How is ATP and NADPH used in the Calvin cycle?
ATP and NADPH are used to convert the six molecules of 3-PGA into six molecules of a chemical called glyceraldehyde 3-phosphate (G3P). This is a reduction reaction because it involves the gain of electrons by 3-PGA. Recall that a reduction is the gain of an electron by an atom or molecule.
Where are ATP and NADPH used?
ATP and NADPH are produced in the light reaction of photosynthesis. These are used in the biosynthetic pathway. There are also used in the Calvin cycle to reduce carbon dioxide. During that process, the carbon dioxide is reduced to sugar.
Where do the ATP and NADPH used in the Calvin cycle come from quizlet?
What are the inputs to the Calvin cycle? Where do they come from? The inputs to the Calvin cycle are CO₂, ATP, and NADPH. The CO₂ comes from the atmosphere around the plant, and the ATP and NADPH come from the light-dependent reaction.
Where does the ATP and NADPH used in the Calvin cycle come from and what is it used for?
Light-dependent reactions harness energy from the sun to produce ATP and NADPH. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place.
What are ATP and NADPH used for in photosynthesis?
The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.
Which stage of Calvin cycle utilizes ATP?
The C3 cycle is another name for the Calvin cycle. It is the chemical reaction cycle wherein carbon one by one from the carbon cycle is converted into sugars. It tends to happen in the plant cell's chloroplast. The reduction stage of the C3 cycle utilizes ATP and NADPH to convert 3-PGA into glyceraldehyde-3-phosphate.
Where is the most energy used in the Calvin cycle?
Where is the most energy used in the Calvin cycle? Creating the higher-energy bonds in G3P requires the most energy in the Calvin cycle.
Where does energy for the Calvin cycle come from?
The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions.
Where does the Calvin cycle take place quizlet?
Where does the Calvin Cycle occur? The Calvin Cycle occurs in the stroma, whereas the light reactions occur in the thylakoids.
Why are ATP and NADPH important what process uses them to produce sugar and other organic molecules?
In the stroma, the Calvin cycle reactions use the chemical energy of ATP and NADPH to combine carbon dioxide from the air with organic molecules to form new molecules, like the sugar G3P. ADP and NADP+ are recycled and may be used again in the light reactions.
What are the roles of ATP and NADPH in photosynthesis quizlet?
What are the roles of ATP and NADPH in photosynthesis? Both of these molecules carry energy; in the case of NADPH, it has reducing power that is used to fuel the process of making carbohydrate molecules in light-independent reactions.
What is the importance of ATP and nadph2?
ATP and NADPH2from the light reactions are used in the dark reactions of photosynthesis that take place in the stroma region of the chloroplast. NADP (the vital coenzyme required for photosynthesis) is derived from nicotinic acid, a B-vitamin also known as niacin.
How is ATP used in photosynthesis?
ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.
