Practice question

Cannot generate another action potential (B) is the right choice. This sits at the heart of Action potential: the wording points straight to what is happening in the tissue or organ system. A useful study habit is to ask what the structure or process is for: excitable-cell physiology turns on membranes, ions, and signalling steps, and Cannot generate another action potential captures the correct piece of that story. That reasoning supports Cannot generate another action potential. One solid sentence about why this works is enough for recall — you do not need a long essay for every MCQ. When you practise, cover the choices first, write Cannot generate another action potential from memory, then reveal the letter — that habit builds real recall for Action potential.
