Quarter 2 ExamPractice Questions
Respiration
Name anaerobic respiration with yeast that produces Ethyl alcohol.
Alcoholic fermentation
The Energy of glucose is transformed to this.
ATP
NADPH and FADPH
Protein molecules that carry electrons
The step of respiration where 24 electrons are released and picked up by NADP and FADPH?
The Kreb’s Cycle
List what is inside of a respirometer.
*Cotton with KOH *nonabsorbant cotton
*organism being tested
Which animal would be affected most by temperature
changes?
Mouse, turtle, human, dolphin
Turtle
An acetyl group is formed in which step of
respiration?
Pyruvate Oxidation
What is incorrect in the reaction of respiration
below?
C6H12O6 + 6CO2 6H2O + 6O2 + 34 ATP
C6H12O6 + 6 O2 6H2O + 6CO2 + 36 ATP
What is “A” and “B” in the diagram?
A
B
A= MatrixB= Cristae
Compare the amount of ATP formed from one glucose molecule during aerobic and anaerobic respiration.
Aerobic respiration= 36 ATP
Anaerobic= 2 ATP
How is ATP formed from Chemiosmosis?
H+ ions are pumped across the
cristae membrane forming a gradient.
The H+ them diffuse back into the
cristae through ATP Synthase
proteins….where ADP is phosphorylized making ATP.
What products of respiration
are needed for photosynthesis?
Carbon dioxide and water.
What is a product of anaerobic respiration in muscle cells?
Lactic Acid
Photosynthesis
Type of plants, like desert plants close stomates during the
day to conserve water.
CAM Plants
Accessary pigments found in all green plants.
Carotenoids
When is carbon dioxide utilized in the
process of photosynthesis?
In the Dark reaction in the Calvin Cycle
Where does the energy come from in order to drive the C3
Cycle?
A little ATP from the Light
Reaction
Most of the ATP from Respiration
p680 and p700(photocenters)
Why is C3 photosynthesis called Carbon fixation? What
is the source of the carbon?
It is called carbon fixation because carbon is taken in as CO2 and used to make organic
molecules.
Chlorophyll a absorbs light of what
color and wavelength?
Color= red at 625-650 nm
Color= blue at 425-450 nm
What is the name for light energy?
Photons
What affects separation of pigments during chromatography?
Solvent used, medium used, capillary action and amount of pigment used
Why was DPIP used in the lab of rate of photosynthesis?
DPIP replaced NADPH in the reaction and is reduced (becomes more colorless) as photosynthesis occurs.
What is labeled as “A” and “B” in the diagram?
A B
C
A= Grana
B=Stroma
