Waar vindt de Ademhalingsketen plaats?
Deze keten van enzymen wordt de elektronentransportketen genoemd en bevindt zich in het binnenmembraan van het mitochondrion.
Hoe vaak citroenzuurcyclus?
Omdat tijdens de glycolyse per molecuul glucose twee moleculen pyrodruivenzuur vrijkomen, moet de citroenzuurcyclus twee maal worden doorlopen om een molecuul glucose af te breken. De naam citroenzuurcyclus is afgeleid van het eerste product dat ontstaat uit de serie omzettingen in deze cyclus; namelijk citroenzuur.
What is the function of NADPH in photosynthesis?
Function of NADPH. NADPH is the typical coenzyme used in reduction reactions, seen in the anabolic pathways of organisms. For example, when sugars are created during photosynthesis, carbon molecules are chained together using the energy from sunlight. NADPH function in transferring electrons and a hydrogen displaced by the energy of sunlight.
What is the difference between NADP + and nadnadph?
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.
Which can take place if NADPH is oxidized?
NADPH is created by the reduction of NAD +, and can only occur when another molecule is oxidized. NADPH cannot accept any more electrons, and therefore answer B cannot take place. Remember that NADPH is a coenzyme, and must be used in conjunction with an enzyme.
How does NADP+ react with electrons and hydrogen?
The NADPH first accepts the electrons and hydrogen when special enzymes transfer these particles to the molecule NADP+. In this reaction the NADP + becomes reduced when it accepts the electrons and hydrogen, going from a positive electrical state to a more negative neutral state as a NADPH molecule.
