Its NOT 'on the inside surface of the cell membrane'
Probably ' on the inside surface of the vesicle'

How would caffeine binding to an adenosine receptor affect the activity inside the neuron?
Adenosine receptors stick through the neuron membrane, so that part of them are on the inside and part is on the outside of the cell. Now, when adenosine, a natural chemical in the body, attaches to the adenosine receptor it shifts the shape of the receptor, this shift reaches all the way to the part on the inside of the cell, and causes the receptor to release attached molecules called G-proteins. These g-proteins now float around the inside of the cell and have all sorts of effects, in this case, to inhibit the neuron. Caffeine also binds to the adenosine receptor, but it doesn't activate the receptor. This means that the receptor is totally shut down, and can't work to inhibit the neuron any more. The end effect is to allow the neuron to be more active than it was before the caffeine.
What change does ACh cause in an ACh receptor?
ACh binds to each ACH receptor which causes opening of ligand-regulated ion gate and the creation of end-plate potential.
Compared to the ingested food molecules the end product molecules of digestion are usually?
smaller
Why are neurotransmitters sometimes referred to as a key?
When an action potential reaches the knoblike terminals at an axon's end, it triggers the release of chemical messengers called neurotransmitters. Within 1/10,000th of a second, the neurotransmitter molecules cross the synaptic gap and bind to receptor sites on the receiving neuron-as precisely as a key fits a lock.
The end product of glycolysis in anaerobic respiration?
The end product of glycolysis in the aerobic mode of respiration is 2 molecules of pyruvate and 2 molecules of ATP
Structure at the end of a neuron that detects information?
receptor
What is the receptor of a reflex arc?
Sensory receptor located at the distal end of a neuron or an associated sensory structure. When stimulated it creates a receptor potential, when that reaches its threshold, it will trigger 1 or more nerve impulses in the sensory neuron.
Which neurotransmitter receptor is present on the sarcolemma?
End of the muscle fiber I think it is the motor end plate

What gives rise to the cohesiveness of water molecules?
Water Molecules are polar molecules. That means that one end of the molecule has a slight positive end and one end has a slight negative end. Then just like a magnet, the positive end poles the negative end connecting the two.
What are the end products of respriation?
6 carbon dioxide molecules and 36 ATP molecules

Is a polypeptide a lipid?
No, polypeptides are not lipids. Polypeptides are large molecules also called proteins; lipids tend to be relatively small molecules with an "ionic" end and a "greasy" end.
Which molecules are most affected by microwaves?
Molecules that are most affected by microwaves are polar molecules. One end has a positive charge and the other a negative charge.
