Unit 2 – Energy Transfers – Metabolism, Enzymes, Photosynthesis, Fermentation, and Respiration

Essential Questions:

How is energy stored in living systems?
How is energy transferred within and between living systems?
How do the laws of thermodynamics apply to living systems?
What is free energy?
In what form is energy stored and used in living systems?
How are energy transfers facilitated in living systems?
How does the shape of an enzyme relate to its function?
How do cells modify and control metabolic activities?
How does the sun power living systems?
How is sunlight energy captured and converted into chemical bond energy.
How is chemical bond energy of fuel molecules release in manageable amounts and forms?

Objectives:

Describe how energy is stored and released from chemical bonds.
Define the laws of thermodynamics and discuss how they apply within living cells.
Define free energy and discuss how life depends on the availability of free energy.
Illustrated the ATP / ADP + P + energy cycle.
Discuss energy coupling.
Explain the function of enzymes.
Discuss the limitations of enzymes.
Highlight the relationship between the structure of the enzyme and its functioning.
Discuss metabolic control.
Emphasize plant and other photosynthetic organisms role in the overall energy systems of living things on earth.
Explain the processes of photosynthesis in detail. Relating the processes to the previous discussion on energy.
Explain chemiosmosis in detail. How do the structures and properties of membranes play a role in this process?
Illustrate the cyclic nature and interdependence of these processes.
Discuss and illustrate alternative pathways for carbon fixation in plants.
Describe fermentation and respiration in detail.
Relate the processes of respiration to photosynthesis.
Discuss the role of these energy releasing pathways to the interdependence of organisms.
Highlight the role enzymes and membranes, free energy, and properties of water play in these processes.
