An isotonic contraction is described as Select one:
• action potential frequency is high enough that no relaxation of muscle
fibersoccurs.
• a muscle produces constant tension during contraction.
• a muscle produces an increasing tension during contraction.
• a muscle produces increasing tension as it shortens.
• a muscle produces tension, but the length of the muscle is increasing -
✔✔b. amuscle produces constant tension during contraction.
After contraction has occurred, the calcium isSelect one:
,• destroyed by cholinesterase.
• chemically bound to the cross bridges.
• secreted by the Golgi apparatus to the outside of the cell.
• released from troponin.
• returned to the sarcolemma. - ✔✔d. released from troponin.
