1 FINAL PAPER 2026 TESTED QUESTIONS WITH
FULL SOLUTION GRADED A+
◉ Which of the following events occurs on the postsynaptic
membrane?
Select one:
a. acetylcholine production
b. rapid degradation of acetylcholine
c. release of neurotransmitter
d. neurotransmitter combines with a receptor molecule
e. release of calcium ions. Answer: d. neurotransmitter combines
with a receptor molecule
◉ The sarcoplasmic reticulum
Select one:
a. stores calcium ions.
b. shortens during muscle contraction.
c. transmits nerve impulses to the myofibrils.
d. connects adjacent sarcomeres.
,e. covers the muscle fiber.. Answer: a. stores calcium ions.
◉ After contraction has occurred, the calcium is
Select one:
a. destroyed by cholinesterase.
b. chemically bound to the cross bridges.
c. secreted by the Golgi apparatus to the outside of the cell.
d. released from troponin.
e. returned to the sarcolemma.. Answer: d. released from troponin.
Correct
◉ An isotonic contraction is described as
Select one:
a. action potential frequency is high enough that no relaxation of
muscle fibers occurs.
b. a muscle produces constant tension during contraction.
c. a muscle produces an increasing tension during contraction.
d. a muscle produces increasing tension as it shortens.
e. a muscle produces tension, but the length of the muscle is
increasing.. Answer: b. a muscle produces constant tension during
contraction.
,◉ Which of the following is true?
Select one:
a. Muscle fatigue has no influence on the force of contractions.
b. A threshold stimulus will cause contraction of a muscle fiber.
c. A subthreshold stimulus causes a muscle contraction.
d. Motor units do not obey the "all or none" law.
e. A threshold stimulus will not affect motor units.. Answer: b. A
threshold stimulus will cause contraction of a muscle fiber.
◉ The elevated oxygen consumption relative to activity level after
exercise has ended is called
Select one:
a. oxygen deficit.
b. oxygen debt.
c. oxygen repayment.
d. recovery oxygen consumption.
e. anaerobic recovery.. Answer: d. recovery oxygen consumption.
Correct
, ◉ When skeletal muscle is producing carbon dioxide and water
while making ATP, which chemical processes could be active at this
time?
Select one:
a. anaerobic respiration
b. aerobic respiration
c. both anaerobic and aerobic respiration. Answer: b. aerobic
respiration
◉ What is anaerobic respiration?. Answer: Anaerobic respiration is
the release of energy from glucose without using oxygen. This
produces lactic acid; Respiration without oxygen.
◉ What is aerobic respiration?. Answer: Aerobic respiration uses
oxygen from the air to release energy from glucose; Respiration with
oxygen.
◉ Which of the following is NOT an age related change in skeletal
muscle?
Select one:
a. loss of muscle strength
b. loss of synapse surface area
