Jan 27, 2022 · Light-independent reaction is a series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide. The energy released from ATP (produced during the light reactions) drives this metabolic pathway.
Using the energy carriers formed in the first steps of photosynthesis, the light-independent reactions, or the Calvin cycle, take in CO 2 from the environment. An enzyme, RuBisCO, catalyzes a reaction with CO 2 and another molecule, RuBP.
The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO 2 and create a product that can be converted into glucose. The ultimate goal of the light-independent reactions (or Calvin cycle) is to assemble a molecule of glucose.
As it turns out, the atoms of carbon in your body were once part of carbon dioxide (CO 2 ) molecules in the air. Carbon atoms end up in you, and in other life forms, thanks to the second stage of photosynthesis, known as the Calvin cycle (or the light-independent reactions).
- Yes, they can. For example, morning glories and Venus flytraps move. Some other plants also have reflexive movement, as in a response to being touc...
- Yes. Because the plant can no longer absorb more H2O through its root structure, the plant will use what water it has stored. The wilting occurs be...
- It gets added to the glucose molecule( C.6 H.12 O.6 )
- actually the O is in between of C-1 and P. when 2H are added by NADPH2 , the bond between C and P breaks. 1H is used to reduce C. other H togather...
- Not quite. It is true that you need to fix six CO2 molecules for each glucose molecule you produce, and you need 6 ribulose-1,5-bisphosphate to do...
- Sugar goes into plastids to be stored or being actively utilized for plant growth, flowering and seeds.
- No it does not. All the oxygen released comes from "splitting" of water by photosystem II during the light-dependent reactions. The "extra" oxygen...
- 3 CO2 + 6 NADPH + 6 H+ + 9 ATP + 5 H2O → glyceraldehyde-3-phosphate (G3P) + 6 NADP+ + 9 ADP + 8 Pi (Pi = inorganic phosphate) Taken from wikipedia...
- because three carbons bond with 3 RuBp to make 3 molecules. This splits into 6PG or 6 phosphoglycerate. 6 phosphoglycerate is changed into 6 biphso...
- One cycle takes in one CO2. Three cycles, after many smaller steps, creates six G3P (three-carbon); here, five goes back into the cycle, and only o...
Oct 4, 2019 · The Calvin cycle is also sometimes referred to as the “light independent” reactions of photosynthesis, since it is not powered directly by photons from the Sun. Instead, the Calvin cycle is powered by ATP and NADPH, which are created by harnessing the energy from photons in the light-dependent reactions.

The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers ( ATP and NADPH) are products of light-dependent reactions.
