Exam 33: Acid-Base Balance

If a strong acid were added to the phosphate buffer pair,the amount of Na₂HPO₄ in the solution would increase.

Why does arterial blood have a lower hydrogen ion concentration than venous blood?

Carbonic anhydrase is an enzyme necessary for the formation of carbonic acid in the kidney tubules.

In acidosis,the renal tubule excretion of hydrogen ions:

Which of the following would be important in treating metabolic alkalosis?

An increase in the base bicarbonate/carbonic acid ratio causes a decrease in the pH.

Name and explain the two types of pH control mechanisms used by the body.

The numerical value of pH represents the:

For the bicarbonate buffer system to function,both the absolute amount and the ratio of the components must remain constant.

The reason a change in pH damages an enzyme's ability to function is that it changes the shape of the enzyme.

Prolonged hyperventilation tends to:

Under normal body conditions,the chemical buffer system can maintain normal body pH.

If NaOH were buffered by H-HCO₃,what would occur?

Sulfuric acid results from the metabolism of:

When NaOH is added to a buffered solution,one of the substances produced is water.

For the body to maintain an acid-base balance,which of the following is(are)necessary?

Which of the following is(are)classified as an acid-forming food?

Kidney tubule base bicarbonate reabsorption and hydrogen ion excretion both tend to alkalinize the blood by acidifying the urine.

When the renal tubules reabsorb sodium ions,they normally exchange (secrete)which of the following?

The metabolism of ribonucleotides increases the hydrogen ion concentration of intracellular fluid.
