Answer:
The correct answer will be option-D.
Explanation:
Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.
Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.
This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.
Thus, option-D is the correct answer.

Answer:
The options
a. riboflavin
b. vitamin D
c. pantothenic acid
d. folic acid
The CORRECT ANSWER IS d.
d. Folic acid
Explanation:
Having a healthy baby means staying healthy. Getting sufficient folic acid each day — mostly before conception and at early pregnancy as it reduces risk of serious neural tube defects (partial development of the brain and spinal cord) to a very large extent.
Folic acid (or folate) is a B vitamin (B9) found majorly in dark green vegetables (broccoli and spinach), legumes(beans and peas) and enriched grains.
It is essential for all women of childbearing age to get sufficient folic acid (necessary for cell growth and development plus DNA formation too)— not just those who are trying to conceive.
