If oxygen is available, pyruvic acid is used in aerobic respiration. However, if oxygen is not available, pyruvic acid is converted to lactic acid , which may contribute to muscle fatigue. This conversion allows the recycling of the enzyme NAD + from NADH, which is needed for glycolysis to continue. This occurs during strenuous exercise when high amounts of energy are needed but oxygen cannot be sufficiently delivered to muscle. Glycolysis itself cannot be sustained for very long (approximately 1 minute of muscle activity), but it is useful in facilitating short bursts of high-intensity output. This is because glycolysis does not utilize glucose very efficiently, producing a net gain of two ATPs per molecule of glucose, and the end product of lactic acid, which may contribute to muscle fatigue as it accumulates.

Anabolic processes tend toward "building up" organs and tissues . These processes produce growth and differentiation of cells and increase in body size, a process that involves synthesis of complex molecules . Examples of anabolic processes include the growth and mineralization of bone and increases in muscle mass. Endocrinologists have traditionally classified hormones as anabolic or catabolic, depending on which part of metabolism they stimulate. The classic anabolic hormones are the anabolic steroids , which stimulate protein synthesis, muscle growth, and insulin . [3] The balance between anabolism and catabolism is also regulated by circadian rhythms , with processes such as glucose metabolism fluctuating to match an animal's normal periods of activity throughout the day.

For children, these reactions should not be in balance.  In a child, the anabolic reactions have to be greater than the catabolic.  Boys start their growth spurt after girls.  That’s why when they are in 7th or 8th grade, the girls are still taller than the boys.  The boys change a couple years after the girls.  Guys may gain 2-3 inches in that growth spurt between 14-17 years of age.  During that growing period they will eat up all the food in your refrigerator.  They are growing like crazy during that time.  But what happens to both boys and girls at 18-19 is that if they keep eating the same way, they won’t grow taller anymore but only wider.  This is the phenomena everybody notices.

P-ATPases (sometime known as E1-E2 ATPases) are found in bacteria and also in eukaryotic plasma membranes and organelles. Its name is due to short time attachment of inorganic phosphate at the aspartate residues at the time of activation. Function of P-ATPase is to transport a variety of different compounds, like ions and phospholipids, across a membrane using ATP hydrolysis for energy. There are many different classes of P-ATPases, which transports a specific type of ion. P-ATPases may be composed of one or two polypeptides, and can usually take two main conformations, E1 and E2.

Hartnup disorder is an autosomal recessive impairment of neutral amino acid transport affecting the kidney tubules and small intestine. The disorder results from defects in the specific transport system responsible for neutral amino acid transport across the brush-border membrane of renal and intestinal epithelium. Deficiencies in the solute carrier family 6 (neurotransmitter transporter), member 19 gene (symbol SLC6A19) are associated with Hartnup disorder. The encoded protein is also referred to as the system B(0) neutral amino acid transporter 1 [B(0)AT1] protein. The characteristic diagnostic feature of Hartnup disorder is a dramatic neutral hyperaminoaciduria. Additionally, individuals excrete indolic compounds that originate from the bacterial degradation of unabsorbed tryptophan. The reduced intestinal absorption and increased renal loss of tryptophan lead to a reduced availability of tryptophan for nicotinamide adenine dinucleotide (NAD + and NADP + ) biosynthesis. As a consequence affected individuals frequently exhibit pellegra-like rashes
