	Muscle metabolism: aerobic vs. anaerobic
		In photomicrographs of stained aerobic and anaerobic cells abutted against each other and with a capillary in the corridor between them, the mitochondria of the aerobic fibers are seen bunched near the capillary like moths around a flame, while the anaerobic fiber shows no such activity.
		The mitochondria are naturally at the periphery of the aerobic fiber but are spread in the interior of the anaerobic fiber.
		Aerobic fibers use large adenosine molecules as energy transporters, with AMP moving out to the mitochondria to be recharged to ATP, then lumbering back to the interior to activate calcium ion release.

		Metabolism is the term for a series of chemical reactions that provide energy in a form the organism can use for its own purposes: repairing cells, excreting wastes, making new cells, and reproducing.
		The central element of aerobic metabolism, and the reason it provides so much more energy, is a series of reactions in which an electron bounces down a chain of molecules until it reaches a final electron acceptor that is then excreted.
		In aerobic metabolism, hydrogen is the electron donor at the beginning of the process, and oxygen is the electron acceptor at the end.

	Aerobic vs. Anaerobic: What is The Difference? :: Provided by MyFoodDiary.com
		The problem with the terms "aerobic" and "anaerobic" when applied to exercise is that we actually never switch from total aerobic to total anaerobic metabolic conditions.
		Consequently, it is best to view the terms aerobic and anaerobic as transitions in metabolism, where the proportion between aerobic and anaerobic metabolism changes with changes in exercise intensity.
		Aerobic exercise tends to be less stressful to muscles, joints, and your heart, which may be important for individuals with arthritis, heart disease, or high blood pressure.

	Sect. 2, Ch. 4: Sources of ATP: Aerobic Metabolism (Site not responding. Last check: 2007-09-17)
		Aerobic (oxidative) metabolism takes pyruvate from the glycolytic pathway and, in the presence of oxygen, produces a net total of 36 ATP per glucose molecule.
		Not only is aerobic metabolism far more efficient in producing ATP, but its by-products are water and CO Water is, of course, innocuous.
		A disadvantage of aerobic metabolism is that it requires adequate blood circulation to deliver sufficient quantities of oxygen to the muscle cells, and to remove CO rapidly from those cells.

		In the human body, energy metabolism can be categorized into two basic types: (1) aerobic metabolism, which catabolizes energy substrates with the utilization of oxygen and, (2) anaerobic metabolism, which does not require oxygen for the catabolism of energy substrates.
		The contribution of anaerobic and aerobic metabolism is dependent on the duration and intensity of the activity.
		Aerobic Metabolism During Prolonged Exercise Depending on the intensity of exercise, once a steady-state VO2 is attained, it can usually be maintained for 10 to 30 minutes of continuous submaximal exercise.

		In fact, aerobic is a type of metabolism, the process by which your body breaks down or "burns" stored fuel to create energy.
		Aerobic exercise is the type that progressively places increased demands on the heart, causing it to grow stronger and more efficient.
		Aerobic activities - walking, running, swimming, cycling, etc. - should be intensive enough to raise and sustain your heartbeat to a target heart range or THR (60 - 68% of its maximum capacity) for at least 20 - 30 minutes.

	Aerobic Fitness, Its meaning and significance
		The term "aerobic" implies that the oxygen necessary to accomplish the work is taken up by the individual during the activity.
		In aerobic work, oxygen is obtained from the air and is transferred from the lungs to the blood and then to the muscles via the circulatory system.
		The main reason for this is that aerobic fitness is directly related to fat-free body weight, which consists mainly of the weight of muscles in the body, and on the average, males have a higher muscle mass than females.

	CYCLING PERFORMANCE TIPS - basic physiology - cell energy metabolism
		Aerobic metabolism, which requires oxygen (is oxygen dependent) refers to several different chemical processes in the cell, which produce ATP from all three food elements - carbohydrates, fats, and protein.
		Aerobic pathways are used by the muscle cells for energy production (metabolizing both fats and carbohydrates as an energy source) up to exercise levels of approximately 50% VO2 max.
		At that point (called the "crossover point"), although metabolism is still oxygen based (aerobic), it shifts towards glycogen as an energy source (and fat metabolism decreases).

	Glycolysis
		The first step in the metabolism of digestible carbohydrate is the conversion of the higher polymers to simpler, soluble forms that can be transported across the intestinal wall and delivered to the tissues.
		The metabolic result of the phosphorylation of the bifunctional enzyme is that allosteric stimulation of PFK-1 ceases, allosteric inhibition of F-1,6-BPase is eliminated, and net flow of fructose through these two enzymes is gluconeogenic, producing F6P and eventually glucose.
		Thus, the ability of an individual to metabolize ethanol is dependent upon the capacity of hepatocytes to carry out eother of these 2 shuttles, which in turn is affected by the rate of the TCA cycle in the mitochondria whose rate of function is being impacted by the NADH produced by the AcDH reaction.

	Conditioning for MMA
		And then establish how much of that endurance is derived from aerobic metabolism, and how much from anaerobic metabolism. For an intensive loading period of 3-5 minutes duration, roughly half of the energy is supplied by anaerobic metabolism and half from aerobic metabolism.
		Does this mean that one should forego aerobic training altogether? There is no clear consensus among the experts, though many do advocate the developing of an "aerobic base" particularly in the preparatory period of training, as appropriate aerobic training can improve circulatory processes and facilitate recovery.
		How then to develop endurance for the ring? For many years, research has shown that development of endurance is associated with the functional specialization of the skeletal muscles, particularly enhancement of their strength and ability to use oxygen, rather than improvement of cardio respiratory ability.

	What is the Metabolism and how can you increase, speed up or boost your metabolism? (Site not responding. Last check: 2007-09-17)
		The virtue of exercise is that it increases or boosts your metabolism by its effect on muscle cells throughout the body.
		The key to keeping your metabolism from decreasing from decade to decade is to keep exercising, and make sure you include resistance training to keep up your muscle mass.
		In the case of resistance training, the increased FFM burns maybe 50 more calories a day, and the raised metabolism from aerobic training nets an extra 25 to 30 (this, of course, is not counting the calories burned during the activities themselves).

	Letters from Terra - Biochemistry - Amino Acid metabolism
		The carbons skeletons of all of these disparate and diverse compounds are derived, universally throughout life on this planet, from glycolytic intermediates, metabolites of the Krebs cycle and the Pentose phosphate pathway, and in the case of histidine from nucleotide (purine) metabolism.
		All the ingenuity of the basic metabolic pathways of carbohydrates and fatty acids has been harnessed to yield a spectrum of protein components; common motifs are mixed and recombined, defined chemistry is applied to novel substartes, and echoes of each pathway reverberate throughout the whole system.
		The metabolism of the amino acids is in itself another basis for more complex or specialised reactions, utilising the scemata of these pathways in the same way that the reactions characterised below employ the other metabolic pathways.

		While it is true that certain infections, cancers and other adversities thrive in an anaerobic environment, it is not true that anaerobic is “bad” and that aerobic is “good” or that everyone should do whatever possible to increase oxygen and aerobic metabolism in the body.
		A prolonged, out-of-control aerobic metabolism is undesirable since the result is unregulated free radical production, tissue destruction and accelerated tissue aging.
		Since oxygen is classified through metabolic typing as a Catabolic, aerobic nutrient, oxygen therapies only add fuel to the fire in someone with a catabolic imbalance and can thus worsen rather than improve such conditions.
