In biology, the cyclic electron flow is a process of biasing light reaction outputs so that photophosphorylation is increased over nicotinamide adenine dinucleotide phosphate production. This is a type of electron flow t... More »

When the chlorophyll molecule absorbs light, it is destabilized, and its relatively free-moving electrons are energized and donated to molecules which generate carbohydrates. This donation of energized electrons is the t... More »

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 ... More »

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 ... More »

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 carb... More »

The ion nicotinamide adenine dinucleotide, or NAD, is a crucial electron acceptor during the process of glycolysis. Glycolysis is the first step in breaking down glucose for use in cellular respiration, and it is the mai... More »

In chronological order, the four steps of cellular respiration are glycolysis, a transition reaction, the Krebs Cycle and an electron transport chain. Cellular respiration occurs in the cytoplasm and in the mitochondria. More »
