- If the Tm for a particular amino acid is 220 mg/100 ml and the concentration of that amino acid in the blood is 130 mg/100 ml, the amino acid will Question options: a) not appear in the urine because it is too large to be filtered b) be actively secreted into the filtrate d) be completely reabsorbed by the tubule cells 回Focus English (United States)arrow_forwardHarry ate a late meal at a cheap diner on the way home from work.A couple of hours later, he vomited three times, and then he consumed several packages of an antacid (mostly NaHCO3) over thenext several hours. By the evening of the next day, he was feelingbetter. During this ordeal, his blood pH did not deviate significantly.Select the mechanism(s) that helped maintain Harry’s pH within anormal range.(1) increased respiratory rate(2) increased H+ secretion by the renal tubule(3) decreased respiratory rate(4) decreased H+ secretion by the renal tubulea. 1 b. 2 c. 1,2 d. 3 e. 3,4arrow_forwardExplain thoroughly the Buffering Action of following Biological or Physiological Buffers:(a) Phosphate Buffer System.(b) Bicarbonate Buffer system.arrow_forward

A 68-year-old man with chronic respiratory acidosis has an arterial pH of 7.34 and an arterial PCO₂ of 55 mm Hg. Which of the following best explains the compensatory response to the acidosis? A) Decreased HCI secretion by the stomach B) Decreased tubular secretion of HCO3 by the kidneys C) Increased CO₂ excretion by the lungs D) Increased HCO3 reabsorption by the kidneys E) Increased HCO3 transport by the choroid plexusarrow_forwardHypokalemia can cause life-threatening cardiac arrhythmias. What is the underlying cause of hypokalemia in DKA and HHNKS? Question 9 options: a) Osmotic diuresis b) Prior deficit from poor nutrition c) Shift of potassium back into cell due to fluid rehydration d) Shift of potassium out of the cell due to correction of metabolic acidosisarrow_forward
