Web22 jul. 2024 · The double membrane found in mitochondria and chloroplasts appears to be a relic of the absorption of the prokaryotic bacteria by the eukaryotic host cells. The inner membrane which now contains numerous folds apparently came from the bacterial membrane while the outer membrane came from the host cell itself. WebDuring cellular respiration, electrons are transferred to the electron carrier molecules. NADH and FADH2. In eukaryotic cells, the Krebs cycle occurs in the. mitochondrion. In glycolysis and the Krebs cycle, electrons are removed from glucose and taken up by molecules like NAD+. In such a reaction, glucose is being _____ and NAD+ is being ____.
