Chapter 37.7, Problem 2CYL
Summary Introduction
To explain:
How antibiotic resistance arises.
Introduction:
Antibiotic is a chemical substance which inhibits the growth of microorganisms or kills them. Antibiotics are produced by different species of living microorganisms, and they do not show any effect on the virus.

9. 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.

glycerol
A. 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. Continue
generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration.

A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
