Cellular Respiration
There are two types of cellular respiration.
Cellular respiration that occurs in the
presence of oxygen is called Aerobic
respiration and it occurs in mitochondria.
Cellular respiration that occurs in the
absence of oxygen is called Anaerobic
respiration and it occurs in a cell’s
cytoplasm.
How Cellular Respirations
Works
C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy
Cellular Respiration is really just the
reverse of photosynthesis.
And it occurs in all organisms, both
autotrophs and heterotrophs.
It is how glucose (sugar) gets broken
down into usable energy (ATP).
How Photosynthesis Works
Energy + 6CO2 + 6H2O → C6H12O6 + 6O2
Photosynthesis takes place in chloroplasts.
Inside the chloroplasts are flat sac-like
structures called Thylakoids.
Thylakoids are arranged in stacks of other
thylakoids called Grana.
The light-dependent reactions occur in the
Grana. (Photosystems I and II).
Key Elements
Chloroplasts -
Organelles found only
in plant cells that carry
out photosynthesis.
Mitochondria -
Organelles found in
plant and animal cells
that carry out cellular
respiration.

Summary
Photosynthesis and cellular
respiration are related.
Photosynthesis occurs in the
chloroplast of plant cells.
Cellular respiration occurs in
the mitochondria of plant and
animal cells.
Whenever you see an arrow in
our equations, think “produces”.
Reactants produce products.
Remember, what one produces
the other one needs. It is a
cycle.
