What is the goal of cellular respiration?
10 pts Cellular Respiration
To produce energy from food you eat by
breaking chemical bonds (#1)
True or False: Cellular respiration only takes
place in plants
20 pts Cellular Respiration
False – cellular respiration takes place in
plants, animals, fungi, protists and most
bacteria (#12)
How are photosynthesis and cellular
respiration related?
30 pts Cellular Respiration
Photosynthesis and cellular respiration are
opposing processes. Reactants of one are
products of the other, and vice versa.
(not on worksheet – on studyguide for final)
What is the balanced equation for cellular
respiration?
40 pts Cellular Respiration
6O2 + C6H12O6  6CO2 + 6H2O + Energy
(not on worksheet – add it!)
Glycolysis is anaerobic. What does
anaerobic mean?
10 pts Glycolysis
Without the presence of oxygen (#10)
In what part of the cell does glycolysis
occur?
20 pts Glycolysis
Glycolysis occurs in the cytoplasm of the cell
(#8)
What is the product of glycolysis?
30 pts Glycolysis
PYRUVIC ACID (#1 from 9.2)
What are 2 advantages of glycolysis?
40 pts Glycolysis
1. Glycolysis can produce ATP very fast if
the cell’s energy needs suddenly
increase
2. It can still supply energy when oxygen is
not available (#5 from 9.2)
In what organelle does the Krebs cycle take
place? And in what specific place in this
organelle?
10 pts Krebs Cycle
The mitochondria – specifically the matrix,
the innermost compartment (#7)
What is another name for the Krebs cycle?
20 pts Krebs Cycle
The citric acid cycle (#7)
True or False: The Krebs cycle is aerobic (it
requires oxygen)
30 pts Krebs Cycle
True (only glycolysis can occur in the
absence of oxygen) (#9)
What is the reactant (what is needed) for
the Krebs cycle, and what is the product ?
40 pts Krebs Cycle
Pyruvic acid is the reactant (needed)
Through a series of reactions, citric acid is
produced
(#2, #8)
What is the molecule needed for the
electron transport chain to transform
energy?
10 pts Electron Transport Chain
High-energy electrons convert ADP  ATP
(#9)
What is the special electron carrier that
takes high-energy electrons from glycolysis
to the electron transport chain?
20 pts Electron Transport Chain
NAD+ (which is converted to NADH)
(#3)
True or False: Most energy for cellular
respiration is generated in this stage
30 pts Electron Transport Chain
True (#5.3 from 9.1)
By the end of the electron transport chain
(and thus, the end of 1 round of cellular
respiration), how many molecules of ATP
have been generated?
40 pts Electron Transport Chain
36 molecules of ATP are produced in 1 round
of cellular respiration
(#10)
Fermentation is a process similar to cellular
respiration, except that it occurs without the
presence of oxygen. What word means
“without the presence of oxygen”?
10 pts Fermentation
Anaerobic
Fermentation occurs in the same place in
the cell as glycolysis, which is…
20 pts Fermentation
The cytoplasm
Some microorganisms like THIS unicellular
eukaryote undergo alcoholic fermentation,
which is used to produce alcoholic
beverages and also makes bread dough
rise
30 pts Fermentation
Yeast
This other kind of fermentation is a result of
strenuous, extended exercise, and named
for the type of acid that is produced by the
body (not sure? Take a guess!)
40 pts Fermentation
Lactic acid fermentation – if you’ve ever run
so hard your muscles burn, it’s because
the lactic acid in your muscles has built up
due to lack of oxygen in your body
9.3 Fermentation

•
Similar to cellular respiration
Anaerobic (without oxygen)
Takes place in the cytoplasm of the cell
2 types
– Alcoholic fermentation – Ex: yeast – makes
bread dough rise, alcoholic beverages
– Lactic acid fermentation – occurs in humans
during exercise when your body is short on
oxygen; makes muscles “burn”
