Chapter 9
Cellular Respiration
Life is Work
Compare and contrast energy and
chemical elements in the environment and
organisms
Describe the interaction between
photosynthesis and cellular respiration
– Name the organisms using with each process
Catabolic Pathways
Describe the two types of catabolic
pathways
Discuss why the study of glucose
catabolism is important
Redox Reactions
OIL RIG
Describe redox reactions and their effect
using reactions in the environment and in
cells
Compare and contrast redox reactions of
engines and cells
NAD+
and the Electron Transport Chain
Describe the changes undergone by NAD+
in cellular respiration
– Explain their significance
– Explain what enables the reactions
Describe the electron transport chain
Describe the movement of electrons from
the fuel molecules to the terminal electron
acceptor
Cellular Respiration
Describe the steps of cellular respiration
and their locations
Distinguish between oxidative and
substrate-level phosphorylation
– Describe the reactions in which each takes
place
Discuss the energy efficiency of cellular
respiration
Glycolysis
Outline the process and products of
glycolysis
Discuss glycolysis stressing the changes
in glucose that result from energy
investment and lead to energy release
Describe the end products of glycolysis
and their energy content
Citric Acid Cycle
List the products of the citric acid cycle
Describe the source of carbons in CO2
and the fates of acetyl carbons
Describe where the enzymes of the citric
acid cycle and their locations
Describe how energy is released and
trapped in the citric acid cycle
Electron Transport Chain
Describe the location and components of
the electron transport chain
Discuss the differences between NADH
and FADH2 in relation to the ETC
Discuss how much ATP has been formed
by the ETC
Discuss the role of oxygen in energy
release
Evolution Connection p. 180
Chemiosmosis
Define chemiosmosis
– Differentiate it from osmosis
Describe the location and action of ATP
synthase
Define proton-motive force
Describe how chemiosmosis is used in
eukaryotes (both plants and animals) and
prokaryotes
Scientific Inquiry p. 180
Accounting in Cellular Respiration
Make a table showing the source and
location of energy released and the forms
in which the energy is found
Describe 3 factors preventing exact
knowledge of ATP production due to each
step of cellular respiration
Fermentation
Differentiate between aerobic and
anaerobic respiration
Describe the types of fermentation and the
advantage of fermentation
Describe the evolutionary significance of
glycolysis
Science, Technology, and Society p. 180
Versatility
Describe how different foods are used in
catabolism
– Compare their pathways and energy release
Describe how the body obtains monomers
and the carbon backbones it needs
Metabolic Regulation
Describe how feedback mechanisms
regulate metabolism
Name the pacemaker of respiration and
describe its control
