Answer:
The reactions that are condensation reactions are:
- Deoxyribonucleic acid → five-carbon sugar + phosphate group + nitrogen base
- Glucose + fructose → sucrose
- Lysine (amino acid) + serine (amino acid) + glycine (amino acid) → polypeptide
Step-by-step explanation:
In a condensation reaction, two molecules combine to form a larger molecule, and a smaller molecule, such as water, is released as a by-product.
