Aerobic Respiration

There is net gain of 38 ATP molecules during aerobic respiration of one molecule of glucose. But in most eukaryotic cells, 2 molecules of ATP are required for transporting the NADH produced in glycolysis into the mitochondrion for further oxidation. Hence, net gain of ATP here is 36 molecules.

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:
