Cell Membrane = Controls what comes into and out of a cell; found in plant and animal cells
Answer: C. Ii & III are correct
II. reduced intracellular ATP.
III. apoptosis or necrosis.
Explanation:
Cytochrome c oxidase controls the last step of food oxidation. Cytochrome c oxidase is an enzyme responsible for electron transfer in the electron transport chain (ETC), it inhibit in slowing down or stopping the ETC.
Consequently, ATP production would be gradually reduced, as the ETC is responsible for the majority of ATP production. This shows option II is correct.
The question starts by stating that cyanide is highly toxic, so this match up with the fact that a large dose would also cause cell death (apoptosis or necrosis). Therefore, option III is also accurate.
Option I: Inhibiting the ETC is consequential as it reduces oxygen demand because electrons would not flow to oxygen, the final electron acceptor.
Answer: A
Van Helmont concluded that most of the mass the plant gained had come from water.
One class of biomedical evidence of evolution, homologous molecules, is biomedical’s that are very similar in structure and function in all organisms
<span>Humans have around 24,000 genes and large parts of our genome actually consist of DNA that doesn’t code for genes. Prior to the completion of the human genome project, it was expected that humans would have over 100,000 genes.</span>
