question 74

Short Answer

A proton that is moving freely has a wavelength of 0.600 pm. (m_proton = 1.67 × 10^-27 kg, e = 1.60 × 10^-19 C, h = 6.626 × 10^-34 J ∙ s)
(a) What is its momentum?
(b) What is its speed?
(c) What potential difference would it have been accelerated through, starting from rest, to reach this speed?

Reuptake

The process by which neurotransmitters are taken from the synaptic cleft back into the axon terminal for later use, thus terminating their excitatory or inhibitory effect on the receiving neuron.

Inhibitory Neurotransmitter

A type of chemical messenger that reduces or inhibits the likelihood of the neuron it acts upon to fire an action potential.

GABA

Gamma-Aminobutyric acid (GABA) is a neurotransmitter in the central nervous system that inhibits nerve transmission in the brain, calms neuronal activity, and is involved in reducing anxiety.

Serotonin

A neurotransmitter involved in various functions such as mood regulation, digestion, and sleep that can affect an individual's emotional state and general well-being.
