Assertion and Reasoning Questions:
Assertion: Calcium helps in neuromuscular function.
Reason: All Calcium passes through the plasma.
Explanation:
• Calcium is an essential mineral required for various biological functions in the human body.
• It plays a key role in muscle contraction, including the contraction of the heart muscles, and is also important for nerve impulse conduction.
• The level of calcium ions in the blood plasma is tightly regulated to maintain the normal functioning of cells and tissues.
• Calcium ions are transported across cell membranes by specialized proteins known as ion channels and pumps.
• The calcium ions that enter the cells during muscle contraction are also transported back to the extracellular fluid by these channels and pumps.
• Therefore, it is not true that all calcium passes through the plasma.
• The assertion is true, but the reason is not the correct explanation for it.
• Hence, option (B) is the correct answer.
Key Points:
• Calcium is essential for neuromuscular function.
• Calcium ions are transported across cell membranes by specialized proteins.
• The level of calcium ions in the blood plasma is tightly regulated.
• The reason given in the question is not correct.
