Electron Transport Chain The first step in the electron transport chain process is for the NADH2 produced during glycolysis‚ the intermediate step‚ and the citric acid cycle to be attracted to Complex I (FMN ·FeS)due to its high affinity for NADH2. This attraction pulls NADH2 to Complex I (NAD dehydrogenase) and the two electrons from H2 are pulled off by the FeS (ferrous sulfate) leaving two H+ ions and NAD+. These molecules repel each other and this results in the NAD+ being recycled

Aldehyde and Ketone 1. ALDEHYDE Definition: An aldehyde is an organic compound containing a formyl group. This functional group‚ with the structure R-CHO‚ consists of a carbonyl center (a carbon double bonded to oxygen) bonded to hydrogen and an R group‚ which is any generic alkyl or side chain. The group without R is called the aldehyde group or formyl group. Aldehydes differ from ketones in that the carbonyl is placed at the end of a carbon skeleton rather than between two carbon atoms

metabolic cycles called the "Krebs" or "citric acid" cycle‚ and the oxidative phosphorylation electron transport chain. Vitamin B1(thiamine) is a coenzyme used in removing CO2 from various organic compounds. B2(riboflavin) is a component of FAD (or FADH2)‚ one of the chemicals used to transport electrons from the Krebs cycle to the electron transport chain. Vitamin B3(niacin) is a component of NAD+ (or NADH) which is the major transporter of electrons from glycolysis and the Krebs cycle to the electron

one unsuitable form of energy‚ this is known as ATP. ATP releases energy when broken down and is essential to the flow of energy to living cells. It can be re synthesized through a possible three energy systems; ATP-PC system‚ the glycolytic Lactic Acid system and the aerobic system. My chosen sport is trampolining the main performance in trampolining only lasts for a minute and is a high intensity sport. But in training that can be from an hour or two. ATP PC System is the breakdown of adenosine
