Retinal in prokaryotes is part of
A) photosynthesis.
B) phototaxis.
C) light-driven ATP synthesis.
D) light-driven ATP synthesis and phototaxis.

Question

Quizplus · Accepted Answer

Retinal in prokaryotes is involved in both light-driven ATP synthesis and phototaxis. It acts as a light-sensitive proton pump in some bacteria, facilitating the conversion of light energy into a proton motive force, which can then be used for ATP synthesis. Additionally, retinal-based proteins are involved in phototaxis, helping organisms move towards or away from light sources.
