Exam 33: Acid-Base Balance

The more hydrogen ions excreted by the renal tubules,the:

Kidney tubule base bicarbonate reabsorption and hydrogen ion excretion both tend to:

In clinical medicine,acidosis can occur when the arterial blood is still basic.

Direct acid-forming foods contain acids that cannot be metabolized.

Match each term with it corresponding definition. -process that allows carbon dioxide to be buffered in the RBC and then carried as bicarbonate in the plasma

Bicarbonate loading can lead to metabolic acidosis and disastrous effects if used long-term.

An example of a physiological buffer system (with a delayed response time)would be the _____ system.

On the pH scale,as the value moves from 1 toward 7,the concentration of hydrogen ions increases.

Both the distal tubule cells and the red blood cells use carbonic anhydrase to help combine carbon dioxide and water.

The breakdown of ribonucleotides produces phosphoric acid.

Match each term with it corresponding definition. -any substance that decreases the amount of the hydrogen ion concentration in a solution

The respiratory center becomes stimulated if the:

The biological activity of phosphofructokinase (an important enzyme in anaerobic respiration)falls by 90% if the pH:

Which of these is true about the metabolism of glucose?

A decrease in blood pH:

Kidney tubule base bicarbonate reabsorption and hydrogen ion excretion tend to lower the blood pH and raise the pH of the urine.

The respiratory system is an important buffer system.

Which of the following types of acids would be produced as a result of glucose catabolism?

Overall,the kidney is less effective in controlling blood hydrogen ion concentration than is the respiratory system.

Which of the following is not a base-forming element?
