NFSC 303 Quizzses p2 Questions and Answers Latest Update 2025-2026
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....
