Yes, and it is predominant in photosynthesis in plants.
NADH and ATP
The molecule adenosine triphosphate, or ATP, is the energy carrier of the cell.
NADH delivers electrons to the electron transport chain in the mitochondria during cellular respiration. This transfer of electrons helps to generate a proton gradient across the inner mitochondrial membrane, which drives the production of ATP through oxidative phosphorylation.
Noncyclic electron flow results in the generation of ATP and NADPH. In this process, electrons are passed through the photosystems in the thylakoid membrane and ultimately drive the creation of these essential energy molecules.
In most cases iron shift between ferrous and ferric states to carry and transport electrons in cellular respiration. The cytochrome b and c complexes also play a major role. In aerobic organisms, oxygen is the final electron acceptor in cellular respiration.
NADH is the electron carrier that stores energy used to make ATP. It is a naturally-occurring and vital compound found in all living cells of plants, animals, and humans.
ADP/ATP (adenine-tri- phosphate)
One example of an electron carrier molecule is NAD+ (nicotinamide adenine dinucleotide). NAD+ is involved in redox reactions, acting as a carrier of electrons during cellular respiration to help generate ATP. It accepts electrons from substrates and becomes reduced to NADH, which can then donate the electrons to the electron transport chain for ATP production.
NADPH and ATP are produced by the light reactions. The ATP is a high energy molecule produced by photophosphorylation while the NADPH is produced at the end of the electron transport chain.
No, CoA (Coenzyme A) is not an electron carrier. It primarily functions as a carrier of acyl groups in various metabolic pathways, facilitating the transfer of acyl groups during fatty acid metabolism. NADH and FADH2 are examples of electron carriers.
NADH and ATP
The electron carrier molecules of aerobic respiration are NADH and FADH2. These molecules transport electrons from the citric acid cycle and glycolysis to the electron transport chain in the mitochondria, where ATP is produced through oxidative phosphorylation.
The Kreb's Cycle is a repeating series of reactions that produces ATP, electron carriers, and carbon dioxide.
FADH2 is the high energy electron carrier that produces fewer ATPs than NADH as its electrons pass through the electron transport chain. This is because FADH2 enters the electron transport chain at a later stage, leading to fewer ATP molecules being generated during oxidative phosphorylation.
An electron carrier acts as an energy-storage molecule when it is in a reduced state by gaining electrons and storing energy in chemical bonds. Examples of electron carriers involved in energy storage include NADH and FADH2, which are critical molecules in cellular respiration for ATP production.
it provides energy that powers the formation of ATP.
The two electron carrier molecules that feed electrons into the electron transport chain are NADH and FADH2. These molecules are produced during glycolysis and the citric acid cycle, respectively. The electrons carried by NADH and FADH2 are then transferred to the electron transport chain to generate ATP through oxidative phosphorylation.
