Admin What is produced in Calvin Benson cycle?
A cyclical series of biochemical reactions that occur in the stroma of chloroplasts during photosynthesis. It includes the light-independent reactions such as carbon fixation, reduction reactions and ribulose 1,5-diphosphate (RuDP) whereby sugars and starch are ultimately produced.
Where does the Calvin Benson cycle occur What does it produce and how?
Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts). This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
What are the products of the light-dependent reactions?
Explanation: The light dependent reaction converts solar energy to chemical energy, using the photosystem to capture light energy, and ultimately produce ATP and NADPH.
Is carbon dioxide produced in the Calvin cycle?
The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight.
How is ATP produced in light reactions?
In a process called non-cyclic photophosphorylation (the “standard” form of the light-dependent reactions), electrons are removed from water and passed through PSII and PSI before ending up in NADPH. This process requires light to be absorbed twice, once in each photosystem, and it makes ATP .
Is water produced in the Calvin cycle?
Further, since the Calvin cycle involves 3 reactions of CO2 with RuBP, you get a net production of 3 molecules of water.
What molecules are produced during the light 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.
