When we ingest large molecules such as lipids, carbohydrates, and proteins, they must undergo catabolic reactions whereby enzymes split these molecules. This series of reactions is called ________.
A) absorption
B) secretion
C) chemical digestion
D) mechanical digestion

Question

Quizplus · Accepted Answer

The process described in the question refers to the breaking down of large molecules into smaller ones during digestion, which is called chemical digestion. Absorption refers to the movement of nutrients from the digestive tract into the bloodstream or lymphatic system, secretion refers to the release of digestive enzymes and other substances by glands or cells, and mechanical digestion refers to the physical breakdown of food (e.g. chewing, churning in the stomach).
