<span>Particularly the skeletal muscles at rest
gain most of their energy from the aerobic respiration of fatty acids. Hence
fatty acids provide the majority of the energy for muscle metabolism when a
person is exercising at 25% of VO2max. However, the motor neuron is at rest
when a neuron is not receiving any input there will be a potential difference.
Thus, the potential difference measured when the neuron is inactive and it is
caled the resting membrane potential. </span>
Bioaccumulation refers to the accumulation of a toxic chemical in the tissue of a particular organism.
Biomagnification refers to the increased concentration of a toxic chemical the higher an animal is on the food chain.
Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.
Explanation:
The charge in plasma membrane occurs with diffusion and electric fields.
For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).
The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.
For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.
The like charges repel, and opposite charges attract.
