6 FAQs about [Does nadph store energy ]
Why is NADPH more important than NADP?
As in other reactions, NADPH helps carry electrons and protons driven by sunlight into new carbon-carbon bonds, creating sugar molecules. NADPH is often kept at higher concentration in the cytosol than NADP +, to allow for the easy reduction of small molecules into larger macromolecules.

NADPH is primarily produced in the oxidative part of the pentose phosphate pathway. NADPH is used in a) anabolic syntheses to produce cholesterol, fatty acids, transmittor substances and nucleotides. b) detoxifying processes as an antioxidant.
Why do chloroplasts use NADPH?
Chloroplasts in plants also use NADPH as part of the pathway to synthesize sugars from sunlight and carbon dioxide. As in other reactions, NADPH helps carry electrons and protons driven by sunlight into new carbon-carbon bonds, creating sugar molecules.
Is NADPH a universal electron carrier?
NADPH works with a wide variety of enzymes, and is considered one of the universal electron carriers. NADH – An analog of NADPH lacking a phosphate group, which functions in catabolic reactions. Electron Carrier – Molecules uses as intermediates in the transfer of electrons in biological pathways.
Why is NADPH a higher concentration than NADH?
NADPH is often kept at higher concentration in the cytosol than NADP +, to allow for the easy reduction of small molecules into larger macromolecules. The NADPH is more likely to lose its hydrogen and electrons when it is in high abundance. This can be contrasted to NADH, which is often found in lower concentration than NAD +.
What is the difference between NADPH and NADH?
The role of NADPH is mostly anabolic reactions, where NADPH is needed as a reducing agent, the role of NADH is mostly in catabolic reactions, where NAD + is needed as a oxidizing agent.
