Question
Chapter 25.5, Problem 16CYU
Summary Introduction
To review:
The intracellular enzyme and theblood concentration of the ion that increases when the urine in renal tubule cells and the parietal cells in the stomach are acidified.
Introduction:
The acidic medium in the stomach helps in the activation of digestive enzymes, which helps in the breakdown of food. Excess of acid level in the body is regulated by acidifying the urine and excreting it out of the body.

A person consumes 100 μg of a tracer chemical. Assume that the person is able to collect all of the tracer in their urine (and therefore measure the amount that has come out of the body), as well as the concentration in the blood, as a function of time (see table).
(a) Is a first-order rate constant appropriate for describingthe process of elimination via the kidneys? Justify your answer.(b) Assuming that the answer to a is “yes,” find the rate constant k and the total volume V from these data.
Suppose a patient has chronic metabolic acidosis, perhaps from type Il diabetes. Suppose a clinic is treating the acidosis by administering
bicarbonate in the blood. If the kidney's removal of bicarbonate were inconsistent, what is something simple the clinic could do to check if
the dosage of bicarbonate is appropriate?
Proteinuria (protein in the urine) after intense exercise may be physiological (normal). However, protein is typically not present in urine. Why is that?
