Energy: Cellular Respiration
MITOCHONDRIA
What is produced from eating food (heterotrophs) or made by plants (autotrophs) that is necessary for cellular respiration?
What is produced from eating food (heterotrophs) or made by plants (autotrophs) that is necessary for
cellular respiration? GLUCOSE
Photosynthesis
Cellular Respiration
Reactants ProductsReactants of one are products of
the other!!!!
What is the equation for Cellular Respiration?
(Hint: Think photosynthesis in reverse)
__________ + ______ → ______ + _____ + ________
What is the equation for Cellular Respiration?
(Hint: Think Photosynthesis in reverse)
Must know this equation!!!!

What type of living things do Glycolysis? STEP #1 of Cellular Respiration
All living things doglycolysis!!!!
Electron Transport Chain
Kreb’s Cycle
NADH

2 ATP
Glycolysis
Glycolysis takes place in the cytoplasm and needs 2ATP to break 1 Glucose→ 2 PGAL’s
NAD+ → NADH (energy carriers)
ADP → ATP(chemical energy)
4 ATP’s are made but 2 ATP’s go back into
Glycolysis Net 2 ATP’s

Anaerobic Fermentation
(Lactic Acid or Alcoholic)
2 Pyruvates
Where does Anaerobic Fermentation take place?
What organisms do alcoholic or lactic acid fermentation?
What is created from fermentation that is needed for Glycolysis to continue making 2 ATP’s?
Where does Anaerobic Fermentation (no oxygen) take place?
Cytoplasm
What organisms do alcoholic or lactic acid fermentation?
Alcoholic = YeastLactic Acid = Animals
(In muscles during short bursts of energy)
What is created from fermentation that is needed for Glycolysis to continue making 2 ATP’s?
2 NAD+
