A. Mitochondrion
A. CO2; ATP; Hydrogen ions
(protons)
Q. Explain the role of ADP in relation
to the small amount of energy
released during the first stage of Q. For what is ATP an abbreviation?
respiration.
A. First stage uses energy,
combines with phosphate, to form
ATP. ATP stores energy in high
energy bond
Q. What is the first stage process of
respiration called?
A. Adenosine Triphosphate
Q. The electrons released in Kreb's
Cycle pass along a transport chain
and release energy. To what use is
this energy put?
A. To form ATP
A. Glycolysis
Q. What is the final product of the
first stage of respiration under
aerobic conditions?
Q. To what are the electrons
transferred at the end of the
electron transport chain in aerobic
respiration?
A. Pyruvic acid (Pyruvate)
A. Oxygen; H+ (protons)
Q. If conditions in a human muscle
cell become anaerobic pyruvic acid
is converted to another substance.
Name this other substance.
Q. Where in the cell does the first
stage of respiration occur?
A. Cytoplasm
A. Lactic acid
Q. In Stage 2 of respiration
Q. To what is pyruvic acid (pyruvate)
electrons pass along an electron
converted under anaerobic
transport chain, releasing energy. In
conditions in yeast?
what molecule is this energy stored?
Page 1 of 4
A. Ethanol & CO2
A. ATP
Q. Under aerobic conditions
pyruvate is converted to an acetyl
group and a small molecule is
released. Name this small molecule.
Q. Name the group of protein
molecules that control the rate of
respiration.
A. Carbon dioxide
A. Enzymes
Q. In the first stage of respiration
there is a release of ATP as glucose
is converted to another substance.
Name this other substance.
A. Pyruvic acid (pyruvate)
Q. In aerobic respiration the acetyl
group enters a cycle of reactions.
What name is given to this cycle?
Q. What is fermentation?
A. Anaerobic respiration;
Respiration that produces lactic
acid or ethanol & CO2
Q. Is oxygen required for the first
stage of respiration?
A. Krebs cycle
A. No
Q. Name a compound to which
pyruvate (pyruvic acid) may be
converted, in the absence of
oxygen.
Q.
C6H12O6 + 6O2  ENERGY + 6CO2 + 6H2O
Is this the equation for
photosynthesis or respiration?
A. Lactic acid; Ethanol & CO2
A. Respiration
Q. In what part of the cell does the
second stage of respiration take
place?

Q. How did you know that
fermentation had ceased?
A. Mitochondrion
A. Bubbling stopped
Q. In the mitochondrion pyruvate is
broken down to CO2 and a twoQ. Is oxygen required for the second
carbon compound. Name this twostage of respiration?
carbon compound.
A. Acetyl Co-enzyme A
A. Yes
Q. Give one product, other than
electrons, of the reactions in Kreb’s
cycle.
Q. Where does Kreb’s cycle take
place?
