Question

15. Your buffer systems have been activated, which of the following would be true?

1. They work in milliseconds but do not remove the problem.
2. They change strong acids/bases into weak acids/bases
3. Compensatory mechanisms include breathing and/or urinating to rid the body of the excess
4. All of the above are true concerning buffer systems.
5. A & C are true concerning buffer systems.

Answer 1

Answer 15:) Option d

The biological buffer systems include phosphate, plasma proteins, and carbonic acid and bicarbonate buffers. These are able to control acid-base balance. The reaction by buffers is quick such as the carbonic acid conversion to CO2 and water is too fast. Therefore, this buffer system can change pH within milliseconds. The change in pH also controls by changing breathing and/or urinating such as hyperventilation during respiratory alkalosis. Therefore, all options are correct.
