Kin 335 Chap 4 Exam Study Set
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
