True statement about photosynthesis are option- B, C, G, H.
A photosystem is one of two metabolic processes that take place during photosynthesis in chloroplasts.
The two steps of photosynthesis are sequential:
1. Light-dependent reactions
2. Light-independent reactions, or Calvin Cycle.
Light-dependent processes demand light, as the name suggests. In the light-dependent reactions, chlorophyll absorbs solar energy and transforms it into chemical energy that is then stored in the form of the energy-trading molecules ATP and NADPH (nicotinamide adenine dinucleotide phosphate) (adenosine triphosphate). The thylakoid membranes in the granum (stack of thylakoids), which is a part of the chloroplast, are where the light-dependent processes take place.
In photosynthesis, photolysis is a component of the Hill reaction, photochemical phase, light phase, or light-dependent process.
The energetic electrons from the light-dependent reactions supply the energy to convert carbon dioxide molecules into carbohydrates in the light-independent reactions, also known as the Calvin cycle. Because of the cyclical nature of the process, the light-independent reactions are occasionally referred to as the Calvin cycle.
The products of the light-dependent reactions are necessary for the light-independent reactions to work even though they don't involve light as a reactant and can thus occur day or night. The creation of new carbohydrate molecules is fueled by the energy carrier molecules ATP and NADPH, which are light-independent molecules. The energy carrier molecules then go back to the light-dependent processes to get more energized electrons once the energy has been delivered. Additionally, light activates a number of the enzymes involved in the light-independent processes.
Thus option B,C,G,H are correct.
