3. INTRODUCTION
 NAME SOME OF THE ORGANELLES OF THE CELL THAT YOU REMEMBER.

4. ENERGY.
 WHY DO YOU BREATH?
 WHY DO WE NEED ENERGY?

5. CELLULAR RESPIRATION.
 • The process of cell catabolism in which cells turn food into usable
energy in the form of ATP. In this process glucose is broken down in the
presence of molecular oxygen into six molecules of carbon dioxide, and much
of the energy released is preserved by turning ADP and free phosphate into
ATP.

6. Cellular respiration
 • The process takes place in the mitochondrion of the cells which is
structurally designed for it.
 • There are two types of cellular respiration namely; aerobic and
unaerobic respiration.
 Aerobic respiration is the process whereby energy is produced in the presence
of oxygen.
 Anaerobic respiration is the process whereby energy is produces in the
absence of oxygen.

7. Aerobic Respiration.
 • Aerobic respiration occurs when glucose is broken down in the presence
of oxygen producing energy in the form of ATP.
 • EQUATION OF AEROBIC RESPIRATION : C6H12O6 + 602=6H20 + 6CO2 + 38
ATP
 • There are 3 stages of aerobic respiration namely glycolysis, the kreb
cycle and oxidative phosphorilation.

8. GLYCOLYSIS
 • It takes place in the cytoplasm of the cell where glucose is broken down
to form pyruvic acid and energy rich hydrogen ions.
 • 4 ATP molecules are also released.
 • The hydrogen molecules are carried out by NAD and form NADH.
