Acetylcholine binds to sarcolemma; sarcolemma then T-tubules depolarize; Ca++ released from terminal cisternae travels along SR, is release into sarcoplasm, then binds to troponin to unblock tropomyosin binding sites allowing cross-bridge formation (i.e., myosin heads bind to actin).

What happens when a gas reaches a cold surface and it changes into a liquid?
Both a chemical and physical change occurs.
What is exchanged when water changes from one phase to another?
I see you're working on number 6. But the answer is Latent Heat.
Explain why the temperature of Wax remains constant during solidification?
it's because it releases the latent heat of fusion. Latent heat means energy is given out when a substance changes from liquid to solid without a change in temperature. and the transfer of energy doesnt change the KE of the particles, so the temperature remains unchanged. lanten heat gives rise to the change in PE of the particles during the change of state only
What is the relationship between energy and phase changes?
Adding or removing energy in the form of heat causes the phase change. The amount of heat to be added or removed is called latent heat. It changes the state of a substance without changing it's temperature. There are two types of latent heat. The latent heat of fusion, and the latent heat of vaporization. The latent heat of fusion must be added to change phase from solid to liquid, and removed to change from liquid to solid. The first change is endothermic and the second change is exothermic. The latent heat of vaporization must be added to change phase from liquid to vapor, and removed to change from vapor to liquid. Again the first change is endothermic and the second change is exothermic.
What is the difference between latent heat of fusion and latent heat of vapourization?
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization
Is a typhoon a chemical change?
No, a typhoon is a physical structure energized by the latent heat of phase changes involving water.
What happens when a gas reaches a cold surface and it changes into a liquid?
Both a chemical and physical change occurs.
What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
The energy that gas changes to liquid?
The latent heat of condensation.
Does Jimmy Swaggart suffer from Tourette syndrome?
Probably not. A nervous twitch could be a latent fear of the imminent rapture occurring.
Which chemical treatment produces a white-appearing latent print?
cyanoacrylate esther
What are two changes of state for water that cause latent heat to be released?
liquid and gas
What chemical reactions occur in the muscle during latent period of muscle contraction?
During the latent period of muscle contraction Ca++ is being released from the sacroplasmic reticulum and filament movement is taking up slack. This takes approx. 2 milliseconds.
The temperature at which matter changes from a liquid to a solid is called?
The latent heat of fusion. ____ Freezing point
Why does the temperature stops rising during melting and boiling point?
Because the latent heat of fusion and latent heat of vaporization are very high
What are latent prints?
Latent prints are fingerprints that are made and left behind by the deposit of oils and/or perspiration and they are invisible to the naked eye. They can be identified by using various physical and chemical detection techniques.
What is released as sensible heat during the formation of clouds?
Latent heat.
