With Correct Solution

. BMR accounts for - ANSWER 65-75% of total energy output

The terms calorie (with a small c) and kilocalorie are often used interchangeably. -
ANSWER True

People usually use one energy nutrient at a time to fuel their activities. - ANSWER False

The caloric value of oxygen varies depending on whether carbohydrate or fat is the
primary fuel being used. - ANSWER True

Obesity can develop from a failure to balance fat intake with fat oxidation. - ANSWER
True

After you eat, most dietary carbohydrate is either used for cellular functions or
converted to glycogen for storage in the liver and muscles. - ANSWER True

Some experts have estimated that an intake of 2,000-2,500 kcal of carbohydrate over
several days, after carbohydrate stores were at maximum, would be required before
carbohydrate would be converted to fat. - ANSWER True

Fat stores are limited in size. - ANSWER False

Replacing dietary carbohydrates with fat promotes obesity. - ANSWER True

A diet that is high in fat and low in carbohydrate reduces the size of glycogen stores and
stimulates hunger. - ANSWER True

Fats in your diet are more satiating than carbohydrates and are more likely than
carbohydrates to turn off appetite. - ANSWER False

People who regularly consume a high-fat diet tend to eat more. - ANSWER True

When carbohydrate stores run low, fat oxidation slows. - ANSWER True

All fats have the same metabolic effects. - ANSWER False

Most people who expend more energy in exercise and physical activity oxidize more fat.
- ANSWER True

High intensity exercise has been shown to oxidize a higher proportion of calories from
fat. - ANSWER False

, the three principle components of daily total energy expenditure (TEE): - ANSWER
Basal/Resting Metabolic Rate (BMR or RMR) Adaptive Thermogenesis

Active Energy Expenditure

How much adaptive thermogenesis is accounted for in daily energy output? - ANSWER
10-15%

Which of the three components of daily total energy expenditure (TEE) has the greatest
potential for increased TEE and possible weight loss? - ANSWER Activity energy
Expenditure

Generally, energy expenditure equal to _____kcal will result in a loss of 1lb. - ANSWER
3500 kcal

This compound is made up of adenine (a carbon-nitrogen substance), ribose (a sugar),
and three inorganic phosphates and stores chemical energy from food in high-energy
bonds between the phosphates. - ANSWER Adenosine triphosphate (ATP)

__________________________ is the sum of all the energy transformation process in the
human body. - ANSWER Metabolism

This metabolic process takes place in the cytoplasm, or fluid portion, of each cell and
does not require/ use oxygen. - ANSWER Anaerobic metabolic process

This metabolic process occurs in the cell mitochondria and requires oxygen. - ANSWER
Aerobic metabolic process

___________________________ are required to burn fats. - ANSWER Carbohydrates

_______________________ is a metabolic process that may occur anaerobically or
aerobically, in which glucose or glycogen is broken down to pyruvate (aerobic) or
lactate (anaerobic) and APT is produced. - ANSWER Glycolysis

_________________________ cannot continue indefinitely, in part because the production
of lactic acid inhibits a key enzyme (phosphofructokinase) and ultimately slows down
metabolism. - ANSWER Anaerobic glycolysis

_____________________ is the aerobic metabolic process that fully breaks down
carbohydrate, fat, or protein to generate ATP, from carbon dioxide and water, and
removes hydrogen atoms for the electron transport system. - ANSWER Citric Acid Cycle

_______________________ is the final stage of aerobic energy metabolism, in which ATP is
synthesized from the energy generated in the electron transport system. - ANSWER
Oxidative phosphorylation

_________________________ is the aerobic process involving the removal of pairs of
carbon atoms from fatty acids to allow fats to enter the citric acid cycle. - ANSWER Beta
Oxidation
