Chapter 7, Problem 1CT
Summary Introduction
To determine:
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.

The higher the altitude, the lower the oxygen level in air. Climbers of very tall mountains risk altitude sickness, which is an illness characterized by shortness of breath, weakness, dizziness, and confusion. The early symptoms of cyanide poisoning are the same as those for altitude sickness. Cyanide binds tightly to cytochrome c oxidase, the protein that reduces oxygen molecules in the final step of mitochondrial electron transfer chains. Cytochrome c oxidase with bound cyanide can no longer transfer electrons. Explain why cyanide poisoning starts with the same symptoms as altitude sickness.

As a part of the ETC chain, it changes conformation to allow H+ ions to flow out of the matrix. It is found on the surface of the inner mitochondrial membrane and, therefore, contains start-transfer and/or stop-transfer sequences. With assistance from Bax, it can move out of the mitochondria and into the cytosol. It is considered a symporter because it is involved in electron transport. It is able to puncture holes in the plasma membrane to initiate apoptosis.arrow_forward

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.

Complex II allows the transfer of electrons from succinate to Coenzyme Q. Coenzyme Q is an electron which transfers electrons to Complex III. Electrons transfer from Complex III is associated with translocation.

Because the inner mitochondrial membrane is impermeable to L, when there is an excess of mitochondrial L, it converts to M using a TCA condensation reaction, M crosses to the cytosol using a designated transport system. In the cytosol, M reconverts to L and oxaloacetate. Oxaloacetate is subsequently converted to malate with simultaneous production of N, a prerequisite cofactor for the glycolysis pathway. This reaction is then followed by conversion of N to pyruvate which produces O, a prerequisite cofactor for the fatty acid synthesis pathway. L M N O A. ATP pyruvate malate NADPH B.
