Unlike eukaryotes, prokaryotes have no membrane-bound organelles. How, then, are prokaryotes able to generate energy?
Correct answer: D. Prokaryotes generate proton gradients across their plasma membranes
- A. Prokaryotes generate sodium gradients across their nuclear membranes
- B. Prokaryotes do not generate energy
- C. Prokaryotes produce energy via photosynthesis
- D. Prokaryotes generate proton gradients across their plasma membranes
Explanation
Although prokaryotes lack mitochondria and other membrane-bound organelles, they are able to generate a proton gradient across their cell membranes, and thus produce ATP by chemiosmosis.
