BIO 168 FINAL PAPER 2026 COMPLETE
QUESTIONS WITH SOLUTIONS
◉inadequate release of calcium ions from the sarcoplasmic
reticulum
depletion of creatine phosphate
insufficient oxygen, nutrient depletion, lactic acid and ADP build up.
Answer: Which of the following contribute to muscle fatigue?
◉true. Answer: Recovery oxygen uptake better describes the
elevated use of oxygen after exercise than the term oxygen debt.
◉a large number of small motor units. Answer: Whole muscles that
control precise movements consist of:
◉true. Answer: In motor unit recruitment, the number of active
motor units increases.
, ◉true. Answer: Muscle tone keeps muscles firm but does not
produce enough force to cause movement.
◉Isometric contractions result in lengthening or shortening of the
muscle and moving a load E large motor unit.. Answer: Which of the
following statements is INCORRECT?
◉eccentric isotonic. Answer: On the first day of summer vacation,
Preston hiked four miles up a steep mountain trail. The following
day his calf muscles were sore. What type of contraction did walking
up the mountain trail involve?
◉the speed of the myosin ATPase. Answer: Skeletal muscle fibers
are classified as "fast" or "slow" based upon what factor?
◉slow oxidative, fast-oxidative glycolytic, fast glycolytic. Answer: As
Marie rounded the corner, she saw that people were already
boarding her bus. Worried that she would miss her ride to campus,
she sprinted to the bus stop. In what order were skeletal muscles
recruited during her sprint?
◉increased synthesis of thick and thin filaments. Answer: On a
cellular level, what causes muscle hypertrophy?
◉presence of intercalated disks
