AEmulsification of large lipid globules
BDeamination of surplus amino acids
CPropulsion of food along the canal
DFiltration of plasma at the kidney
Answer & Solution
Correct answer: C. Propulsion of food along the canal
1. The six activities of digestion are ingestion, propulsion, mechanical digestion, chemical digestion, absorption and defecation.
2. Propulsion, the movement of food through the tract, appears on that list, so it is the answer.
3. Emulsification is one step within lipid digestion, not one of the six headline processes.
4. Deamination and plasma filtration belong to liver metabolism and kidney function respectively.
