Small molecular subunits called ______ form chemical bonds to make larger polymers.

• A. nucleotides
• B. monomers
• C. isomers
• D. enzymes

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the concept of monomers and polymers. Monomers are small molecular subunits that can chemically bond together to form larger molecules called polymers. For example, glucose (a monomer) can bond to form starch (a polymer).
2. Step 2: Review the options provided in the question: nucleotides, monomers, isomers, and enzymes. Determine which term best fits the definition of small molecular subunits that form chemical bonds to create larger polymers.
3. Step 3: Eliminate incorrect options by understanding their definitions: - Nucleotides are specific monomers that form nucleic acids like DNA and RNA, but they are not a general term for all small subunits. - Isomers are molecules with the same chemical formula but different structures, unrelated to forming polymers. - Enzymes are proteins that catalyze chemical reactions, not structural subunits.
4. Step 4: Recognize that 'monomers' is the correct term because it is the general name for small molecular subunits that bond to form polymers.
5. Step 5: Conclude that the correct answer is 'monomers,' as it matches the definition provided in the question.
