Excitation

... effect of this neurotransmitter is terminated by different ways. 1. It may be degraded by the enzyme (as you mentioned), thus preventing continous excitation of the postsynaptic neuron. 2. Sometimes it diffuses out of the synaptic cleft. 3. It may be reabsorbed by the presynaptic neuron and packaged ...

... l-phenylalanine (around 500mgs) which is a pre-cursor to neurotransmitters like dopamine, noradrenaline, and adrenaline. I noticed a strong mental excitation effect. Yet, there is almost a gram per serving of l-phenylalanine in the whey and I don't notice these effects. I realize that my body uses ...

... events in the functioning of photosystem II is false? A. Light energy excites electrons in an antenna pigment in a photosynthetic unit B. The excitation is passes along to a molecule of p680 chlorophyll in the photosynthetic unit C. The p680 chlorophyll donates a pair of protons to NADPH, ...

... on how the cell is fixed (some fixation processes made cells permeable). The fluorochrome is detected by fluorescence microscopy, always involving excitation of fluoresence with a defined wavelength band of light and detection of the longer-wave emission from the fluorochrome. Generally for epifluorescence ...
