Cellular Respiration

Where does cellular respiration occur?

• In every cell of our body

• Endoplasmic reticulum
• In our blood

• Cell membrane

What is the first step in cellular respiration?

• Photosynthesis
• Krebs cycle
• Electron transport chain

What is the chemical equation for cellular respiration?

• H2O + CO2 -> C6H12O6 + 6O2
• 6CO2 + 6H2O -> C6H12O6 + 6O2
