Phosphorylation plays a critical role in the regulation of many cellular processes including: cell cycle, growth, apoptosis and signal transduction pathways. It is the most common mechanism of regulating protein function and transmitting signals throughout the cell.
Fluorescence and phosphorescence are related but distinct properties of minerals. Fluorescence occurs when a mineral absorbs energy and emits light almost instantly, typically within nanoseconds, while phosphorescence involves a delayed emission of light that can persist for seconds to hours after the excitation source is removed. Both phenomena result from the excitation of electrons, but the mechanisms and durations of light emission differ significantly. Thus, while they share similarities, they are not the same mineral property.
Phosphorescence occurs in places all over the world and it happens when small micro organisms " glow" in the water. These plankton like creatures come from the bottom of the ocean where it's dark so they only come out at night. I have seen phosphorescence in the puget sound before and it occurs around the middle of august in the summer but in the sound it only happens in summer. Most of the times I have noticed it's a clear night with no rain.
This phenomenon is called phosphorescence.
The ability of a mineral or substance to glow during and after exposure to ultraviolet light is called fluorescence. If it continues to glow after the ultraviolet light has been turned off the effect is called phosphorescence.
Phosphorescence is not radioactive. It is a type of luminescence where energy absorbed from a light source is re-emitted slowly over a period of time, after the light source is removed. This process is different from radioactivity, which involves the emission of particles or energy from the nucleus of an unstable atom.

Bioluminescence is the production of light by living organisms, while phosphorescence is the emission of light by a substance after it has absorbed energy.
Phosphorescence is similar to fluorescence in that both involve emission of light by materials after they have absorbed energy. The main difference is the time scale: fluorescence is immediate, while phosphorescence has a delay before light is emitted.

Phosphorescence and fluorescence are both types of light emission, but they differ in how long they last. Fluorescence is a quick emission of light that stops as soon as the light source is removed, while phosphorescence continues to emit light for a period of time after the light source is removed.
Fluorescence and phosphorescence are both processes where a substance absorbs and then emits light. The key difference is in the timing of the light emission. Fluorescence happens almost immediately after the substance absorbs light, while phosphorescence involves a delay in the emission of light, which can last from milliseconds to hours.
Phosphorescence can be useful in mining eucryptite because it can help identify the presence of this mineral in the ore. Eucryptite typically exhibits phosphorescence under ultraviolet light, making it easier to distinguish from other minerals. This property can aid miners in locating and extracting eucryptite from the surrounding material.

Phosphorescence and bioluminescence are both forms of light emission, but they differ in their mechanisms. Phosphorescence involves the absorption of light energy and its slow release over time, while bioluminescence is the result of a chemical reaction within living organisms that produces light.
Phosphorescence lifetime
Becquerel was interested in phosphorescence because he observed that certain materials emit light after being exposed to sunlight or other forms of energy. This phenomenon intrigued him and led him to experiment with different materials to better understand the underlying processes involved in phosphorescence. His work eventually laid the foundation for the discovery of radioactivity.
