COMMON MISCONCEPTION: Plants DO NOT get energy from photosynthesis. Rather, they use light
energy to build sugars. They then use the sugars to build ATP via cellular respiration (just like animals).


Mitochondria: site of cellular respiration in
eukaryotic cells.
Glucose: energy source broken down to
release ATP.
NADH & FADH2: coenzymes that shuttle
electrons from glycolysis and Krebs cycle to the
electron transport chain.
Glycolysis: begins the breakdown of glucose
into 2 molecules of pyruvate (occurs in
cytoplasm of cell).
Intermediate Step: converts pyruvate into
Acetyl CoA, which enters the Krebs cycle.
Krebs Cycle: completes the breakdown of
glucose, produces ATP, NADP, and
FADH2…occurs in the mitochondrial inner
matrix.
CO2: waste product released during cellular
respiration.
O2: final electron acceptor for the electron
transport chain.
Electron Transport Chain: uses energy
extracted from glucose to produce ATP by an
electron gradient called chemiosmosis…occurs
across inner membrane of mitochondria.

Use the space below to describe where each of the 4 steps of cellular respiration
occur – indicate each process on the diagram to the right.
How many ATP, NADP, and FADH2 are
produced during:
Glycolysis?
Intermediate Step?
Krebs cycle?
ETC?
