What do ATP and NADPH have in common?
What do ATP and NADPH have in common?
The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom. Recall that NADH was a similar molecule that carried energy in the mitochondrion from the citric acid cycle to the electron transport chain.
Where do NADPH and ATP come from?
ATP and NADPH are produced on the stroma side of the thylakoid membrane, where they can be used by the Calvin cycle.
Which has more energy ATP or NADPH?
The main difference between ATP and NADPH is that the hydrolysis of ATP releases energy whereas the oxidation of NADPH provides electrons. Furthermore, ATP serves as the main energy currency of the cell while NADPH serves as a coenzyme with the reducing power needed by the biochemical reactions.
What is the difference between NADPH and ATP?
The key difference between ATP and NADPH is that the ATP is the energy currency of many of the living organisms while the NADPH is the typical coenzyme used for the reduction reactions of anabolic processes seen in plants. On the other hand, NADPH works as an electron carrier in plants during the photosynthesis.
How does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
Which is the main product of ATP and NADPH?
Using ATP and NADPH, enzymes in the stroma of the chloroplasts can synthesize sugar/carbohydra ATP and NADPH are the main product of the Light reactions of photosynthesis.
How are NADPH and ATP used in the Calvin cycle?
ATP provides the free energy to power the Calvin Cycle (a.k.a. the Dark reactions). NADPH is the key electron donor (reducing agent). This provides the hydrogen and electrons needed to combine carbon dioxide into carbohydrate molecules. Using ATP and NADPH, enzymes in the stroma of the chloroplasts can synthesize sugar/carbohy…
How are electrons stripped from water to produce ATP?
The quick answer is that an electron is stripped from water and transferred to NADP+ to form NADPH which is an endergonic (requires energy imput) reaction.That energy is supplied by the sunlight absorbed in the chloroplasts. And in the process, a phosphorus is added to ADP to produce ATP.
What is the role of NADPH in photosynthesis?
NADPH is the key electron donor (reducing agent). This provides the hydrogen and electrons needed to combine carbon dioxide into carbohydrate molecules. Using ATP and NADPH, enzymes in the stroma of the chloroplasts can synthesize sugar/carbohydrate precursors out of CO2 and water.
