responsible. Overproduction of lactate also occurs with cyanide poisoning or certain malignancies. Underutilization involves removal of lactic acid by oxidation or conversion to glucose. Liver disease‚ inhibition of gluconeogenesis‚ pyruvate dehydrogenase (thiamine) deficiency‚ and uncoupling of oxidative phosphorylation are the most common causes. The kidneys also contribute to lactate removal. Concerns have been raised regarding the role of metformin in the production of lactic acidosis‚ on the basis of

fructose. The individuals liver and kidneys attempt to use this sugar for energy and due to the incomplete breakdown of fructose‚ toxic byproducts are produced which eventually leads to serious illness. The genetic condition causes an enzyme deficiency (fructose-1-phosphate aldolase) which in turn causes the build-up of fructose-1-phosphate . The overabundance of fructose-1-phosphate prevents glycogen breakdown and ultimately the

are codes for certain function that are found in DNA. The combination of genes is what makes each individual unique. MCADD is a genetic disorder‚ caused by a mutation or damage to the gene‚ ACADM‚ that codes for the enzyme‚ medium chain acyl CoA dehydrogenase. This results in the enzyme being absent or existing in minimal quantities. An enzyme increases the rate of a chemical reaction. Our body needs many enzymes in order to make the materials needed for our bodies to function and be healthy. The mutation

Enzymes are biological molecules‚ or proteins‚ that act as catalysts. Enzymes help complex reactions so that they may occur everywhere in life. For example‚ when you eat meat‚ the proteases work to help break down the peptide bonds that occur among the amino acids. Enzymes usually work to complete one specific job which makes them specific catalysts. They also won’t be found all over the body‚ enzymes are found in neural cells‚ intestinal cells‚ and saliva. Enzymes are among the many organic macromolecules

red blood cell count is below normal. A normal hemoglobin count for a female is 12.0grams/100ml and 13.5grams/100ml for a male. This can be hereditary but it can also occur in the body for a number of reasons such as massive blood loss‚ vitamin deficiency‚ and cell deformities. Anemia Anemia is a common blood disorder that occurs when your level of healthy red blood cells is too low. Red blood cells contain a protein called hemoglobin‚ which is responsible for carrying oxygen to the tissues. Anemia

Enzymes and ATP Enzymes act as protein catalysts in biochemical processes Enzymes bind to a substrate and forms the enzyme substrate complex. Enzymes work by lowering the energy of activation. Activation energy must be supplied for the reaction to begin‚ once supplied‚ the reaction can proceed on its own. Enzymes can speed up events. They are not used by during the reaction because the enzyme stays the same‚ it does not change during the reaction. (Hudon-Miller‚ Enzymes‚ 2013) Enzymes act as

The consumption of alcoholic beverages dates back to approximately 10‚000 years ago when viticulture’ (the selective cultivation of grape vines for making wine) is said to have originated in the mountains between the Black and Caspian Seas. (1) It is one of the most commonly used psychoactive drugs in the world. Alcohol interacts with gamma amino bultyric acid (GABA) receptors in the
