The reason that the cyanide poisoning starts with the same symptoms as altitude sickness. Concept introduction: At a higher altitude, oxygen concentration decreases in the air. It creates shortness of breath due to the low oxygen concentration. Cyanide binds to cytochrome c oxidase that prevents the reduction of the oxygen molecule as it stops the transfer of electrons in the final steps of electron transfer chain.

Summary Introduction

To explain: The reason that the cyanide poisoning starts with the same symptoms as altitude sickness.

Concept introduction:

At a higher altitude, oxygen concentration decreases in the air. It creates shortness of breath due to the low oxygen concentration. Cyanide binds to cytochrome c oxidase that prevents the reduction of the oxygen molecule as it stops the transfer of electrons in the final steps of electron transfer chain.

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.

ak1: Why must the transfer of electrons from glucose to oxygen during aerobic respiration takes place in a series of steps? It is chemically impossible to transfer electrons directly from glucose to oxygen The energy of the electrons can be used to make ATP The energy of the protons can be used to make ATP The energy of the electrons can be used to make ADP
