Question

In small intestine the concentrated of the glucose and salt is low
In the above situation which process is required for the absorption of molecules
Write 2 peculiarities of this process

Answer 1

The small intestine is the site of most chemical digestion and almost all absorption. Chemical digestion breaks large food molecules down into their chemical building blocks, which can then be absorbed through the intestinal wall and into the general circulation.

peculiarities of chemical digestion:--

1- it is more specific than mechanical digestion. Typically, enzymes only work on one substance; for example, salivary amylase only works on carbohydrates. Mechanical digestion, such as maceration, however, will break all food down evenly.

2-macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body.
