Re: Resonance transfer

... fluorochrome that has an excitation energy matching the emission energy of the first fluorochrome; in this case, let's say the second fluorochrome excites with green light and emits with red. Finally, the remaining excitation energy is emitted by the second fluorochrome as red light. This energy ...

Why does chlorophyll always fluoresce in red?

... blue light. The relatively weak red light causes chlorophyll's electron to jump one "energy level." Since blue light has more energy, it excites the chlorophyll's electrons even more: They jump two levels. (Ultraviolet has even more energy.) However, it's very difficult for the electron ...

An interesting essay I need help with

... an antedote. In your explanation, discuss in detail the mechanism of excitation-contraction coupling. Tell your dream date how a nerve normally excites a muscle, and be sure to include how an electrical impulse is able to travel so quickly along a nerve to a muscle. Next, explain and draw the ...

Nerve impulses and travel

... the inner ear... they hit the inner ear bones(i forgot the names of the bones) and then hit the cochlea... the liquid in the cochlea vibrates and excites the nerve endings.. then a nerve impulse is generated and travels to the brain area related to sound(forgot the name of that region too)... ...

Re: ATP hydrolysis releases energy, but what kind of energy?

... is that the hydrolysis of ATP results in transfer of an exciton to another reaction. What that means is that the energy released by the hydrolysis excites an electron to a higher energy level (I can't tell you which electron, but the exciton energy can be transferred atom to atom if the energy ...
