1 Photosynthesis & Cellular Respiration

2 The process by which energy from the sun is used to convert carbon dioxide and water into glucose and oxygen Photosynthesis

3 Photosynthesis Cont Photosynthesis occurs in algae, certain types of prokaryotes, and the chloroplasts of eukaryotic plants Structure and shape of a leaf is adapted for photosynthesis Leaves are flat, only a few cells thick, and expose a large surface area to the sun CO 2 from air enters leaf via adjustable pores, stomata, in epidermis

4 Chemical Equation of Photosynthesis 6CO 2 + 6H 2 O + Energy C 6 H 12 O 6 + 6O 2 (Light)

5 The process by which the stored energy in glucose molecules is broken down to release ATP. Cellular Respiration

6 Chemical Equation of Cellular Respiration C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O + Energy (ATP)

7 Cellular Respiration Cont Cellular respiration occurs in all eukaryotic organisms Begins in the cytoplasm, but is completed in the mitochondria Produces ATP for the cell Remember ATP is the only usable form of energy for the cell

8 Cellular Respiration is NOT: Breathing Exchange of gases with the atmosphere The transport of oxygen and carbon dioxide to/from the cell.

9 Types of Cellular respiration Aerobic Requires oxygen in order to take place This process produces more energy Anaerobic Does not require oxygen to take place Simple process that produces energy quickly

10 Comparing Photosynthesis and Cellular Respiration Photosynthesis Requires energy Uses enzymes Uses ETC Gives off oxygen as waste Requires carbon dioxide and water Occurs in the chloroplast Respiration Requires energy Uses enzymes Uses ETC Requires oxygen to breakdown sugars Gives off carbon dioxide and water as waste Occurs in the cytoplasm and the mitochondria.
