Question

Which of the following uses plasma membrane for respiration?

• A. Prokaryotes
• B. Eukaryotes
• C. Viruses
• D. Fungi

Hint:

In prokaryotes, the plasma membrane functions as the site for ATP production, similar to mitochondria in eukaryotes.

Answer 1

The Correct Option is A

Prokaryotes, such as bacteria, lack membrane-bound organelles like mitochondria. Instead, they use their plasma membrane for: \begin{itemize} \item Hosting enzymes for the electron transport chain. \item Carrying out ATP production via oxidative phosphorylation. \end{itemize} Eukaryotes perform respiration in mitochondria, while viruses lack metabolic processes. --- Final Answer: \[ \boxed{\text{Prokaryotes}} \]
