Part Three: Acid/Base Homeostasis in the Human Body

Beginning Questions:

  1. Carbon dioxide is formed during cellular respiration and then diffuses out of cells into the interstitial fluid and then into the bloodstream.

chemical engineering
*An adult human being at rest produces roughly 0.40 mJ/h of thermal energy through metabolic activity. Use that fact to solve the following problems.
(a)
A college student who weighs 128 pounds put off a major assignment until the day before it was due and worked for eight hours to complete it. If she is modeled as a closed adiabatic system at constant pressure, her heat capacity and molecular weight are approximately the same as that of liquid water, and her temperature was normal when she began to work, what would her temperature have been by the time the assignment was finished?
(b)
Now model the student as an open system and assume that evaporation of perspiration (evaporative cooling) is the only mechanism for heat loss. How much weight would she have lost through evaporation if she maintained a constant body temperature?
(c)
Are either of the models in Parts a and b reasonable? Explain. What is the most likely explanation of what happened to the metabolic energy produced in her body?

1. Determining Inheritance using Punnett Squares

A Punnett is a means to determine the genetic inheritance of offspring if the genotypes of both parents are known. Using Punnett squares answer the questions about the following scenarios. In order to properly answer some of the questions more than 1 Punnett square might be needed. With every Punnett square provide a key for your alleles.

  1. Neurofibromatosis (NF), sometimes called von Recklinghausen disease, is one of the most common genetic disorders. It affects roughly 1 in 3,000 people. It is seen equally in every racial and ethnic group throughout the world. At birth or later, the affected individual may have six or more large tan spots on the skin. Such spots may increase in size and number and become darker. Small benign tumors called neurofibromas may occur under the skin or in the muscles. They are made up of nerve cells and other cell types. NF is a dominant disorder. Jane has NF and wants to figure out what the chances are that her children will inherit the disorder if her husband, John, does not have NF.
  1. The condition of sickle cell anemia is recessive and only the homozygous recessive individuals are adversely affected. Interestingly, heterozygous individuals have increased resistance to Malaria which is caused by a Plasmodium parasite that infects red blood cells. A heterozygous individual has red blood cells that are minimally affected but are altered enough so that Plasmodium cannot infect the cells. This is one reason why this allele persists in the population – in the heterozygous state it gives the individual an advantage for survival in some environments.

Veronica, who has the sickle cell condition, and Mason who does not have the condition have a child. They are worried about the having a child with sickle cell anemia and malaria because they are moving to a part of Africa where the Plasmodium is common. Who in this family should be worried about sickle cell anemia and contracting malaria?

  1. All newborn babies are tested to see if they have a defective enzyme which cannot break down the amino acid phenylalanine. If phenylalanine accumulates in the blood then high levels can cause mental retardation. The condition is called phenylketonuria or PKU. PKU is a recessive allele and only homozygous recessive individuals are affected. A family living in a country where PKU testing is not done wanted to know if they should have their baby in the US. The pregnant mother has a parent who has the PKU condition and the father also has one parent with the condition. Neither the pregnant mother nor the father has the condition. Draw a punnett square demonstrating the likelihood that this new baby will inherit PKU and discuss why or why not the parents should have the baby in the US. (K = dominant, non-disease allele; k = recessive, disease allele)
  2. Huntington’s disorder is caused by a dominant allele. Heterozygous individuals with one copy of this allele suffer from progressive degeneration of the nervous system and premature death. The phenotype or symptoms do not appear until the affected individual reaches ~40 years of age. This is after child-bearing age, so people have children before they know they are carrying the affected gene allele.

Jermaine is very worried about passing the dominant Huntington’s gene allele to his children. If Jermaine’s father has the Huntington’s Disorder, his mother does not, and his wife has no history of Huntington’s, does Jermaine need to be tested for Huntington’s before he has children? Note: homozygous dominant is lethal and a fetus will not survive. Draw a punnett square representing the Jermaine’s father and mother, to determine his chances of carrying the Huntington’s disease allele. (H = dominant, disease allele; h = recessive, non-disease allele)

What is the probability that Jermaine has the Huntington’s disease allele? Should he be tested?

If Jermaine is positive for the Huntington’s allele, what are the chances he will pass it on to his children? Do a second punnett square to illustrate this cross.

John, 38, makes $125,000 per year. He has a 35 year old wife, Nancy, and a daughter who just turned 7. John’s share of the family’s consumption is 21%, and he pays an average tax rate of 28%. He plans to work another 30 years and expects salary increases equal to inflation, which he expects to be 3% annually. He expects to earn an 8% nominal rate of return on his investments.

1. Use the Human Life Value (HLV) method to calculate John’s appropriate amount of life insurance coverage.
