Summary Introduction
To explain:
In a short essay how chromosome behaviour during sexual reproduction inanimals ensures perpetuation of parental traits in offspring and, at the same time,
Introduction:
Chromosomes are the densely packed DNA molecule, found within the nucleus of a cell. During sexual reproduction the chromosome undergoes genetic recombination. During cell cycles the chromosome undergoes different phases to divide itself into two.

- 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.
