Question

To actually enter the body, a substance must cross a cell membrane. During which stage of food processing does this first happen?

A. digestion

B. ingestion

C. elimination

D. absorption

E. hydrolysis

Answer 1

D

Answer 2

D is the corect answer.

a--digestion is when the food breaks down in your stomach

b--ingestion is when the food is eaten

c-elimination is when theremainder of the food is excreted

D-absorption is when the nutrients of the food is absorbed through cell membranes

e--hydrolysis has nothing to do with this

Answer 3

its during absorption dear that the complex sunstances enter the cell membrane after being broken into simpler molecules...high molecular weight compounds cannot cross cell membrane so the whole process of chewing and the churning of the food in stomach,i.e., digestion takes place to reduce these high molecular weight compounds to low molecular weight compounds so they can cross cell membrane......
