AQA 2023 Question Paper & ANSWERS [VERIFIED] When a nerve impulse arrives at a synapse, it causes the release of neurotransmitter from vesicles in the presynaptic knob. Describe how - ANS nerve impulse causes calcium ion channels to open calcium ions enter by facilitated diffusion causes synaptic vesicles to fuse with presynaptic membrane Use your knowledge of how myosin and actin interact to suggest how the myosin molecule moves the mitochondrion towards the presynaptic membrane - ANS myo...
