What happens when HCl is mixed with water?
What happens when HCl is mixed with water? When HCl is dissolved in water, ions of H and Cl are formed. Hydrogen loses an electron (becoming an ion of +1 charge) and chlorine gains an electron (becoming an ion of -1 charge). Strong acids, like HCl, release many more hydrogen ions in water than do […]
Why sugar is soluble in water?
Why sugar is soluble in water? The bond between the oxygen and hydrogen atoms (O–H bond) in sugar (sucrose) gives the oxygen a slight negative charge and the hydrogen a slight positive charge. The polar water molecules attract the negative and positive areas on the polar sucrose molecules which makes sucrose dissolve in water. Why […]

What are the steps of neurotransmitter release?
What are the steps of neurotransmitter release? Neurotransmitter release from the presynaptic terminal consists of a series of intricate steps: 1) depolarization of the terminal membrane, 2) activation of voltage-gated Ca2+ channels, 3) Ca2+ entry, 4) a change in the conformation of docking proteins, 5) fusion of the vesicle to the plasma membrane, with subsequent […]
