Chapter 51, Problem 14PIAT
Summary Introduction
To review:
The data to be collected for a detailed life table tracking the cohort of the pythons.
Introduction:
A life table helps the researchers to predict the python population and other details. Details such as survivorship and fecundity must be obtained to construct a life table to track the cohort of pythons. The survivorship is the fraction of the population that survives, on an average, to a particular age. Fecundity refers to the ability to produce an abundant number of new offspring. The reason that both fecundity and survivorship cannot occur together is the fitness trade-offs.

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
