Question 1

Where is the acid component in the Henderson-Hasselbach Equation?

Answer 1

In the denominator (0.031 x PCO2)

Question 2

From what reacton is the Henderson-Hasselbach equation derived from?

Answer 2

H2O + CO2 H2CO3 HCO3- + H+

Question 3

So, what enzyme is known for enhancing that reaction?

Answer 3

Carbonic anhydrase

Question 4

Answer 4

Carbonic dehydrotase

Question 5

So where is Carbonic anhydrase found?

Answer 5

Exclusively within RBCs and Renal Tubular Cells

Question 6

TRUE or FALSE, Carbonic anhydrase is found in serum.

Answer 6

FALSE.

Question 7

If excess amts of HCO3 are prod’d by RBCs and it leaks out of plasma, what is replaced inside? Why?

Answer 7

Cl-, for electroneutrality

Question 8

What do you call the process of exchange of Cl- and HCO3- in RBCs?

Answer 8
