Question
Chapter 21.1, Problem 1TQ
Summary Introduction
To review:
The selection of optimal and suitable DNA (Deoxyribonucleic acid) extraction method for performing a metagenomic analysis of soil samples taken from various parts of wetlands.
Introduction:
Metagenomics involves the study of genetic material that is recovered directly from the environment. Analysis of metagenomic sequencing has posed severe challenges to most of the scientific researchers as this analysis has to follow a complex structure of steps. While doing so the researchers have to face environmental oriented hazards and also have to choose an appropriate target community.

- 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. 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_forward4.
