What is NADP and what role does it play in photosynthesis?
NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.
What is the role of NADP in photosynthesis quizlet?
What is the role of NADP+ in photosynthesis? It is reduced and then carries electrons to the Calvin cycle. As a component of photosystem II, it catalyzes the hydrolysis of water. It acts as the primary electron acceptor for the photosystems.
What is NADP used for?
A major role of NADP is its role as co-enzyme in cellular electron transfer reactions. Moreover, the cell spends a significant amount of energy to keep NADP in its reduced form, thereby maintaining a readily available pool of electrons to reduce oxidized compounds.
What is the full form of SAD?
Seasonal affective disorder (SAD): Seasonal affective disorder (SAD), a form of depression that tends to occur as the days grow shorter in the fall and winter.
How does NADP become reduced?
As it leaves the molecule, the electron is taken up by an electron acceptor and passed along the electron transport chain to produce ATP. The electron returns to PS1 and can be re-excited. The H+ and the excited electron from PS2 are taken up by NADP to form reduced NADP.
Why do we need two photosystems?
Due to the large difference in the redox potential between the electron donor (oxygen in a water molecule) and final electron acceptor during the light phase of photosynthesis (NADP+), the ancestor cyanobacteria had to evolve the capability to use two photosystems working in series in order to be able to accumulate the …
What is the most important function of PS II?
The most important function of photosystem II (PSII) is its action as a water-plastoquinone oxido-reductase. At the expense of light energy, water is split, and oxygen and plastoquinol are formed.
