Question

Quizplus · Accepted Answer

Only fat molecules require emulsification before digestion begins. This is because fat molecules are hydrophobic (water-repelling) and do not mix well with the watery environment of the digestive system. Emulsification breaks up large fat droplets into smaller ones, which can mix with digestive enzymes and be broken down more effectively. Proteins and sugars do not need to be emulsified before digestion can begin as they are already soluble in water.
