ADENOSINE TRI-PHOSPHATE
Energy stored in the phosphate bond.
Photosynthesis takes place in chloroplasts
Cellular Respiration takes place in mitochondria
Plant cells have both chloroplasts
and mitochondria!
All other Eukaryotes only have
mitochondria!
What is produced from eating food (heterotrophs) or made by plants (autotrophs) that is necessary for cellular respiration? GLUCOSE
Photosynthesis
Cellular Respiration
Why are Photosynthesis and Cellular Respiration Opposites?
Photosynthesis
Cellular Respiration
Reactants ProductsReactants of one are products of
the other!!!!
What is the equation for Cellular Respiration?
(Hint: Think Photosynthesis in reverse)
Must know this equation!!!!
• Once a cell has glucose, what process takes place to convert the glucose into 2 ATP (energy) and 2 Pyruvates?
Glycolysis• Where does this process take place in the cell?
Cytoplasm
What type of living things do Glycolysis? STEP #1 of Cellular Respiration
AnimalsPlantsProtistsFungiBacteria
All living things doglycolysis!!!!
Most bacteriaonly use glycolysisto make 2 ATP’s anddon’t need more to function because they are so small.

2 ATP
Glycolysis
4 ATP’s are made but 2 ATP’s go back into
Glycolysis Net 2 ATP’s
2 Pyruvates(Pyruvic Acid)
NAD+ → NADH (energy carriers)
ADP → ATP(chemical energy)
Glycolysis takes place in the cytoplasm and needs ATP to break 1 Glucose→ 2 PGAL’s
CYTOPLASMOxygen presentCellularRespiration(aerobic)
Oxygennot presentAnaerobicFermentation
Anaerobic Fermentation
(Lactic Acid or Alcoholic)
2 Pyruvates
Anaerobic Fermentation (no oxygen) takes place in the Cytoplasm
Alcoholic - Yeast Lactic Acid – Animal Muscles
Important Product of Fermentation = 2 NAD+
All Eukaryotes!!!!
GLYCOLYSIS – In Cytoplasm

STAGE 3
Kreb’s Cycle takes place in the Matrix (space )of the
Mitochondria
Electron Transport Chain takes place in the INNER MEMBRANE
