Active transport

... Active transport is the mediated transport of biochemicals , and other atomic / molecular substances, across membranes . Unlike passive transport , this process requires ...

Dendrite

... that action potentials do propagate back into the dendrites once initiated in the axon in most neurons. This backpropagating action potential is mediated by the activation of voltage-gated ion channels and can interact with synaptic input to alter the synaptic activity. The structure and branching of ...

Facilitated diffusion

... ) is a process of passive transport ( diffusion ) via which molecules diffuse across membranes , with the help of transport proteins ( mediated transport ). Small uncharged molecules can easily diffuse across cell membranes. However, due to the hydrophobic nature of the lipids that make ...

Neuron
