Straighterline Nutrition Final exam
Flashcards 2026 |ACTUAL EXAMS |A+
GRADED 100 % VERIFIED ANSWERS!!!
physical fitness - <<<<Answers>>>>the ability to perform
moderate to vigorous activity without undue fatigue
,ATP (adenosine triphosphate) - <<<<Answers>>>>the
main energy currency for cells. Used to promote ion
pumping, enzyme activity, and muscular contraction. The
immediate source of energy for body functions.
ADP (adenosine diphosphate) - <<<<Answers>>>>A
breakdown product of ATP. Synthesized into ATP using
energy from foodstuffs and a phosphate group.
phosphocreatine (PCr) - <<<<Answers>>>>A high-energy
compound that can be used to re-form ATP. It is used
primarily during bursts of activity, such as lifting and
jumping.
creatine - <<<<Answers>>>>An organic (i.e. carbon
containing) molecule in muscle cells that serves as a part
of a high-energy compound (termed creatingphosphate or
phosphocreatine) cable of synthesizing ATP from ADP.
The primary goal in the use of any fuel (carb, fat, protein) -
<<<<Answers>>>>to make ATP.
First line of defense for resupplying ATP in muscles -
<<<<Answers>>>>PCr (phosphocreating)
The main advantage of phosphocreatine -
<<<<Answers>>>>It can be activated instantly and can
replenish ATP at rates fast enough to meet the energy
demands of the fastest and most powerful actions.
,Disadvantage of phosphocreatine - <<<<Answers>>>>Not
much of it is made and stored in the muscles
Ues of glucose to make ATP can be either __ or __ -
<<<<Answers>>>>anaerobic or aerobic
Anaerobic glucose breakdown - <<<<Answers>>>>yields
energy fast. It provides most of the energy needed for
events that require a quick burst of energy (sprints)
Disadvantage of the anaerobic breakdown of glucose -
<<<<Answers>>>>(1) cannot be sustained for long
periods of time and (2) the rapid accumulation of lactic
acid greatly increases the acidity of the muscle.
pyruvic acid - <<<<Answers>>>>a three-carbon
compound formed during glucose metabolism, also called
pyruvate
lactic acid - <<<<Answers>>>>A three-carbon acid formed
during anaerobic cell metabolism; a partial breakdown
product of glucose; also called lactate.
Aerobic glucose breakdown is a ___ energy source -
<<<<Answers>>>>sustained
aerobic breakdown of glucose yields approximately __
percent of the ATP made from complete glucose
metabolism - <<<<Answers>>>>95%.
, Products of aerobic glucose breakdown -
<<<<Answers>>>>carbon dioxide and water as opposed
to the lactic acid of anaerobic glucose breakdown
bonking - <<<<Answers>>>>diminished mental ability as
the result of blood glucose declining during exercise
Fall in blood glucose during exercise is related to the
depletion of ____ glycogen - <<<<Answers>>>>liver (not
muscle0
____ glycogen is used to maintain blood glucose -
<<<<Answers>>>>liver
what is the main fuel for prolonged low-intensity activity -
<<<<Answers>>>>fat
for lengthy activities at a moderate pace, fat supplies how
much of the energy required? - <<<<Answers>>>>70-90%
The only fast-paced anaerobic fuel we eat is -
<<<<Answers>>>>carbohydrate
Slow and steady aerobid activity uses___ in addition to
___ - <<<<Answers>>>>fat/carbohydrateq
amino acids derived from protein only supply about ___ of
the body's general energy needs. - <<<<Answers>>>>5%.
10-15% during endurance exercise.
