Q:

What is the final electron acceptor of photosynthesis?

A:

Quick Answer

NADP+, or nicotinamide adenine dinucleotide phosphate, is the final electron acceptor in photosynthesis. NADP+ allows carbon dioxide to assimilate within the Calvin cycle by means of its reducing power. This enables carbon dioxide to be converted into glucose.

Full Answer

Photosynthesis is the biological process that converts light energy into chemical energy. Plants, algae and cyanobacteria are organisms that use photosynthesis. Since photosynthesis releases oxygen as a byproduct, plants and other photosynthetic organisms are responsible for maintaining atmospheric oxygen levels. In addition to the energy it provides, photosynthesis also produces almost all of the organic compounds necessary for life. The efficiency of photosynthesis used by plants is approximately between 3 and 6 percent, with most of the remaining energy dissipated as heat.

  • Q:

    How does NADP become NADPH?

    A:

    NADP, or nicotinamide adenine dinucleotide phosphate, becomes NADPH when a positive ion of NADP is reduced. This end result is called reduced nicotinamide adenine dinucleotide phosphate. This compound is often a part of biosynthetic reactions, which is what this change facilitates.

    What is the function of NADPH?

    A:

    NADPH, or nicotinamide adenine dinucleotide phosphate, is essential for photosynthetic organism carbohydrates. This reduced coenzyme is a high energy molecule and a reduced form of NADP+ that plays a key role in driving the Calvin cycle.

  • Q:

    What is the role of oxygen in aerobic respiration?

    A:

    Oxygen is used as an electron acceptor within the electron transport chain of aerobic respiration to generate adenosine triphosphate, or ATP. This compound is an essential component in intracellular energy transfer. Aerobic cellular respiration is in direct contrast of anaerobic respiration, which does not require oxygen.

  • Q:

    What is the role of NADP in photosynthesis?

    A:

    The role of nicotinamide adenine, or NADP, is to act as an electron carrier during the light dependent stages of photosynthesis. During the interaction, the electrons change NADP from its oxidized state - NADP+ - to its reduced state - NADPH.
