Answer:
B. In skeletal muscle, calcium initiates contraction by binding to troponin, while in smooth muscle calcium initiates contraction by binding to calmodulin.
Explanation:
The Calcium ions (Ca2 +) have a key role in skeletal muscle contraction. Moreover, the Troponins are regulatory proteins that also play roles in skeletal contraction. In this muscle, troponin is attached to tropomyosin, when Ca2 + binds to troponin it induces a conformational change, thereby exposing this protein to its binding to myosin filaments on the actin filaments, which initiates muscle contraction.
On the other hand, calmodulin (calcium-modulated protein) is a protein which mediates the contractile state of the smooth muscle by binding Ca2+ ions. The function of this protein is to stimulate the development of force (contraction) in response to Ca2+ ions by activating the phosphorylation of myosin.
The best response that the nurse should provide to the
client is advising her, the disadvantage of not having to follow the doctor’s
request of having a surgery and using alternatives just to manage the illness
that she acquires. The nurse would likely suggest that the client’s management
would cause risk in having her kidney to be damaged. The cystocele that the client
is experiencing causes weakening of pelvic structures, there will be a cause of
urinary stasis and the bladder will not be as empty as it supposed to be when
urinating. A surgery is important when a person has this illness for it
prevents chronic infection that would likely happen and even renal failure. The
surgery would prevent complications and improve the person’s bladder functions.
