“For each of us, this is a problem of interrelationships, of interdependence—essentially, of ecology. … But there is also an ecology of the world within our bodies.” -Part 3 of the serialized New Yorker publication of Silent Spring. Explain why the interrelationships in ecology in nature and the “ecology of the world within our bodies” are each important components of Carson’s critique.

Based on historical context provided by the documentary American Experience: Rachel Carson, give the counterpoint to Rachel Carson’s argument that synthetic pesticide use in the early 1960s imposed more risks than benefits. What were some of the benefits of the synthetic pesticide use at the time? What alternatives does Carson propose to the use of chemicals? Do you think these alternatives make sense in the context of agribusiness?

What type of molecules are enzymes? Where are they found? How do they work? What are their limitations?

Essay Questions:

Enzymes can be described as biological catalysts that regulate the rate of chemical reactions involved in biological processes. Different types of chemical reactions are catalysed by different classes of enzyme.

Describe and discuss some of the chemical reactions that enzymes facilitate in photosynthesis and cellular respiration.

In your introductory paragraph(s) you might give a brief overview of what an enzyme is.

A cell with a normal concentration of 0.9% carbon dioxide is placed in a solution of 4% carbon dioxide. Carbon dioxide molecules are small, so they can diffuse through the membrane. Which way will they diffuse? Click or tap here to enter text.

Carbon dioxide is a waste product that is produced in the production of cellular ATP and needs to be continually removed from cells. In reference to the previous question, what process would the cell use to maintain a low concentration (~0.9% CO₂) of carbon dioxide? Click or tap here to enter text.

A cell with a normal concentration of 2% starch is placed in a solution of 28% starch. Starch molecules are too large to diffuse through the cell membrane. Which direction will the water move (into or out)?

Calcium is an essential plant nutrient that plays an important role in the structure of plant cell walls and membranes, calcium (Ca²+) also serves as an obligate intracellular messenger. A certain plant cell requires a concentration of 80% calcium, it currently has only 70% calcium. The extracellular fluid contains 30% calcium, will the cell require energy to obtain enough calcium to function? Why?

A Euglena (protozoan) that normally lives in saltwater (3.5% salt) is placed in freshwater (0.8% salt). If osmosis occurs, what will happen to the cell right away?

What will eventually happen to the cell?

Algae are plant-like aquatic protists. An algal cell that normally lives in saltwater (3.5% salt) is placed in a solution of 0.% salt. If osmosis occurs, what will happen to the cell?

What cell feature (cell part) prevents it from bursting?

What will happen to plant cells when providing sufficient water for growth (hypotonic solution)? What is this called (be specific)?

Plants require water for photosynthesis. This is what makes them autotrophs (capable of feeding themselves). During a drought the soil water concentration is lower than the concentration of water in the root cells of the plant. In which direction will osmosis occur?

What happens to the appearance of the plant?

Explain on what and how the condition is caused. highlight the different forms of Cushing’s disease and tests that the patient will have to undergo to determine the which form the patient has.

2 Biochemistry Case Studies

Marks are awarded as follows:

Biochemical abnormalities (30%): A good interpretation of a case study or good explanation of the biochemical basis of the disease. Extensive links between analyte levels and pathophysiology/patient symptoms.

Evaluation (40%): Extensive and excellent selection of peer-reviewed articles used to support a good outstanding evaluation.

Communication (20%): Good quality of scientific writing.

Referencing (10%): Good Harvard style referencing from peer-reviewed sources and literature. Citations and references formatted correctly.

Question 2 is case study heavy and my suggestion is that it describes a patient with Cushing’s disease.

There should be a clear show of how the case study results indicate a patient with Cushing’s disease, but this should not be concluded early. A show of process of how you came to the diagnosis should be shown.

Explain on what and how the condition is caused. highlight the different forms of Cushing’s disease and tests that the patient will have to undergo to determine the which form the patient has.
