Question:- 1. Describe the role of differential electrical charge across the cell membrane in both non-excitable and excitable cells. Include in your description terms like equilibrium potential, hyperpolarization, depolarization, and the sodium-potassium pump. For excitable, think in terms of both neuron and muscle.

100% Normal text Arial 11 + ... I| I11 I 2 l 3 4 5 6 Select all the correct answers for the question that follows. The resting membrane potential of an excitable cell demonstrates a negative inner face because: the net flow of sodium ions is out of the cell through leakage channels sodium and potassium ion diffuse across the cell membrane according to their electrochemical gradients the net flow of potassium ions is out of the cell through leakage channels large negatively charged protein anions get trapped in the excitable cell O tv Aa ok Pro
Correct answer: Ligand-gated ion channel don’t open until the neurotransmitter diffuses across the synapse and binds to the receptor, The calcium channels are blocked in the presynaptic cells, It takes time for the vesicular exocytosis to occur Please explain why each of the correct answer choices are correct. Thank you.
