Enzyme carriers: NADP* and NADPH Flashcards
What is NADP+ short for?
Nicotinamide Adenine Dinucleotide Phosphate
Is NADP+ a high-energy or low-energy molecule?
Low-energy molecule
NADP+ is involved in what process?
Photosynthesis
Show the equation for the formation of NADPH from NADP+
NADP+ (low energy) + 2 electrons + H+ —-> HADPH (high energy)
Show the equation fro the breakdown of NADPH
NADPH (high energy) —> NADP+ + 2 electrons + H+
What does the hydrogen atom consist of? How are they symbolised?
A proton, symbolised as H+, and an electron
What can NADP+ accept to form NADPH? What is it combined with?
A pair of high energy electrons (combined with a hydrogen ion or proton) to form NADPH
Give the broken down formation of NADPH from NADP+
NADP+ + 1e- —> NADP
NADP + 1e- —> NADP-
NADP- + H+ —> NADPH
The addition of electrons to a molecule is called what?
Reduction
What is reduction?
The addition of electrons to a molecule
NADP+ is said to be what (in terms of NADPH)
NADP+ is said to be reduced to NADPH
What is NADPH?
It is an electron and hydrogen carrier
What is NADPH is used in photosynthesis to form glucose?
The energy and hydrogen it contains is used in photosynthesis to form glucose
Which forms glucose? NADPH or NADP+?
NADPH
What does NADPH release when it is broken down?
It releases two high-energy electrons and a hydrogen ion or proton when it breaks down
