Movement of Solutes

Question 1

Whats the difference in rate of transport of non-carrier passive transport, versus carrier facillitated passive transport?

Answer 1

Transport without a carrier has not rate limit. Transport with a carrier does

Question 2

What defines active transport?

Answer 2

The ability to move a substance against the concentraiton gradient

Question 3

What is the chemical potential of a solute under standard condititons

Answer 3

mu=mu*+RTlnC+zFE+VP
E=electrical potential
V=Partial molar volume

Question 4

What is the formula for difference in chemical potential across a membrane?

Answer 4

Dela mu=RTln(ci/co)+F(Ei-Eo)

Question 5

WHat is the nerst equation?

Answer 5

delta E=2.303RTlog(co/ci)/zF

Question 6

Whats the Goldsman-Katz equation?

Answer 6

delta psi=(RT/F)*ln(P[solutes out]/P[solutes in])

Question 7

What is the name of a carrier that cause the formation/decay of delta psi across a membrane?

Answer 7

electrogenic

Question 8

how many pascals in a mega pascal?

Answer 8

10^6 pascals (a million)
