Question

What happens to a piece of bread as it moves from the mouth to the anus?
Indicate what happens at each stage and the enzymes involved.​

Answer 1

Answer:

process begins in preparation for that first bite

enters the mouth

passes through a long tube

exits the body as feces (poop) through the anus

Along the way, food is broken down into tiny molecules so that the body can absorb nutrients it needs:

Protein must be broken down into amino acids.

Starches break down into simple sugars.

Fats break down into into fatty acids and glycerol.

The waste parts of food that the body can't use are what leave the body as feces.
