Chapter 6: Energy for Life

General Instructional Objectives (GIOs)

  • Explain the importance of the surface area to volume ratio in cells i.e. explain and model why cells are small. (Claim 4).

  • Summarize the process of protein synthesis using specific organelles (Cytosis game).

  • Explain the importance of cell communication in yeast cells. (Claim 5).

  • Section 6.1. Understand how energy is central to life.

  • Section 6.2. Understand the nature of energy.

a. define energy.

b. understand the difference between kinetic and potential energy. Note: there are NOT 'kinds' of energy like there are kinds of candy bars...energy is energy...the only difference between 100 J of chemical energy and 100 J of nuclear energy is where it is stored.

c. be able to apply the laws of thermodynamics to living systems.

  • Section 6.3. Explain how energy is used in living organisms.

a. provide examples of exergonic and endergonic reactions.

b. define coupled reactions and provide examples.

  • Section 6.4. Understand the importance of ATP

a. Explain the ATP/ADP cycle.

b. Explain why ATP is the 'energy dispensing molecule' of life.

  • Section 6.5. Understand the critical importance of enzymes in living organisms.

a. define enzyme and explain how they function (what they do and do not do).

b. be able to diagram how enzymes function.

c. explain why enzymes are called catalysts.

d. using chymotrypsin as an example, explain how enzymes work.

  • Section 6.7. Explain how enzymatic activities are regulated (inhibition, regulation, feedback).

  • Summarize and model the impact environmental factors have on enzyme activity. (Claim 6)
