Summary Introduction
Meiosis is a type of cell division. It contains two successive cell division such as meiosis I and meiosis II. Each division results in two daughter cells, thereby, meiosis finally produces four daughter cells. Meiosis is involved in the production of gametes. During fertilization, two gametes are fused and produce a zygote, a single cell. Errors during the process of meiosis I or II can result in extra or missing chromosomes in cells. These errors occur infrequently and most of them may produce lethal effects. Nondisjunction in meiosis may lead to extra or missing chromosomal DNA.

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. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…arrow_forwardDon't copy the other answerarrow_forward
