1

The hydrolysis of ATP that often occurs simultaneously with the synthesis of many compounds is an example of

couple reactions.

2

How soon would death occur from starvation if the body was unable to shift to a state of ketosis?

Within 3 weeks

3

Your roommate Demetrius is participating in a weightlifting course & complains of a burning pain during workouts. You explain to Demetrius that the rapid breakdown of glucose in his muscles produces large amounts of pyruvate, which leads to a fall in pH within the muscle & that the muscle responds by converting excess pyruvate to

lactate.

4

Which of the following is a consequence of alcohol intake?

Antidiuretic hormone production is suppressed

5

Bing drinking is defined as the successive consumption of

4-5 drinks

6

When energy-yielding nutrients are consumed in excess, which one(s) can lead to storage of fat?

Fat, carbohydrate & protein

7

Which of the following is a possible fate of acetyl CoA?

Synthesis to fatty acids

8

Which of the following is not a possible fate of metabolized glucose?

Urea

9

Which of the following defines a moderate level of alcohol intake per day for the average-sized man?

Up to 2 drinks

10

Glycolysis is the conversion of

glucose to pyruvate.

11

What organ is first to absorb alcohol after a person takes a drink?

Stomach

12

How are ketones formed?

Condensation of actyl CoA molecules

13

Of the total amount of carbohydrate energy consumed by the body, approximately what percentage is used by the brain & nerve cells?

50

14

Which of the following can be synthesized from all three energy-yielding nutrients?

Acetyl CoA

15

The formation of glycogen by the liver cell is an example of

anabolism.

16

A typical cell contains "powerhouses," which is another name for the

mitochondria.

17

Adverse side effects of typical low-carbohydrate diets include all of the following except

high blood pressure.

18

The Cori cycle involves the interconversion of

lactate & glucose.

Approximately what percentage of the body's energy expenditure is furnished by amino acids?

10 to 15

26

In the adult body, food energy not stored as fat or glycogen is lost as

heat

27

A feature of ketosis is that it

occurs when fats are partially oxidized.

28

An immediate consequence of a cellular deficiency of oxaloacetate is a slowing of

the TCA cycle.
