What is Cellular Respiration?
• Transforms unusable energy
from food molecules into usable
energy for the cell
• Produces ATP
• Uses oxygen
• Occurs in mitochondria
CR inside mitochondria
Glucose + Oxygen
Carbon dioxide + Energy
What cells use cellular
respiration?
• Most cells
What is Fermentation?
• Process to produce energy (ATP) without
the use of oxygen.
• Two types
• Lactic acid fermentation - produces
lactic acid and carbon dioxide
• Alcohol fermentation - produces ethanol

energy to make food
• Requires a pigment
called chlorophyll
• Occurs inside
chloroplasts
