Question

question 3
which of the following statements about digestion is false?
a digestion is the process of breaking food into absorbable components.
b most digestion occurs in the mouth.
c there are two main types of digestion: mechanical and chemical.
d the rate at which food travels through the digestive tract can depend, to some extent, on the composition of the food or meal.

Explanation:

Digestion is the process of breaking food into absorbable components. There are two main types of digestion: mechanical (e.g., chewing) and chemical (e.g., action of enzymes). Digestion in the mouth involves both mechanical (chewing) and chemical (salivary amylase acting on starch) processes. The rate at which food travels through the digestive tract is mainly regulated by factors like peristalsis, not significantly by food composition (unlike some claims in option D).

Answer:

D. The rate at which food travels through the digestive tract can depend, to some extent, on the composition of the food or meal.
