Question

The chemiosmotic model of ATP synthesis is based on each of the following lines of experimental evidence except

-Artificial proton gradients established by addition of acid can drive ATP synthesis in the absence of electron transport.
-Oxidative phosphorylation does not require a membrane-enclosed compartment.
-The proton gradient established by electron transport has enough energy to drive ATP synthesis.
-Electron transport causes protons to be pumped out of the mitochondrial matrix.
-Uncoupling agents abolish both the proton gradient and ATP synthesis.

Answer 1

The chemiosmotic model of ATP synthesis is supported by the experimental evidence that the proton gradient generated by electron transport has enough energy to drive ATP synthesis.

Step-by-step explanation:

The chemiosmotic model of ATP synthesis is based on the experimental evidence that the proton gradient generated by electron transport has enough energy to drive ATP synthesis. This is the main principle of the chemiosmotic hypothesis.

Electron transport causes protons to be pumped out of the mitochondrial matrix, creating an electrochemical gradient that powers ATP synthesis through the enzyme complex ATP synthase. The other lines of evidence listed are all consistent with and support the chemiosmotic model.
