ENZYMOLOGY DISORDERS OF METABOLISM By Wieslaw Faliszewski Our cells are using various types of substances in order to perform their functions. They also use them as a source of energy to perform all the required tasks. Some of those compounds come from the outside in the form of consumed food; others are synthesized in our body. Majority of those compounds have to be broken into simpler parts that can be used in different metabolic processes. The problem is‚ however‚ that most of the

Module 2 Study Guide 1. Definitions a. Metabolism- The process by whichc a living organism takes energy from its surroundings and uses it to sustain itself‚ develop and grow. b. Photosynthesis-the process by which an organism uses the energy from the sun to produce its own food c. Autotrophs- organisms that are able to produce their own food d. Heterotrophs- organisms that cannot make their own food and must obtain it from other organisms e. respiration -- the process by which food is converted

Lipids include fats‚ and the main function of fat is energy storage in animals. Fats are even richer in energy than

Lactic acid is produced when oxygen levels in the body drop. Causes Causes The most common cause is intense exercise. However‚ it can also be caused by certain diseases‚ such as sepsis‚ respiratory failure‚ cardiac failure‚ AIDS‚ cancer‚ and kidney failure. Metformin‚ a common

ups Identifying food groups in unknown solutions Aim The aim of this experiment is to identify different food groups within several different unknown solutions. This will be carried out by placing the unknown solutions into separate test tubes and using different chemical indicators to see if any reactions occur. Each food group will act different when the chemical indicator is added‚ some will change colour while others will separate. Introduction Food is a vital source of energy that is

Abstract This experiment focuses on the effects water bath temperatures have on D. melanogaster entering and recovering an anoxic coma. It was found that there was an indirect relationship between the amount of time it took D. melanogaster to enter and recover from an anoxic coma and the temperature of the water bath. D. melanogaster was able to enter and recover from the anoxia coma quicker when they were drowned in a cold water bath condition when comparing these results to the warm water bath

Excretion and Elimination of Toxicants and their Metabolites The first topic that was covered by this chapter was the excretion of wastes by the Renal system. The first step that occurs in the kidney deals with the nephron‚ which is the functional unit of the kidney. In the glomerulus the formation of urine begins with the passive filtration of plasma through the pores that are found in the glomerulus. The plasma is forced through these pores by hydrostatic pressure. The only things that determines
