Chapter 23, Problem 1TQ
Summary Introduction
To review:
The possibility of crossing the placental barrier by microbial pathogens.
Introduction:
The placenta is the structural and functional unit between the maternal body and the developing embryo. It is formed by the interdigitating between chorionic villi and uterine tissue that provides nutrients and oxygen to the developing embryo. Other than transporting nutrients, the placenta removes CO2 (Carbon dioxide) and waste from the embryo and also acts as an endocrine gland. The development of normal microbiota in a developing fetus is largely determined by the already developed biota in the mother.

- 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.
