NEETBotanyBiomolecules (B)
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Insulin, trypsin, and GLUT-4 are proteins that perform diverse functions in the body. Reason (R): Proteins are homopolymers consisting of a single type of amino acid monomer. In the light of the above statements, choose the correct answer from the options given below.
Options
- ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
- BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
- CAssertion (A) is true but Reason (R) is false
- DAssertion (A) is false but Reason (R) is true
Correct answer
C. Assertion (A) is true but Reason (R) is false
Step-by-step solution
Assertion (A) is true because insulin acts as a hormone, trypsin acts as an enzyme, and GLUT-4 enables glucose transport into cells. All of these are diverse functional proteins. Reason (R) is false because proteins are heteropolymers, not homopolymers. They are formed by the linking of up to 20 different types of amino acids, whereas a homopolymer consists of only one type of monomer repeating 'n' number of times. Answer: Assertion (A) is true but Reason (R) is false
