Multiple Choice
What relation do indigestible plant fibers, prokaryotes, and vitamins have with the digestive system?
A
They are washed out of the body in water that daily passes into the digestive system.
B
In the presence of certain vitamins, prokaryotes are able to digest plant fibers.
C
The bacteria cause rapid peristalsis, resulting in constipation, which retains plant fibers and vitamins in the lower intestine.
D
They move through the terminal portion of the colon together and are voided as feces.
E
They are the contents of the large intestine.
Verified step by step guidance
1
Understand that the digestive system is responsible for breaking down food, absorbing nutrients, and eliminating waste.
Recognize that indigestible plant fibers, prokaryotes (bacteria), and vitamins are all components that interact within the digestive system, particularly in the large intestine.
Indigestible plant fibers, such as cellulose, are not broken down by human digestive enzymes and thus pass into the large intestine.
Prokaryotes, or gut bacteria, reside in the large intestine and play a role in breaking down some of these fibers, producing gases and short-chain fatty acids in the process.
Vitamins, particularly those produced by gut bacteria (like vitamin K and some B vitamins), are absorbed in the large intestine, while the remaining indigestible fibers, bacteria, and unabsorbed vitamins are eventually excreted as feces.
