Chapter 25, Problem 19CP
Summary Introduction
To determine:
Reason of infants having grater thermoregulation problems than adults.
Introduction:
Thermoregulation is the mechanism of regulation of heat. It is controlled by the hypothalamus section of the brain and this why it is called the thermoregulatory centre of the body. It is used to maintain homeostasis which is the state of complete chemical, hormonal, mechanical, mental and thermal stability. This mechanism is underdeveloped in infants and fully developed in adults.

- 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.
