NOT a benefit of modest weight loss?
a. Decrease in blood triglycerides
b. Decrease in HDL cholesterol
c. Decrease in LDL cholesterol
d. Decrease in blood pressure
11. All of the following contribute to an “obesogenic environment” except:
a. Sedentary jobs that require little movement
b. Wide availability of inexpensive, calorie-dense, nutrient-poor food
c. Less walkable neighborhoods
d. The tendency to gain weight as you age
12. Leptin is a hormone that plays a role in signaling the brain that
a. the body has produced an allergic response to a food that was consumed.
b. the body is becoming dehydrated.
c. the body is in need of food.
d. the body's need for food has been satisfied.
13. Gina is a moderately active person. Which of the following components makes the
largest contribution to her total energy expenditure?
a. Basal metabolic rate
b. Thermic effect of food
c. Physical activity
d. Non-exercise activity thermogenesis
14. Consuming more calories than you burn each day results in:
a. weight loss.
b. a positive energy balance.
c. a negative energy balance.
d. a recommended diet plan
15. Describe the trends in obesity in the US over the last 25 years and suggest several
reasons why these trends might be appearing.
16. What is a food desert?
17. The three components of total energy expenditure are:
a. Basal metabolic rate, physical activity, and adaptive thermogenesis.
b. Basal metabolic rate, physical activity, and the thermic effect of food.
