At the inner mitochondrial membrane<span>, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the </span>membrane<span>, through ATP synthase.</span>
Answer:
option B
Explanation:
On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.

Neurosecretory cells make and release the hormones from the posterior pituitary. The cell bodies of these neurosecretory cells receive synapses from Afferent neuron and their axon terminals release hormones into blood stream or the local extracellular space.
Neurohormone is generally produced by neurosecretory cells and liberated by nerve impulses. Neurosecretory cells receive synapses from afferent neurons to guide magnocellular neurons .
A synapse is known as a small junction at the end of a neuron that allows any signal to pass through one neuron to another. Synapse is a junction were the one neuron get connected with the other neuron .

When a client comes into the emergency room (er) after hitting his head while playing any sport, if he is alert and oriented. immobilize the client´s head and neck would be a priority nursing intervention, because a head injury is treated as if a cervical spine injury is present until x-rays confirm their absence, then call for an immediate head computed tomography to look for any spine or head injury.
The serotonin binds to a G-protein -coupled receptor and activates a G-subunit . This results in activation of PKA and closing of the potassium channels. This will subsequently decrease the influx of potassium ions into the cell, and lead to depolarization of the cell. This changes the membrane potential of the cell.
Aplysia are sea slugs which fall under the category of mollusks. Serotonin is a hormone which is responsible for the transfer of electrical signals from the brain to different parts. In this particular mollusk, serotonin was studied to find that it is an essential neurotransmitter that is responsible for the maintenance of synaptic plasticity in the neurons. Synaptic plasticity is the feature which is essential for the communication of neurons. This is the modification which occurs at the synapses during the transmission of synapses. Without this activity, the transmission of signals would be impossible.
