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.
Answer:
False
Explanation:
Stem cells are different type of cells in human body that can develop into different other body cells like muscles cells or brain cells and they gave the capability to renew themselves through mitotic cell division.
Stem cells are not lost in childhood but can be use to treat diseases or infection, it can be use to grow new cells and replace damaged body cells.
