The reason that cyanide poisoning starts with the same symptom as altitude sickness. Introduction: The people who live at higher altitudes face some medical problems. They suffer from weakness, dizziness and so on. They even suffer from breath shortness. However, people suffering from cyanide poising also show the same symptoms. It has been discovered that the cyanide has the ability to bind to a molecule called cytochrome c oxidase. The binding of these two units reduces the concentration of oxygen present in mitochondria of the cell. As a result, this type of bonding of cytochrome c oxidase and cyanide inhibits the transfer of electrons inside mitochondria.

Aerobic respiration in eukaryotes produces less ATP per glucose molecule than aerobic respiration in prokaryotes. This is because: the electrons from cytoplasmic NADH in eukaryotes are shuttled to ubiquinone instead of NADH dehydrogenase. prokaryotes can produce a larger proton gradient across the inner mitochondrial membrane, thus causing a greater driving force for ATP synthesis. fermentation and the tricarboxylic acid cycle can run simultaneously in prokaryotes, generating two additional ATP per glucose molecule. eukaryotes must actively transport glucose into the mitochondria where respiration А. B. C. D. occurs. prokaryotes can generate 2.5 ATP per FADH2 molecule, whereas eukaryotes can only generate 1.5 per FADH2 Е. E.
