In a basic environment, the carboxyl end of a protein can release hydrogen ions to counteract the change in ph.
a. true
b. false

False.

Explanation:

Zwitter ion may be defined as the molecule that contains the net neutral charge. The change in pH can change the charge on the zwitter ions. Amino acids can exist in the form of zwitter ions.

The basic environment, causes the deprotonation of the ammonia group. The carboxyl end of a protein release the hydrogen ions in the acidic environment , not in the basic environment.

Thus, the answer is false.

probably since the potency of the cocaine, not a lot, but i've never done any research on cocaine so i wouldn't know, but i would also guess it would determine on the gap between sniffs or if you did it all at once, so i really don't know.
