DH209 NUTRITION Q2 EXAM 57 QUESTIONS
WITH VERIFIED ANSWERS 2026
a. Both the statement and the reason are correct and related.
Both the statement and the reason are correct and related. Prescription enzymes
are more likely to have protective features which prevent the active ingredient
from being digested prior to the point at which it can be used. For example,
prescription pancreatic enzymes have a special enteric coating preventing the
enzyme from exposure to gastric juices. An example of an OTC product that has
such a protective feature is lactase which is effective for lactose intolerant because
it is either added to or taken with lactose-containing foods. - CORRECT ANSWER
The use of over-the-counter enzyme tablets might not be beneficial to patients
because the enzymes within the product are digested before they can be used.
a. Both the statement and the reason are correct and related.
b. Both the statement and the reason are correct but are not related.
c. The statement is correct, but the reason is not correct.
d. The statement is not correct, but the reason is correct.
a. Salivary amylase
Some chemical action or hydrolysis of nutrients begins in the mouth. Salivary
amylase initiates starch digestion. If a carbohydrate, such as a cracker, is chewed
and held in the mouth for a few seconds, it will begin to taste sweet. This denotes
that some of the starch is being hydrolyzed to dextrin and maltose. Note that the
name for many enzymes is derived from the name of its substrate, with the suffix -
,as. Sucrase is the enzyme that hydrolyzes sucrose. - CORRECT ANSWER Hydrolysis
of a starch begins with which enzyme?
a. Salivary amylase
b. Pepsin
c. Pancreatic amylase
d. Sucrase
b. Enzymes regulate metabolic reactions so that they proceed slowly and
thoroughly.
Enzymes enable metabolic reactions to proceed at a faster rate without being
exhausted. Enzymes function similar to keys: they are highly specific and function
on only one substrate, similar to a key fitting a particular lock. When the reaction
is completed, the complex separates, releasing new chemical compounds and the
enzyme. - CORRECT ANSWER Each is true of enzymes, except one. Which is the
exception?
a. Enzymes are complex proteins that are very specific.
b. Enzymes regulate metabolic reactions so that they proceed slowly and
thoroughly.
c. Enzymatic reactions require a substrate.
d. Only small amounts of an enzyme is needed to complete a reaction.
, c. The first statement is true; the second is false.
The first statement is true; the second is false. Amoxicillin undoubtedly has other
food-drug interactions, but it is tetracycline that interacts with milk and milk
products. The result of this interaction is that lowered amounts of tetracycline and
calcium are available to the body. - CORRECT ANSWER Food-drug interactions
have the potential to cause nutritional problems. For example, consuming milk or
milk products while taking amoxicillin decreases the amount of antibiotic and
calcium available to the body.
a. Both statements are true.
b. Both statements are false.
c. The first statement is true; the second is false.
d. The first statement is false; the second is true.
c. Enzymatic breakdown of cellulose
Cellulose, a carbohydrate found in plants, cannot be completely digested because
the human body lacks enzymes that can hydrolyze and break it down. - CORRECT
ANSWER Each statement describes functions of the small intestine, except one.
Which is the exception?
a. Complete hydrolysis of most energy-providing nutrients
b. Absorption of most vitamins and minerals
c. Enzymatic breakdown of cellulose
