Introduction:

Oxygenic photosynthesis is the process through which plants convert inorganic substances into food, using sunlight. It involves the absorption of sunlight by chlorophyll and using it to convert inorganic substances into food energy. The process of photosynthesis takes place in several steps and stages, involving various parts of the cell and thylakoid.

Expert Solution & Answer

Explanation of Solution

a) Photosynthesis: Photosynthesis is a light-driven biochemical reaction where CO₂ (carbon dioxide) and water (H₂O) are converted into organic molecules like glucose, with the help of chlorophyll and energy from sunlight, which is used by the plant as a food source.

b) Photosystem: Photosystems are biochemical mechanisms like membrane-bound protein complexes found in chloroplasts or the cell membrane of photosynthetic bacteria that perform photosynthesis. They are involved in the transfer of energy and electrons.

c) Reaction center: Reaction center is the functional component of a photosystem that uses the captured light energy (of a certain wavelength) to drive trans-membrane electron transport. It consists of proteins complexes and certain pigments (chlorophyll) that absorb light.

d) PSI: PSI (photosystem-I) is one of the two photosystems present in the membrane of thylakoid of chloroplast and is composed of protein complexes and forms an integral part of the membrane, it uses light-driven transport to synthesize ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate reduced).

e) PSII: PSII is the first component of a photosystem that is a large membrane-spanning protein–pigment complex, which oxidizes water molecules to release an electron and donates energized electrons (excited by sunlight) to electron carriers.

Conclusion

Hence, photosynthesis is a process comprising of different processes and systems like PSI and PSII and certain pigments like chlorophyll, forming the reaction center.
