Hi Adam,

Welcome and thank you for contributing to Rejuvepedia!

I am very happy to see your contribution and I will help to develop this article. Do you have any sources or references for your contributions. If you can write them in the references section that would
be excellent.

		+	== Energy conversion ==
		+
		+	A dominant role for the mitochondria is the production of ATP, as reflected by the large number of proteins in the inner membrane for this task. This is done by oxidizing the major products of glucose, pyruvate, and NADH, which are produced in the cytosol. This process of cellular respiration, also known as aerobic respiration, is dependent on the presence of oxygen. When oxygen is limited, the glycolytic products will be metabolized by anaerobic respiration, a process that is independent of the mitochondria. The production of ATP from glucose has an approximately 13-fold higher yield during aerobic respiration compared to anaerobic respiration.[20] Recently it has been shown that plant mitochondria can produce a limited amount of ATP without oxygen by using the alternate substrate nitrite.

		+	'''Citric Acid Cycle'''
		+
		+	The citric acid cycle (CAC) is the ''final common pathway'' for the oxidation of fuel molecules and takes place inside the matrix of the mitochondria. Most fuel molecules enter the cycle as acetyl coenzyme A. Under aerobic conditions, pyruvate from glycolysis is oxidatively decarboxylated to acetyl CoA. <br>
		+	The CAC is the metabolic hub of the cell, supplying both 90% of the energy of higher mammals and many precursors for the building blocks of polymers, such as nucleic acids, amino acids and porphyrin. Its chief component, oxaloacetate is also a precursor for glucose. <br>
		+	Essentially, acetyl CoA is yielded from any fuel upon entering the matrix, which is then inserted into an oxaloacetate molecule and successively oxidised to reduce flavin adenine dinucleotide and nicotinamide adenine dinucleotide. The irreversible reaction which commits pyruvate to CAC metabolism is catalysed by ''pyruvate dehydrogenase complex'' (PDC):<br>
		+
		+	Pyruvate + CoA + NAD<sup>+</sup> -> acetyl CoA + CO<sub>2</sub> + NADH + H<sup>+</sup>
		+
		+	Electrons are hereby transferred from pyruvate to NAD<sup>+</sup>, which then moves on to supply energy for the ''electron transport chain'' (ETC). PDC itself is a large, highly integrated complex of three enzymes. It is a member of a homologous family of complexes that include the CAC enzyme α-ketoglutarate dehydrogenase complex. These complexes are giant, with molecular masses ranging from 4 to 10 million daltons. PDA contains three prosthetic groups: thiamine pyrophosphate, lipoamide and flavin adenine dinucleotide. <br>

This reaction, which is an aldol condensation followed by a hydrolysis, is catalysed by ''citrate synthase''. Oxaloacetate first condenses with acetyl CoA to form citryl CoA.

	+	'''Fatty Acid Metabolism'''

	+	Fatty acids play four major physiological roles:<br>
	+	1. Stored as triacylglycerols, they are fuel molecules. Comparing 38 kJ per gram of energy to 17 kJ per gram in carbohydrates and proteins.<br>
	+	2. They are building blocks for phospholipids and glycolipids - amphipathic molecules that are essential components of a plasmalemma.<br>
	+	3. Some proteins are covalently modified with fatty acids, targeting them to membrane locations.<br>
	+	4. Fatty acid derivatives serve as hormones and intracellular messengers.
	+
	+	Fatty acids destined for metabolism do not exist free but linked via a thioester bond to Coenzyme A.
	+	Fatty acid synthesis and degradation are the mirrors of each other, yet distinct.
	+	In synthesis, acetyl CoA (coenzyme A bonded to a two-carbon chain) and malonyl CoA (four-carbon unit) condense to form butyryl CoA. The carbonyl group is reduced to a methylene group in three steps: a reduction, a dehydration and another reduction.
	+	In degradation, an acyl CoA (depending upon the fatty acid chain length) is oxidised to introduce a double bond, which is then hydrated to a hydroxyl group, oxidised again to a ketone and cleaved ''by'' another CoA molecule to yield acetyl CoA, the common currency of the citric acid cycle and an acyl CoA two carbon groups shorter. The general process is oxidation, hydration, oxidation, cleavage; the reverse of synthesis.
	+	However, each pathway contains distinct enzymes, and a diferent mechanistically, exemplifying that synthetic and degradative pathways are almost always distinct.
