p.770 right column 4th paragraph:"Mitchondria are formed at the soma. ATP synthesized here would take over 2 min to diffuse to the end of a 200-µm-long dendrite, and ~10 years to diffuse to the end of a 1-m-long axon, preventing rapid adaptation of the ATP supply in response to changing pre- and postsynaptic activity. Instead, therefore, mitochondria are transported long distances around neurons by kinesin and dynein motors, moving on microtubule tracks at ~0.3–1 µm/s. This has been reviewed extensively by [primary sources], who provide more detail
on the following points." |
