Part Three: Acid/Base Homeostasis in the Human Body
Beginning Questions:
Carbon dioxide is formed during cellular respiration and then diffuses out of cells into the interstitial fluid and then into the bloodstream. Most of the carbon dioxide is transported in our blood as bicarbonate. Write the chemical equation for the formation of bicarbonate and hydrogen ions from carbon dioxide and water below.
Under which of the following situations would the formation of bicarbonate and hydrogen ions be greater? Circle your answer.

*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.
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?
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.
