dark reaction of photosynthesis is called so because

Often called carbon assimilation, photosynthesis is expressed by the following equation; 6CO 2 + 6H 2 O——— > C 6 H 12 O 6 + 6O 2 The light energy is transformed into chemical energy during the photosynthesis process and is stored into the organic matter, which is normally carbohydrates, and O2 is a by-product of photosynthesis. The dark reaction in photosynthesis is called so because of. | EduRev NEET Question is disucussed on EduRev Study Group by 156 NEET Students.

So, the dark reaction in photosynthesis is called so because it does not require light energy. Light is not required for dark reactions. photosynthesis in higher plants. 8. (g) True Solution C.5. Instead, dark reaction uses ATP and NADPH to produce energy molecules. If a plant is kept in bright light all the 24 hours for a few days, the dark reaction (biosynthetic phase) will continue to occur because the dark reaction is independent of light and it occurs simultaneously with the light dependent reaction. It takes up O2, and uses ATP to end up with CO2. Dark reaction in photosynthesis is called so because. The light reaction takes place only in the presence of sunlight and therefore it is also called the light-dependent reaction. Apart from being the largest NEET community, EduRev has the largest solved Log in. A series of reactions, called light-dependent reactions, start by the absorption of light by pigments (not just chlorophyll, as commonly misunderstood) in plant cells.This is followed by a series of light-independent reactions, so named not because they happen in the dark but because they do not directly involve light; … Explain how during light reaction of photosynthesis, ATP synthesis is a chemiosmotic phenomenon.
