Neurons in the parasympathetic pathway use which neurotransmitters?
Kay [80]
<h2>Acetylcholine</h2>

Explanation:

  • Acetylcholine is a chemical that is found between the nerve synapses, or gaps, between nerve cells. When activated, it causes the contraction of skeletal muscles and activates glandular functions in the endocrine system. Think of acetylcholine as a mailperson; residents cannot receive their mail until he or she comes and delivers it to the mailbox. Like mailpersons who deliver the mail and move on to the next house, acetylcholine acts quickly and does not hang around. As a result, acetylcholine is rapidly broken down by another chemical substance called cholinesterase.
  • Acetylcholine was the first neurotransmitter scientists discovered, as well as the most abundant neurotransmitter in the body. A neurotransmitter is a chemical that is released by a neuron, or nerve cell, that sends a signal to another neuron across a synapse. The neurotransmitter binds to receptors to affect how the signal is received. The purpose of the neurotransmitter is to either amplify or inhibit the signals sent between the neurons.
  • Acetylcholine plays an important role in the signal of muscle movement, sensation of pain, learning and memory formation, the regulation of the endocrine system and rapid eye movement (REM) sleep cycles.

A scientist runs an SDS-PAGE experiment two separate times on a protein with a molecular weight of 200 kD. For the first experim
Delicious77 [7]

Answer:

This protein consists of 8 subunits of equal size linked by disulfide bonds

Explanation:

The sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) is a technique widely used in molecular biology laboratories to separate proteins with molecular weights between 5 and 250 kDa. SDS is an anionic detergent used to denature proteins before electrophoresis. SDS can denature proteins by altering non-covalent bonds such as hydrogen, hydrophobic and ionic interactions, but they cannot cleave disulfide bonds. In this case, reducing agents (e.g.,  β-mercaptoethanol or dithiothreitol) have been used to cleave disulfide bonds.

What is the difference between an excitatory postsynaptic potential and an inhibitory postsynaptic
Vikki [24]

Answer:

A postsynaptic potential is defined as excitatory if it makes it easier for the neuron to fire an action potential. ... A postsynaptic potential is considered inhibitory when the resulting change in membrane voltage makes it more difficult for the cell to fire an action potential, lowering the firing rate of the neuron.
