4. Respira�on is a _______________
reac�on in which sugar
is oxidized to produce energy.
5. The energy produced by respiraton is the in the form of
ATP
adenosinetriphosphate or __________.
6. The reactants and products for respira�on are exactly the
same for a plant cell and an animal cell, the difference is
source
the ____________
of the reactants.
7. What is the rela�onship between the chemical reac�on for
photosynthesis and the chemical reac�on for respira�on?
They are opposite reac�ons. The raw materials for one
reac�on are the products of the other reac�on.
8. Although plants produce and release oxygen during
photosynthesis, they also require it. Why?
Plants give off oxygen during photosynthesis, but they also
need oxygen for cellular respira�on to turn sugar into e
energy.
9. What is the chemical equa�on (balanced!) for cellular
respira�on?
C₆H₁₂0₆ + 6O₂ → 6CO₂ + 6H₂O + Energy
