What is the goal of cellular respiration?
10 pts Cellular Respiration
To produce energy from food you eat by breaking
chemical bonds
Cellular respiration takes place in what
organisms?
20 pts Cellular Respiration
Cellular respiration takes place in plants, animals,
fungi, protists and most bacteria
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
What is the balanced equation for cellular
respiration?
40 pts Cellular Respiration
6O2 + C6H12O6  6CO2 + 6H2O + Energy
What does anaerobic mean?
10 pts Cellular respiration II
Without the presence of oxygen
In what part of the cell does glycolysis
occur?
20 pts Cellular respiration II
Glycolysis occurs in the cytoplasm of the cell
What pathway of cellular respiration is
anaerobic?
30 pts Cellular Respiration II
Glycolysis
What are the pathways of cellular
respiration that are aerobic, and where do
they occur?
40 pts Cellular Respiration II
1. Krebs cycle and electron transport chain
2. Occur in the mitochondria
In what organelle does photosynthesis take
place? 10 pts Photosynthesis
The chloroplast
What are the membranes that capture light
energy for photosynthesis?
20 pts Photosynthesis
Thylakoid membranes
What is produced in photosynthesis?
30 pts Photosynthesis
Glucose, and oxygen as a byproduct
What is the overall balanced equation for
photosynthesis
40 pts Photosynthesis
6CO2 + 6H2O  C6H12O6 + 6O2
light
What pigment absorbs light energy?
10 pts Photosynthesis II
Chlorophyll
True or False: Only plants can perform
photosynthesis
20 pts Photosynthesis II
False – plants, fungi, and some bacteria can
photosynthesize
Where do light-independent reactions take
place in the chloroplast?
30 pts Photosynthesis II
Stroma (the fluid-filled space in the chloroplast)
What 3 things are required for lightdependent reactions?
40 pts Photosynthesis II
Light, chlorophyll, water
Fermentation occurs in the same place in
the cell as glycolysis, which is…
10 pts Fermentation
The cytoplasm
How is fermentation different from cellular
respiration?
20 pts Fermentation
Fermentation does not require oxygen, doesn’t
occur in mitochondria (takes place in
cytoplasm)
What are the two general kinds of
fermentation
30 pts Fermentation
Alcoholic fermentation and lactic acid
fermentation
What kind of fermentation results from
strenuous exercise?
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”
