Activity 9 Homework Answer Key Essay
Review Chapter 8 and pages 160–162 of Chapter 9 in Biology, 7th edition. Then complete the discussion by supplying or choosing the appropriate terms.
To maintain life, organisms must be able to convert energy from one form to another. For example, in the process of photosynthesis, algae, plants, and photosynthetic prokaryotes use the energy from sunlight to convert carbon dioxide and water to glucose and oxygen (a waste product).
The summary reaction for photosynthesis can be written as
6 CO2 6 H2O C6H12O6 6 O2
This type of reaction is an oxidation-reduction (or redox) reaction. This reaction is also [anabolic/catabolic] and [endergonic/exergonic].
In redox reactions, …show more content…
Use the pieces you assembled to model the processes of fermentation and aerobic respiration. Develop a dynamic (claymation-type) model that allows you to manipulate or move glucose and its breakdown products through the various steps of both fermentation and aerobic respiration.
When you feel you have developed a good working model, demonstrate and explain it to another student.
Be sure your model of fermentation includes and explains the actions and roles of the following:
glycolysis cytoplasm electrons protons glucose
pyruvate ethyl alcohol (or lactic acid) substrate-level phosphorylation
Be sure your model of cellular respiration includes and explains the actions and roles of the following:
glucose oxygen carbon dioxide pyruvate acetyl CoA
water electron transport chain mitochondria inner mitochondrial membrane outer mitochondrial membrane
electrons (e) chemiosmosis ATP synthase (proton pumps) cristae proton gradients oxidative phosphorylation substrate-level phosphorylation oxidative phosphorylation
Use your models to answer the questions.
