the food that we ingest typically contains what?

polymers, which are too large to be used by the cells of the body
because polymers are to large to be used by the cells of the body, what needs to happen?

the polymers in food must first be broken down into monomers that are small enough to be taken up by cells and then used for energy
definition of digestion,

The process by which the polymers in food are broken down into their constituent monomers
digestion involves what kind of enzymes and what do they do?

Digestion involves digestive enzymes that catabolize (break down) the polymers in the food in the lumen of the digestive tract
(finish the sentence) (digestion)
As the monomers are released, they are absorbed from the....

he lumen of the digestive tract into the blood and then transported to the cells in the rest of the body.
(finish the sentence) (digestion)
Once inside of the cells, what do monomers do?
how does it happen?

monomers are further broken down via the process of cellular (aerobic) respiration in order to provide ATP as the energy source for different cellular activities
