BIOL 2401 Exam 4 Questions | 2026/2027 | Answers Correct
| With Complete Solutions
A band Correct Answers a dark region within a sarcomere that
contains thick myosin filaments and some thin actin filaments
Acetylcholine Correct Answers A chemical neurotransmitter in
the brain and peripheral nervous system; released at
neuromuscular junction, and synapses of the parasympathetic
division
Acetylcholinesterase enzyme Correct Answers An enzyme
found in the synaptic cleft, bound to the post synaptic membrane
and in tissue fluids; breaks down and inactivates acetylcholine
molecules
Agonist (prime mover) Correct Answers A muscle responsible
for specific movement
Antagonist Correct Answers A muscle, that opposes the
movement of an agonist
Aponeurosis Correct Answers Broad tendinous sheet that may
serve as the origin or insertion of a skeletal muscle
Appendicular Correct Answers Muscles of the arms and legs
ATP production during muscle contraction: Cori cycle Correct
Answers Skeletal muscles break down glucose to form pyruvate
and ATP and use ATP as energy
, ATP production during muscle contraction: moderate activity
Correct Answers aerobic respiration within the mitochondria
ATP production during muscle contraction: resting muscle
Correct Answers aerobic respiration within the mitochondria
ATP production during muscle contraction: role of oxygen
Correct Answers enabling aerobic respiration
ATP production during muscle contraction: sustained activity
Correct Answers ATP needs to be regenerated at a rate
complementary to ATP demand
Axial Correct Answers Muscles of the head neck abdomin
chest and pelvis
Belly of muscle Correct Answers the thickest or largest part of
a muscle
