LO: SWBAB describe the difference between aerobic and anaerobic cellular respiration.

DN: Explain how plants regulate water loss

HW: page 238-239 # 14-16, 21, 22

Cellular Respiration

C6H12O6 + O2 CO2 + H2O + ATP

Releases CO2 by breaking down glucose molecules in the presence of O2Energy in food molecules is used to produce ATP- energy the body can useIt is an enzyme controlled reaction

Where does cellular Respiration occur?

MITOCHONDRIA

Two types of cellular respiration

Aerobic and anaerobic

Oxygen No oxygen

Aerobic Respiration• Used O2 and glucose

Raw materials= O2 and C6H12O6End products= CO2, H2O and ATP

How do these material get into and out of cells?

O2: breathe in, diffused into blood and

carried to cells

C6H123O6: food we consume, diffused into blood and

carried to cells

What is the chemical equation for aerobic respiration?

Do plants carry out aerobic respiration?

YES!!!!

Why do ALL living things carry out cellular respiration?

To carry out life processes: metabolism

Anaerobic Cellular Respiration• Organisms make ATP (energy) without

oxygen• This process is also called anaerobic• There are two types of anaerobic

respiration– Alcoholic fermentation – Lactic Acid Fermentation

Alcoholic Fermentation• Glucose= 2ATP + 2CO2 + alcohol• Yeast and bacteria

Why does bread have so many holes?The gas that is released during

fermentation creates bubbles and pockets that make bread rise

Lactic Acid Fermentation

• Glucose = 2 ATP + lactic acid

• Bacteria and animal muscle cells when they run out of O2

Alcoholic vs Lactic Acid Fermentation

1. What is the organic compound used by both?

2. What is their main product?3. How are they different?

1. Alcoholic fermentation produces2. Lactic Acid fermentation produces

4. What organisms utilize alcoholic fermentation?

5. What organisms utilize lactic acid fermentation?

How are these things made?
