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!!!!

STAGE 3

Kreb’s Cycle takes place in the Matrix (space )of the

Mitochondria

Electron Transport Chain takes place in the INNER MEMBRANE
