pH is a measurement of the:
|
hydroxide ion concentration of a solution and the amount of buffer needed in a solution
|
|
|
A solution with a pH of 9.0 would:
|
have fewer hydrogen ions than hydroxide ions
|
|
|
A solution with a pH of 7.0 would:
|
be a neutral solution
|
|
|
What mechanism is used by the body to regulate body pH?
|
- the buffer system
- the respiratory mechanism - the urinary mechanism |
|
|
The enzyme that converts dioxide and water to carbonic acid is:
|
carbonic anhydrase
|
|
|
Metabolism tends to add:
|
more acids than bases to the blood
|
|
|
Strong acids tend to:
|
drastically lower the pH
|
|
|
When the carbonic acid-sodium bicarbonate buffer pair buffer an acid:
|
the pH of the blood drops slightly
|
|
|
When the carbonic acid-sodium bicarbonate buffer pair buffer a base:
|
- water is produced
- the pH rises less than it would if there were no buffer system |
|
|
A decrease in respiration rate:
|
- increases the carbonic acid in the blood
- causes a drop in blood pH |
|
|
The most effective regulator of blood pH is the:
|
urinary system
|
|
|
When the kidney secretes hydrogen ions:
|
the pH of the urine drops
|
|
|
The kidney also can acidify the urine by:
|
converting an amino acid group to ammonia
|
|
|
Alkalosis occurs when the:
|
blood pH rises
|
|
|
Patients with a bicarbonate deficit experience:
|
metabolic acidosis
|
|
|
Excessive vomiting results in a massive loss of HCl and:
|
metabolic alkalosis
|
