Question

which of these molecules needs to be emulsified before digestion begins? a protein b sugar c fat d all apply.

Explanation:

Emulsification is a process that breaks down large fat globules into smaller droplets to increase the surface area for enzymatic action. Proteins are digested by proteases, and sugars (carbohydrates) are digested by carbohydrases without the need for emulsification. Only fats require emulsification (by bile) before digestion.

Answer:

C. Fat
