Question

question 16
the building of a large organic molecule from small subunits involves multiple ________.
osmotic reactions
synthesis reactions
decomposition reactions
hydrolysis reactions

Explanation:

• Osmotic reactions involve the movement of water across a semi - permeable membrane, not building molecules.
• Synthesis reactions combine small subunits (monomers) to form large molecules (polymers). For example, amino acids (subunits) combine via synthesis reactions (peptide bond formation) to form proteins (large organic molecules).
• Decomposition reactions break down large molecules into smaller ones.
• Hydrolysis reactions use water to break bonds in large molecules, which is the opposite of building them.

Answer:

B. synthesis reactions
