Chlorophyll solution is excited with UV radiation

[Evil]

hi ppl, i have some questions here about photosynthesis,really appreciate if you can answer them for me.
1) If a chlorophyll solution is excited with UV radiation, how do we know what colour is the fluorescence?
2)In the water splitting step of photosynthesis, two Hydrogen ions and one oxygen atom are formed. Whats to prevent them from forming water again or to react with other substances in the stroma?
3)Whatz the difference between ATP and NADPH , both structually and function wise.

thanks for your input. really appreciate it.

1) The fluorescence of the chlorophyll solution will emit light of a particular wavelength, which corresponds to the color of the light emitted.
2) The Hydrogen ions and oxygen atom that are formed in the water splitting step of photosynthesis can be stabilized by binding to specific proteins in the stroma, preventing them from reacting with other substances.
3) ATP is a molecule composed of an adenosine nucleotide and three phosphate groups. It serves as the main energy currency for cells and is used to power metabolic processes. NADPH is a reduced form of nicotinamide adenine dinucleotide phosphate, which is involved in many metabolic processes, including the synthesis of lipids, proteins, and nucleic acids. Functionally, ATP provides energy for metabolic processes, while NADPH serves as an electron donor in redox reactions.

1) The color of fluorescence in a chlorophyll solution excited with UV radiation depends on the specific type of chlorophyll present. Each type of chlorophyll has a slightly different chemical structure, which results in different fluorescence wavelengths. By analyzing the emission spectrum of the fluorescence, we can determine the color and type of chlorophyll present.

2) In the water splitting step of photosynthesis, the formation of two Hydrogen ions and one oxygen atom is not a spontaneous reaction. It requires energy from the light reactions to occur. Additionally, enzymes and other molecules in the stroma help to facilitate the formation of these products and prevent them from reacting with other substances in the stroma.

3) ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) are both energy-carrying molecules in photosynthesis. However, they differ in their chemical structure and specific functions. ATP is a nucleotide composed of adenine, ribose, and three phosphate groups. It is used as a direct source of energy for cellular processes. NADPH is a coenzyme composed of a nucleotide, a nicotinamide ring, and a phosphate group. It is primarily involved in providing reducing power for the synthesis of organic molecules. In short, ATP is used for immediate energy needs, while NADPH is used for long-term energy storage and building molecules.
