Page: 137
Difficulty:


Useful protein drugs, such as insulin, must still be administered by the cumbersome procedure of injection under the skin. If proteins are taken orally, they are digested and cannot reach their target cells. Certain nonprotein drugs, however, contain chemical bonds that are not broken down by the digestive system. They can, thus, be taken orally.

The statements above most strongly support a claim that a research procedure that successfully accomplishes which of the following would be beneficial to users of protein drugs?

(A) Coating insulin with compounds that are broken down by target cells, but whose chemical bonds are resistant to digestion
(B) Converting into protein compounds, by procedures that work in the laboratory, the nonprotein drugs that resist digestion
(C) Removing permanently from the digestive system any substances that digest proteins
(D) Determining, in a systematic way, what enzymes and bacteria are present in the normal digestive system and whether they tend to be broken down within the body
(E) Determining the amount of time each nonprotein drug takes to reach its target cells.


[Reveal] Spoiler:
A and B are confusing, anybody a clear explanation? pls~?

Clearly A.

The problem with B is that it dealing with other drugs , which, even after being converted into protein compound could or could not help the users of protein drugs. Moreover, may be after being converted into protein compounds, those drugs will be digested as well.

A is surely going to benefit as proteins can be taken orally. The other options are either not related or not practical.

B - does just the opposite of what we want to get done via research
C - Bad idea :)
D - not related
E - not related

BCDE are all irrelevant to the core. A stands out clearly.

A should be the answer. It tackles the problem of protein drugs (insulin) being broken down by the digestive system.

A is the correct choice.

A and B are different.
B says a procedure that will convert the non-protein into protein. Scientificaly if it is non-protein it is non-protein. For example, you cannot convert carbohydrates to protein.

A. Coating insulin with compounds that are broken down by target cells, but whose chemical bonds are resistant to digestion. [Hold]
B. Converting into protein compounds, by procedures that work in laboratory, the nonprotein drugs that resist digestion. [Defeats the purpose of the protein drug]
C. Removing permanently from the digestive system any substances that digest proteins [removing cells from the digestive system - ?]
D. Determining, in a systematic way, that ensymes and bacteria are present in the normal digestive system and whether they tend to be broken down within the body. [ensymes and bacteria are present – not even discussed]
E. Determining the amount of time each nonprotein drug takes to reach its target cells. [not helps in digesting protein]

A!

Yep! another A

Coating prevents digestion and helps reach target cells, which then break it up

Removing permanently from the digestive system any substances that digest proteins is harmful to the body itself. It won't be logical.

C. Removing permanently from the digestive system any substances that digest proteins

This does not benefit the users of protein drugs. Actually, it may be detrimental.

The statements above most strongly support a claim that a research procedure that successfully accomplishes which of the following would be beneficial to users of protein drugs?
