NEETBotanyBiomolecules (B)
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Lecithin is classified as a phospholipid and is found in cell membranes. Reason (R): The structure of lecithin contains phosphorus and a phosphorylated organic compound. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
Step-by-step solution
Assertion (A) is correct because lecithin is a well-known example of a phospholipid that serves as a key structural component of cell membranes. Reason (R) is correct because phospholipids are defined chemically by the presence of phosphorus and a phosphorylated organic compound in their structure. Since the presence of the phosphorylated organic compound is the exact chemical basis for classifying lecithin as a phospholipid, (R) provides the correct explanation for (A). Answer: Both (A) and (R) are correct and (R)
