Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Minerals are inorganic elements essential for diverse structural and physiological processes, including skeletal tissue formation, osmotic regulation, and enzyme activation.
Step 2: Detailed Explanation:
Calcium (\(\text{Ca}^{2+}\)) is a crucial divalent cation that acts as a key physiological regulator:
- Blood clotting: It is essential for the enzymatic activation of clotting factors (acting as Factor IV in the coagulation cascade).
- Muscle function: It binds to troponin, exposing the actin-myosin binding sites to initiate muscle contraction.
- Nerve impulse transmission: Calcium influx into presynaptic nerve terminals triggers the release of neurotransmitters into the synaptic cleft.
Step 3: Final Answer:
The element that plays these key roles is Calcium, corresponding to option (D).
