The important events in the course of an HIV infection in the absence of treatment. Concept introduction: HIV (Human Immuno Virus) is a virus that can residue in the human cells without expressing its effect. It belongs to the retroviruses family and contains single-stranded RNA. HIV enzyme “reverse transcriptase” transcribes its viral genetic material, RNA into DNA so that it can actively incorporate itself into the genetic material (DNA) of the host. Acquired immunodeficiency syndrome is a condition in which antibodies for HIV are present in conjugation with certain opportunistic infections. The patients with AIDS will suffer from sudden decreases in the number of CD 4 cells that causes diseases in the nervous system, skin, digestive system and dementia during final stages.

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

Awnser these Discussion Questions Answer these discussion questions and submit them as part of your lab report. Part A: The Effect of Temperature on Enzyme Activity Graph the volume of oxygen produced against the temperature of the solution. How is the oxygen production in 30 seconds related to the rate of the reaction? At what temperature is the rate of reaction the highest? Lowest? Explain. Why might the enzyme activity decrease at very high temperatures? Why might a high fever be dangerous to humans? What is the optimal temperature for enzymes in the human body? Part B: The Effect of pH on Enzyme Activity Graph the volume of oxygen produced against the pH of the solution. At what pH is the rate of reaction the highest? Lowest? Explain.
