How neurotransmitters are removed from the synapse?

Biology
1 answer:
Anettt [7]3 years ago
8 0

Solution:

Neurotransmitters are chemicals messengers that transmit signals across a synapse from one neuron’s axon to another neuron’s dendrite. Neurotransmitters are released from the presynaptic neuron in vesicles that travel across the synaptic cleft where they are received by receptors on the postsynaptic neuron. Neurotransmitters can have either excitatory or inhibitory effects on the postsynaptic neuron by increasing or decreasing the probability that the postsynaptic neuron will create an action potential. Neurotransmitters are removed from the synaptic cleft by diffusion out of the cleft, removal by an enzyme, or via re-uptake pumps that actively pump the neurotransmitter back into the presynaptic axon.

A researcher is interested in mechanisms of neurotransmitter removal from the synaptic cleft following release from the axon terminal. He designs a series of experiments in mice to increase the rate of release of neurotransmitter to test effects on compensatory changes to removal processes. He also cultures neurons from the mice to test aspects of neurotransmitter release and removal in vitro.

Thus this is the required answer.

Which statement is most accurate concerning how photosystem II compares to the electron transport chain (ETC) of mitochondria? I
nordsb [41]

The correct answer is: In both systems, ATP is produced by chemiosmosis.  

Both of the processes, photosynthesis and electron transport chain in mitochondria use chemiosmosis (movement of ions across a semipermeable membrane, down their electrochemical gradient) to produce energy or ATP (via ATP synthase). The movement of hydrogen ions across the thylakoid membrane in order to galvanize the production of ATP is equal to the movement of those ions across the inner mitochondria membrane. Electrons are accepted by NADPH in photosynthesis (but not FADH2 as in mitochondria).
