Consider the Transport of Glucose into an Erythrocyte by Facilitated

question 76

Multiple Choice

Consider the transport of glucose into an erythrocyte by facilitated diffusion. What is the free-energy change for glucose uptake into the cell when the glucose concentrations are 5 mM on the outside and 0.1 mM on the inside? (These values may be of use to you: R = 8.315 J/mol · K; T = 298 K;(Faraday constant) = 96,480 J/V; N = 6.022 × 10²³/mol.)

• A) less than 2 kJ/mol
• B) about 10 kJ/mol
• C) about 30 kJ/mol
• D) about -30 kJoule/mol
• E) It is impossible to calculate without knowledge of the membrane potential.
