Type of digestion that is not helpful in direct absorption of food:
Correct answer: A. Mechinical
- A. Mechinical
- B. Biochemical
- C. Chemical
- D. Enzymatic
Explanation
Therefore, the correct answer is A) Mechanical, as mechanical digestion does not directly aid in the absorption of food. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion. The role of chemical digestion is to further degrade the molecular structure of the ingested compounds by digestive enzymes into a form that is absorbable into the bloodstream.
