Question
Chapter 4.3, Problem 14BYGO
Summary Introduction
To determine:
Two diseases caused due to nondisjunction of autosomes, and two diseases caused due to nondisjunction of sex chromosomes.
Introduction:
Sometimes genetic defects caused due to aneuploidy, which is an abnormal chromosomal number in the zygote. Nondisjunction is the cause of aneuploidy. Nondisjunction is caused due to improper separation of chromosomes (autosomal or sex chromosomes) during meiosis. Due to this, both pairs of the chromosome go to the same cell.

- 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.
