MULTIPLE CHOICE

 

1. A good example of living in an obesogenic environment is

a.	working for an employer who gives employees free membership at a health club.
b.	being a former high school athlete who now works in a sedentary job.
c.	living in an apartment complex where it is unsafe for children to play outside unsupervised.
d.	a physician’s recommendation not to exercise during recovery from surgery.

 

 

ANS:  C

Obesogenic environments limit people’s ability to stay active while surrounding them with inexpensive high-energy foods. Living in an apartment complex in an unsafe area would be considered obesogenic because it limits the ability to be active. Being given a free health club membership is antiobesogenic because it encourages physical activity. A high school athlete who becomes sedentary is not necessarily prohibited from engaging in active leisure-time activities. Needing to remain inactive during recovery from surgery is only temporary and so has less effect on long-term weight.

2. The total amount of energy in a bowl of soup that contains 5 g of protein, 2 g of fat, and 20 g of carbohydrate is _____ kcal.

a.	27
b.	108
c.	118
d.	133

 

 

ANS:  C

Protein provides 4 kcal/g; fat provides 9 kcal/g; carbohydrate provides 4 kcal/g. Therefore, the soup contains 118 kcal ([5 ´ 4] + [2 ´ 9] + [20 ´ 4] = 20 + 18 + 80).

3. The fuel for all body processes that traps energy released from food is

a.	electrons.
b.	acetyl coenzyme A.
c.	glucose-6-phosphate.
d.	adenosine triphosphate.

 

 

ANS:  D

The body catabolizes nutrients, and their energy is trapped in adenosine triphosphate (ATP), the fuel for all processes that require energy in the body. Electrons do not store energy. Acetyl coenzyme A is a substance that is produced in the sequence of reactions as nutrients are metabolized in the mitochondria. Glucose-6-phosphate is a substance that is produced in the sequence of reactions in the metabolism of carbohydrate.

4. If a person hears a friend calling for help and goes running to find out what the friend needs, the person would be getting his or her energy from

a.	fatty acids via adrenaline release.
b.	glucose and amino acids via aerobic pathways.
c.	glycogen via anaerobic glycolysis.
d.	fatty acids and glycerol via oxidative phosphorylation.

 

 

ANS:  C

Anaerobic pathways metabolize mostly glycogen for short-term, high-intensity activities. Adrenaline release may or may not stimulate this metabolism. Aerobic pathways are used for longer-term, moderate-intensity activities. Oxidation of fatty acids occurs mostly in long-term, moderate-intensity activities.
