Chapter 48.2, Problem 5SAQ
Summary Introduction
The presence of CO2 in the atmosphere is higher and increased day by day by the burning of fossil fuels. According to the Keeling curve, the levels of CO2 have increased dramatically over the past 60 years. Apart from natural CO2 emission like volcanos, human are the major contributors to increase CO2 dramatically by burning fossil fuels, deforestation, and industrial revolutions

3. Shown below is the dental formula and digestive tract anatomy of three mammalian species
(A, B, and C). What kind of diet would you expect each species to have? Support your
answers with what you can infer from the dental formula and what you can see in the
diagram. Broadly speaking, what accounts for the differences?

6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in
relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in
diving humans.
• How might the location and slope of the O2 line differ for diving marine mammals such as
whales and dolphins?
•
How might the location and slope of the CO2 line differ for diving marine mammals such as
whales and dolphins?
•
•
Draw in predicted lines for O2 and CO2, based on your reasoning above.
How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line
differ for diving marine mammals?
What physiological mechanisms account for each of these differences, resulting in the ability
of marine mammals to stay submerged for long periods of time?
How much ATP will be produced during the following metabolic scenario:
Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid. Recall that when glycerol breaks down to Glyceraldehyde-3-phosphate it costs one ATP but your get an extra FADH2. Every two carbons of a fatty acid break down to one acetyl-CoA.
Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.

- When beta-lactamase was isolated from Staphylcoccus aureus and treated with a phosphorylating agent, only the active site, serine was phosphorylated. Additionally, the serine was found to constitute 0.35% (by weight) of this beta-lactamase enzyme. Using this, calculate the molecular weight of this enzyme and estimate the number of amino acids present in the polypeptide.arrow_forwardBased on your results from the Mannitol Salt Agar (MSA) media, which of your bacteria were mannitol fermenters and which were not mannitol fermenters?arrow_forwardhelp tutor pleasearrow_forward
- Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
