Study Guide for Test 3

Chapter 7

1. Know the ultimate source of energy for almost all living organisms.
2. Know the following terms: energy (both kinetic, potential, and chemical), mass, entropy, enthalpy, catabolism, anabolism, metabolism, dynamic equilibrium, endogonic reactions, and exogonic rections.
3. Know the 1st and 2nd Laws of Thermodynamics and their applications.
4. Know how a cell maintains a high degree of order.
5. Know how endogonic and exogonic reactions are coupled. Know how ATP stores energy.
6. Know how electrons/proton transfer transfers energy in redox reactions. Know the molecules that are involved in energy transfer in redox reactions.
7. Know how enzymes function as catalysts, including induced fit, active sits, allosteric sites, allosteric regulation, cofactors, and apoenzymes.

Chapter 8

8. Know, in detail, glycolysis and citric acid cycle. This includes the molecules involved, the names of the molecules, the names of enzymes involved, and energy molecules involved. Be able to fill in each on a blank chart.
9. For extra credit, know in detail the formation of acteyl CoA from pyruvate.
10. Know in detail the electron transport chain of mitochondria. Know the function and process of chemiosmosis.

Chapter 9

11. Know the order of electromagnetic radation, from shortest wavelength to longest.
12. Know how a photon can energize an electron. Know how chloroplasts use this to gain energized electrons for their electron transport chain.
13. Know the composition of chlorophyll, particularly the inorganic atom at its center.
14. Know the parts of the chloroplast and their functions.
15. Know the parts of the leaf and their functions.
16. Know the overall reaction of photosynthesis and which molecules are reduced and which are oxidized.
17. Know, in detail, the light dependant and carbon-fixation reactions. Know where each reaction takes place. Know the reactants and products of both sets of reactions.
18. Know the difference between C3, C4, and CAM plants. Know how each type of carbon-fixation reaction differs.
19. Know the various trophic groups and examples of each.
