Calculate the Free-Energy Change Associated with Pumping Protons Out of a Cell

question 78

Short Answer

Calculate the free-energy change associated with pumping protons out of a cell if the pH inside is 7 while the pH outside is 6. Assume 37°C (310K) and a 50 mV membrane potential (inside negative). (R = 8.315 J mol^-1 K^-1; Faraday constant = 96,480 J V^-1.)

Definitions:

Normal Model

A distribution of probability that exhibits symmetry around the mean, demonstrating that data points close to the mean occur more frequently than those far from it.

Volumes

Quantities of three-dimensional space enclosed within a boundary or the contents within a container, measured in cubic units.

Normal Model

A symmetric probability distribution around the mean, indicating that occurrences of data are more common close to the mean than far from it.

Snowfall
