Which of the following is involved in digestion? water bile bicarbonate all of these
ALL OF THESE
Which of the following can act on the terminal end of a peptide?
Aminopeptidase and Carboxypeptidase
Which of the following can be absorbed in the intestinal villi by facilitated diffusion? Galactose Sucrose Glucose Fructose
FRUCTOSE
The suffix -ase is used to identify
enzyme
Chylomicrons are released from epithelial cells in the intestines through
exocytosis
Lipids are typically transported from the intestine into the bloodstream via
lacteals.
Protein digestion begins in the stomach and ends in the small intestine.
t
Bile salts convert fats into
tiny droplets.
Pancreatic juice contains all of the following except chymotrypsin trypsin. pepsin. carboxypeptidase.
PEPSIN
Aminopeptidase and Dipeptidase are found in the brush border epithelium.
T
Amylases can catalyze the breakdown of more starch and glycogen.
T
Carbohydrate digestion begins in the mouth and ends in the small intestine.
T
Carboxypeptidase breaks the bond between the terminal amino acids on the carboxy end of the peptide.
T
Cellulose is an indigestible carbohydrate by the enzymes of the human body.
T
Digestion requires chemical and mechanical breakdown of nutrients.
T
Dipeptidase breaks down dipeptides.
T
Lipase breaks down triglycerides into monoglycerides and fatty acids.
T
Lipases break down triglycerides and phospholipids.
T
Pancreatic lipase is the main lipid digesting enzyme in the body.
T
Pepsin is a gastric enzyme that initiates protein digestion.
T
Salivary amylase only has a short time to digest carbohydrates because it is destroyed in the stomach.
T
The primary function of the digestive system is to process food into absorbable molecules.
T
Water is the primary component of most foods. It is also essential to proper digestion.
T
Acids are produced by the stomach and intestines.
F
Active transport proteins are required for the absorption of fatty acids by epithelial cells.
F
Aminopeptidase breaks the bond between the terminal amino acids on the carboxy end of the peptide.
F
Bile salts cause fat globules to merge together into larger droplets.
F
Digestion is primarily based on dehydration reactions.
F
Pepsinogen is converted into pepsin due to
