Autotrophs vs Heterotophs Autotrophs make their own food. Heterotrophs get energy from other organisms by eating.

Autotrophs vs Heterotophs Autotrophs make their own food. – Turn light energy into chemical energy Heterotrophs get energy from other organisms by eating. – Eat for chemical energy

Chemical Energy Chemical energy comes from FOOD Organic molecules store energy in their chemical bonds. These bonds must be broken to release energy

Cellular Respiration Cellular Respiration is the process by which food molecules are broken down to release energy

Cellular Respiration: Cellular respiration is a chemical reaction that occurs in the mitochondria O 2 + C 6 H 12 O > CO 2 + H 2 O + ATP

Cellular Respiration: O 2 + C 6 H 12 O > CO 2 + H 2 O + ATP

Cellular Respiration: O 2 + C 6 H 12 O > CO 2 + H 2 O + ATP Oxygen + Organic Molecule >Carbon Dioxide + Water + Energy

ATP When organic food molecules are broken down, energy is released. This energy is captured in special energy molecules called ATP ATP is the energy molecule that powers all cell activities.

ATP ATP is the most important product of cellular respiration

QUESTIONS What is an organic molecule? What are some examples of organic molecules? How do you release energy from an organic molecule?

What is the process called where organic molecules are broken down to release energy?

Explain why a mirror gets foggy when you breath on it.

What is ATP? Why is it important?

Organic Molecules Organic molecules can be broken down to release energy Once broken down, organic molecules can be rearranged to form other organic molecules.

Macromolecules are Organic Molecules Carbohydrates C,H,O – Glucose, simple sugars, Starch Proteins C,H,O,N,S – Enzymes Lipids (Fats) C,H,O,P – Cell membrane Nucleic Acids C,H,O,P,N – DNA
