Summary Introduction
To write:
The stages of HIV infection with their symptoms.
Introduction:
HIV refers to a virus, which assaults the immune system cells, that is, the body’s natural defense against the illness. The virus leads to the destruction of a kind of white blood cell known helper T cells and creates duplicates of itself within the cells. Due to the destruction of T-helper cells, the immune system of an individual slowly gets weaken.

- Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2.
