Which of the Following Bioenergetic Processes CANNOT Occur in Hyperthermophiles

Question

Which of the following bioenergetic processes CANNOT occur in hyperthermophiles?
A) chemoorganotrophy
B) chemolithotrophy
C) photosynthesis
D) chemoorganotrophy and chemolithotrophy

Accepted Answer

Hyperthermophiles are organisms that live in extremely high temperatures. Therefore, photosynthesis is not possible as it involves the absorption of light energy by pigments which will be destroyed at such high temperatures. However, chemoorganotrophy and chemolithotrophy can occur in hyperthermophiles where they obtain energy from organic or inorganic compounds, respectively, and use that energy to produce ATP.
