NFSC 303 QUIZZSES P2 QUESTIONS AND ANSWERS
Lipolysis is a slow process during exercise, therefore the use of fats for energy during
exercise is slower than carbohydrate.
true
false - Answers - true
The body stores large amounts of ATP in the muscles.
T/F - Answers - False
Biogenetics is:
the ability to do work
the process of converting food into useful forms of energy for the body
the sum of all processes involving energy
the process of rephosphoryating ATP - Answers - B
Match the activity to the energy system that would predominate
A spring down field during a soccer match
squatting down and quickly lifting a heavy box
walking 2 miles to mcdonalds to get a burger
running around track one time
jumping up to dunk a basketball - Answers - ATP-CP or glycolysis depending on length
ATP-Cp
Krebs/ETS
Glycolysis or krebs depending on speed
atp-cp
The metabolism of one molecule of __________ can potentially, provide 100's of ATP
,Protein
Fat
creatine phosphate
carbohydrate - Answers - fat
During starvation this body produces ketones (ketone bodies) why is this important?
because ketone bodies stop the rapid breakdown of protein
Ketone bodies can be converted to glucose.
Because they can be used as a glucose alternative for brain function.
Ketone bodies allow the rate of protein degradation to slow which is important for
survival. - Answers - C and D
Large amounts of ATP are stored in the muscles
T/F - Answers - false
The primary cause of fatigue in an activity such as a marathon would most likely be
glycogen depletion
lactic acid accumalation in muscles
depletion of creatine phosphate
depletion of fat stores - Answers - glycogen depletion
The first priority for metabolism during starvation is:
Fat conservation.
Protein conservation.
Provide sufficient fat for energy production.
Provide sufficient glucose for brain and other carbohydrate dependent tissues. -
Answers - D
, The only energy system that is aerobic is glycolysis
T/F - Answers - False
Studies show that increases in muscle creatine could be achieved by supplementing the
diet with smaller doses of 3 grams per day over a longer period of time (one month) but
doses of 2 grams per day for 6 weeks showed no benefit
T/F - Answers - FALSE
Which statement about metabolism is false?
The "lag time" for fat metabolism at the beginning of exercise is shorter for trained
athletes.
Low intensity endurance exercise uses a higher percentage of fat and therefore is better
for "fat burning".
Highly trained endurance athletes metabolize fat more efficiently and to a greater
degree than untrained individuals.
There can be a 10-20 minute period of time after the onset of exercise until fat
metabolism can catch up with carbohydrate metabolism. - Answers - B low intensity....
FAD is the coenzyme form of which B vitamin?
riboflavin
vitamin c
Biotin
Niacin - Answers - riboflavin
The muscles preferentially use glycogen for energy production during exercise because:
a.
Muscle glycogen is easier to breakdown.
b.
They aren't able to pull glucose from the blood.
c.
Muscle glycogen produces more ATP than blood glucose.
Lipolysis is a slow process during exercise, therefore the use of fats for energy during
exercise is slower than carbohydrate.
