The bacterium brucella abortus can utilize the tetrose erythritol as a carbon source. the concentration of erythritol within a b. abortus cell is 10 mm, while the external erythritol concentration is at levels as low as 0.20 mm. what is the energy requirement for the inward transport of erythritol at 37°c under these conditions? hint: you may use the equation below. hint: in this case, t = 37 °c = 310 k.
a) dginward = +2,409.7 cal/mol·°
b) dginward = –2,409.7 cal/mol·°
c) dginward= +1,046.5 cal/mol·°
d) dginward= –1,046.5 cal/mol·°
