Question

multiple choice question
what is a monomer?
a small repeating molecular unit in a polymer chain
the smallest unit characteristic of a carbohydrate
a form of long - term storage for energy
a type of macromolecule

Explanation:

Brief Explanations

To determine the correct answer, we analyze each option:

  • Option 1: A monomer is defined as a small repeating molecular unit that makes up a polymer chain (polymers are made by linking monomers).
  • Option 2: The smallest unit of a carbohydrate is not a monomer in the general sense (monomers apply to various polymers like proteins, nucleic acids, etc., not just carbohydrates in this specific way).
  • Option 3: Long - term energy storage (e.g., fat) is not what a monomer is.
  • Option 4: Macromolecules are made of monomers, so a monomer is not a macromolecule itself.

Answer:

A. A small repeating molecular unit in a polymer chain
