2
There are two types of cellular respiration. What are they?
glycolysis and the Calvin cycle
mitosis and meiosis
transcription and translation
aerobic and anaerobic
3
In plant leaves, O
2
output decreases as CO
2
(the substrate in photosynthesis) levels. This suggests that _____.
Batman is in the building.
substrate inhibition is happening.
fermentation has stopped
the plant leaf cell mitochondria have exploded
4
A plant in the sunlight can do _____.
lactic acid fermentation and glycolysis
glycolysis and Calvin cycle only
the light dep. reactions, Calvin cycle, and fermentation
the light dep. reactions, Calvin cycle, aerobic respiration
5
Kimchi and yogurt are two foods that contain this when cells present do not get enough oxygen
glucose
lactic acid
carbon dioxide
alcohol
6
What is the "food" most often used by cells to generate ATP for their energy needs?
ADP
glucose
nucleic acids
methane
7
This image summarizes _____.
photosynthesis
anaerobic cell respiration
lactic acid fermentation
fermentation
8
What is an autotroph?
an organism that can "do" photosynthesis
plants, for example
an organism that "makes" its own food
all of these
9
Most enzymes end with this suffix.
-able
-tonic
-ose
-ase
10
Kimchi and other fermented foods are possible because of this biochemical process
anaerobic respiration
both fermentation and anaerobic respiration
neither fermentation nor anaerobic respiration
fermentation
11
This graph shows enzyme activity is influenced by _____.
temperature
pH
substrate inhibition
substrate concentration
12
What goes in box G? This image appears in the PPT slides for lecture 6.
CO2
sunglight
ATP
C6H12O6
13
Plants do photosynthesis to make food. Do plant cells undergo cell respiration, too?
Yes
Yes, but only at night
No
Yes, but only if there is enough CO2 in the atmosphere
14
What is a heterotroph?
plants
organisms that use sunlight to synthesize carbohydrates
all of these
an organism that can not use photosynthesis to make food
15
The "holes" of most plant leaves that water vapor, O
2
, and CO
2
use to enter/exit plant cells
chlorophyll
thylakoids
chloroplasts
stomata
16
What enzyme substrate was used in our recent lab activity examining photosynthesis?
C6H12O6
H2O
CO2
artificial light (not sunlight)
17
Both aerobic and anaerobic respiration explain how our cells make ___ to meet our energy needs.
all of these
CO2
ATP
glucose
18
The light dependent stage of photosynthesis includes this important reaction.
CO2 is released from stomata after sugar is made
CO2 is split apart by photons of light
C6H12O6 gets assembled from rubisco
light splits H2O apart releasing O2 into the atmosphere
19
What is a product of photosynthesis that is used as a reactant for aerobic respiration?
chlorophyll
CO2
O2
H2O
20
Cells responsible for helping us make kimchi are _____.
photosynthetic
autotrophic
prokaryotic
none of these is correct
21
We know this equation shows an anaerobic process. How?
no oxygen is shown as part of the equation
NAD+ is produced
pyruvic acid is shown as three little red balls
lactic acid is sour
22
How do glucose molecules you eat during a meal eventually get inside one of your brain cells?
osmosis
through facilitated diffusion
simple diffusion directly across the phospholipid bilayer
glucose just walks in the brain cell like it owns the place
23
Ribulose biphosphate carboxylase oxygenase
This is an enzyme
Is responsible for carbon fixation during the Calvin Cycle
all of these
This is also called RUBISCO
24
The two types of anaerobic respiration are _____.
the light dependent and the light independent reactions
aerobic and anaerobic
fermentation and the Calvin cycle
lactic acid fermentation and alcohol fermentation

glycolysis
27
The CO
2
released by your cells comes from this part of aerobic cellular respiration.
the Calvin cycle
glycolysis
the Krebs cycle
electron transport
28
Enzymes work generally by breaking down molecules. These molecules being broken down are called _____.
Batman
inhibitors
substrates
RUBISCOs
29
The molecule sometimes called the "energy currency" for a cell is _____.
RNA
thymine
ATP
DNA
30

lay in the sunlight for 20 minutes
drink more enzymes
eat food to supply cells with C6H12O6
study biology more often
