A Proton-Motive Force is the Conversion of ________ Energy into ________

Question

A proton-motive force is the conversion of ________ energy into ________ energy.
A)potential; chemical
B)potential; thermal
C)chemical; kinetic
D)chemical; potential
E)solar; chemical

Accepted Answer

A proton-motive force is created by the transfer of protons across a membrane. This transfer creates a concentration gradient of protons, which creates a potential energy difference on either side of the membrane. This potential energy can be used to drive the synthesis of ATP, which is a form of chemical energy. Therefore, the conversion is from potential energy (proton gradient) to chemical energy (ATP).
