The Cell’s Energy

Photosynthesis Only Plants and some Bacteria (1) Only Plants and some Bacteria Makes sugar using sun’s energy

Happens in chloroplasts by the chemical chlorophyll.

Photosynthesis + + C6H12O6 Glucose O2 Oxygen H2O Water CO2 Carbon Dioxide + Chloroplast

Cellular Respiration Happens in MOST cells (2) Cellular Respiration Happens in MOST cells Cells break down sugar to make ATP Occurs in Mitochondria

Cellular Respiration + + + C6H12O6 Glucose O2 Oxygen Mitochondria H2O Water CO2 Carbon Dioxide + + + ATP

Fermentation Can happen in many cells Makes ATP by breaking down sugar (3) Fermentation Can happen in many cells Makes ATP by breaking down sugar

Not the most efficient way Makes lactic acid or alcohol as a result

Fermentation Mitochondria C6H12O6 Glucose ATP + Lactic Acid OR Alcohol
