It includes studies of the mechanisms of drug absorption‚ distribution‚ metabolism‚ and excretion; onset of action; duration of effect; biotransformation; and effects and routes of excretion of the metabolites of the drug 4. Examine the processes of absorption‚ distribution‚ metabolism‚ and excretion‚ and explain why they occur in this order. The reason why absorption‚ distribution‚ metabolism and excretion happen in that exact order is because absorption is the first step in

For the most part‚ life is cellular. Although there are several other requirements‚ that an organism needs to be considered alive. These requirements are macromolecules‚ it needs to have metabolism‚ and be able to reproduce. If something has all of these things then it can be considered alive. The first requirement is that it has to have cells. Beings also need macromolecules because they need energy. The four macromolecules are carbohydrates‚ lipids‚ proteins‚ and nucleic acid.

Tay-Sachs Disease Tay-Sachs disease is a rare inherited autosomal recessive disorder first discovered in 1881. It is a disease that is found in many populations‚ but commonly affects the populations of the Ashkenazi Jews. The disorder is caused when there is an absence of enzyme called beta hexosaminase A that is found on chromosome 15. The most common mutation occurs in mostly 80 percent of Tay-Sachs patients is the four base pair addition (TATC) on exon 11 and a G to C inversion

fatigue is a build up of the hydrogen ion‚ which increases the acidity in the muscle and slows down the enzymes. Chemical reactions add a phosphate group to replenish ATP‚ which in presence of oxygen is called aerobic metabolism( conversely without oxygen is anaerobic metabolism). Other substrates of energy sources stored inside the cell is called creatine phosphate. Is stored mostly in the muscles‚ therefore doesn’t require fat‚ sugar or oxygen; produces rapidly ATP and lasts for a very short

Human Endocrine System A system of glands and cells that make hormones that are released directly into the blood and travel to tissues and organs all over the body. The endocrine system controls growth‚ sexual development‚ sleep‚ hunger‚ and the way the body uses food. [pic] The human endocrine system modulates several processes of the body by the function of hormones. The endocrine system secretes hormones that control how bodily functions work. Thus‚ the human endocrine system watches

regulates energy. Food equals energy and the body stores that energy in fat cells and uses the energy as needed. The metabolism breaks down that food and uses the energy generated from that food for everyday activities such as walking‚ talking‚ thinking. The faster ones metabolism is the more efficient they are at breaking down food and using the energy. The slower the metabolism the more energy gets stored and gets turned into fat cells and not used. The hormone leptin‚ which is produced in fat

Chapter 9 1) Approximately how much water do you need each day to stay healthy? Water constitutes 50% to 70% of the human body. Its unique chemical properties enable it to dissolve substances as well as serve as medium for chemical reactions‚ temperature regulation and lubrication (found in the knees and other joints of the body); it also aids in regulating the acid base balance in the body. It helps remove waste from the body and is the basis for saliva‚ bile and amniotic fluid. It is
