pH Regulation

Question 1

what do gastric and pancreatic cells do in BBS?

Answer 1

assists in the production of HCO3- secretion for digestion

Question 2

what do alveoli do in BBS?

Answer 2

enhance CO2 conversion for exhalation

Question 3

what do renal tubular cells do in BBS?

Answer 3

aids in H+ excretion and HCO3- reabsorption

Question 4

what do red blood cells do in BBS?

Answer 4

facilitates rapid CO2 transportation and buffering

Question 5

where is carbonic anhydrase found?

Answer 5

red blood cells
renal tubular cells
alveoli
gastric and pancreatic cells

Question 6

what does the carbonic anhydrase do?

Answer 6

catalyzes the reversible reaction between CO2 and H2O

Question 7

what is the primary enzyme of BBS?

Answer 7

Carbonic Anhydrase

Question 8

what are the key enzymes that facilitate BBS?

Answer 8

carbonic anhydrase
H+/ATPase
Na+/H+ exchanger
Anion exchange enzyme
bicarbonate transporter enzymes

Question 9

how does shifting equilibrium via renal regulate?

Answer 9

it regulates pH by adjusting the amount of HCO3- reabsorption and H+ excretion

Question 10

how does shifting equilibrium via respiration regulate?

Answer 10

it regulates the amount of CO2 exhaled

Question 11

T/F shifting equilibrium via renal is fast

Answer 11

False, it is a slow response

Question 12

what is Alkalosis in terms of respiration and renal?

Answer 12

H+ concentrations are depleted - pH is high

Question 13

what is acidosis in terms of respiration and renal?

Answer 13

H+ concentrations are elevated - pH is low

Question 14

T/F shifting equilibrium via respiration is slow

Answer 14

False, it is a fast response
