Answer:
Intermediate Product Accumulation
Explanation:
If one of the crucial enzyme say B is mutated in the process of normal product formation, then the reaction will not proceed further from that point and accumulation of an intermediate product in the cell takes place. The mutation in the enzyme could be environmental or genetic but it will surely alter the enzyme functioning. In the end, the damage malfunctioning cell will be removed using the process of apoptosis.
When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.
Unfortunately you didn't support your question with any options so that I could choose the correct one. But I am pretty sure I've got what you need so in eukaryotes, the components of the electron transport chain are located in the <span>inner mitochondrial membrane.</span>
