Summary Introduction
To review:
Death of a bacterial cell when an antibiotic drug is formed.
Introduction:
Supercoiling is a unique or special property of double-stranded or circular DNA (deoxyribonucleic acid). The supercoiling of DNA also changes the topology of DNA. It provides an explanation for the connection between spatial features of an object. Enzymes that are responsible for supercoiling are called topoisomerases.

- 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.
