Bacteria That Can Absorb Light Energy and Convert It into ATP

Question

Bacteria that can absorb light energy and convert it into ATP are commonly called
A)cytochromes.
B)lysosomes.
C)chemotrophs.
D)phototrophs.
E)cytochromes AND chemotrophs.

Accepted Answer

Bacteria that can absorb light energy and convert it into ATP are known as phototrophs. Choice A (cytochromes) and E (cytochromes and chemotrophs) are not correct because cytochromes are proteins involved in electron transport, not in the conversion of light energy into ATP. Choice B (lysosomes) is not correct because lysosomes are cellular organelles involved in the degradation of macromolecules. Choice C (chemotrophs) is not correct because chemotrophs obtain energy from chemical compounds, not from light.
