UCSD BILD 1: The Cell Section, Week 5 UCSD BILD 1: The Cell Question 1 This is a graph of the rate of reaction vs. the pH for the protein pepsin, an enzyme that breaks down protein in the human stomach. The human stomach is very acidic (low pH). Another protein that breaks down protein, trypsin, is in the human small intestine. The pH of the small intestine is slightly basic, around pH 8.
On the same graph, please draw the predicted rate of reaction vs. pH for trypsin.
Question 2 Your study friend tells you, “
The oxygen you inhale does not automatically become part of your dry biomass.
” Would you agree or disagree with this statement, and why? (suggestion: 1-3 sentences) Question 3: A man who worked is experiencing an illness with many symptoms, including muscle weakness. His mother alleges that his wife is poisoning him, and you are assigned to investigate. A doctor’s visit shows mitochondrial damage. Levels of key molecules are as follows:
a.
You learn that the wife’s parents used to be woodworkers, so in their old shed, she has access to arsenate, which used to be used to preserve wood until it was banned for being toxic. Arsenate inhibits glycolysis. Are the medical results consistent with arsenate poisoning? Justify your reasoning. (roughly 1-2 sentences) Molecule Level compared to normal Pyruvate High Acetyl Co-A Low NADH Low Rate of reaction à
UCSD BILD 1: The Cell Section, Week 5 UCSD BILD 1: The Cell b.
The man missed his childhood home, and he had his mother ship him water from their well, which he drinks almost exclusively. (His mother only drinks Coke.) You find that the water has naturally very high levels of arsenite, which mainly inhibits the transition reaction. Are the medical results consistent with arsenite poisoning? Justify your reasoning. (roughly 1-2 sentences) c.
In his job, the man used to spread sodium fluoroacetate to combat mice. Sodium fluoroacetate only inhibits the citric acid cycle. Are the medical results consistent with sodium fluoroacetate poisoning? Justify your reasoning. (roughly 1-2 sentences) d.
The couple previously had a flea problem in their house, so the wife had access to a store of the pesticide rotenone. Rotenone only inhibits the electron transport chain. Are the medical results consistent with rotenone poisoning? Justify your reasoning. (roughly 1-2 sentences)

Q.12. Each of the following statements is true about some or all organisms on planet earth. Which is the most fundamental – most basic, complete, general and accurate – statement about what distinguishes all organisms from all non-organisms?
1.Organisms are entities which contain chemically encoded information and chemical tools designed to assist in the chemical replication of that information.
2.Organisms require cooperation of conspecifics to reproduce.
3.ORGANISMS REQUIRE EXTERNAL ENERGY SOURCES TO SUSTAIN THEIR NON-EQUILIBRIUM STATUS.
4.The information designing organisms is prone to error in its replication as a result of the Second Law of Thermodynamics.

3. A group of students wants to study the effects of temperature on bacterial growth. To get bacteria, they
leave petri dishes of nutrient agar open on a shelf. They then put the dishes in different places: an
incubator (37 degrees C) a lab room (21 degrees C), a refrigerator (10 degrees C) and a freezer (0 degrees
C). Bacterial growth is measured by estimating the percentage of each dish covered by the bacteria at the
end of a three day growth period.
a) What is the independent variable?
b) What is the dependent variable?
c) List two (or more) ways to improve this experimental design.
