Which outcome is the main function of the light-dependent reactions of photosynthesis?
The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules. The light-dependent reactions are depicted in (Figure).
What is produced in the light-dependent reactions?
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH.
What are the 3 products of the light dependent reactions?
The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the thylakoids of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions.
What are the end products of light phase?
Difference between Light and Dark Reaction
| Light Reaction | Dark Reaction |
|---|---|
| The end products are ATP and NADPH. | Glucose is the end product. ATP and NADPH help in the formation of glucose. |
| The water molecules split into hydrogen and oxygen. | Glucose is produced. Co2 is utilized in the dark reaction. |
How does light color affect oxygen production?
The color of light affects the rate of photosynthesis when the production of oxygen increases at 450 nm (blue), drops, then rises again at 660 nm (orange). This green represents the green light, which has a low flow of oxygen.
Is 3646 a standard?
Parts 1 and 2 of the standard, when completed, will supersede IS 3646 ( Part 1 ) : 1966, IS 3646 ( Part 2 ), and IS 3646 ( Part 3 ) : 1968. Subsequent parts of the standard are intended to cover additional requirements that should be fulfilled while designing the lighting for a specific area.
What is the light intensity on Earth?
Intensity of sunlight at surface of the earth: 1 kW/m2 (1 kilowatt per square meter) Intensity of sunlight at “top” of atmosphere: 1.37 kW/m2 Approximately 20% iof incoming energy is scattered in the atmosphere and 80% is trans- mitted to surface.
