What happens to contraction of a muscle cell if some of the Ca2+ that was released during a contraction is still in the cytoplas
Kazeer [188]
<h2>Muscle contraction in cytoplasm </h2>

Explanation:

  • Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
  • ATP is basic to get ready myosin for official and to "revive" the myosin.
  • When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.

Structure moves up against epiglottis when food is swallowed to prevent passage of food into it.
borishaifa [10]

Answer:

The correct answer is A. The larynx moves up against epiglottis when food is swallowed to prevent passage of food into it.

Explanation:

The epiglottis is a moist, cartilaginous structure that is part of the cartilaginous skeleton of the larynx. It also marks the boundary between the oropharynx and the laryngopharynx. The epiglottis obstructs the passage of the bolus at the time of swallowing preventing it from going to the respiratory system.

Larynx closure occurs when the vestibular and vocal folds approach the midline during swallowing. Occasionally, when you eat very fast, solid foods or liquids can enter the larynx.
