1. How do animal cells make energy?
Cellular Respiration
How do animal cells make energy?

2. Science Name for Energy
ATP
Adenosine Triphosphate

3. Cellular Respiration
process by which glucose is broken down by cells in order to obtain cellular energy (ATP)
We get the glucose from food
When Oxygen is used= AEROBIC RESPIRATION
When Oxygen is not used= ANAEROBIC RESPIRATION

4. Equation for Cellular Respiration
C6 H12 O6 + O2CO2 + H2O ATP
Glucose + Oxygen carbon Dioxide water ATP

5. Where Does this Process Happen?
Cytoplasm- Stage 1
Mitochondria- Stage 2 and 3

6. How Do We Generate this Energy?
Three Steps:
Step 1: Glycolysis
Step 2: Kreb Cycle
Step 3: Electron Transfer Chain (Chemiosmosis)

7. Making Energy Happens In Steps

8. STAGE 1 : GLYCOLYSIS: SPLITTING OF GLUCOSE
WHAT?: SEPARATE GLUCOSE INTO TWO PARTS TO EXTRACT SOME ENERGY
OXYGEN IS NOT REQUIRED FOR THIS STAGE
WHERE? CYTOPLASM
RESULTS: 2 PYRUVIC ACID (NOT USABLE)
2 ATP (USABLE)
2 NADH2 (NOT USABLE)

9. Copy and paste this link to view stage one

10. STAGE 2: KREB CYCLE
GOAL: EXTRACT MORE ENERGY PYRUVIC ACID FURTHER BREAKS DOWN
WHERE: MITOCHONDRIA
CONDITIONS: OXYGEN MUST BE PRESENT
RESULTS: 2ATP
4 NADH2 ( UNUSABLE)
1 FADH2 (UNUSABLE)
Note: Organisms that do not use oxygen DO NOT go through stage 2 OR 3

11. STAGE 3: ELECTRON TRANSPORT CHAIN
GOAL: ALL OF NADH2 AND FADH2 ARE CONVERTED TO ATP FINALLY HAVE A LOT OF USABLE ENERGY
36 MOLECULES OF ATP
WHERE: INNER MITOCHONDRIA MEMBRANE
CONDITIONS: OXYGEN IS REQUIRED

12. OVERALL CHEMICAL EQUATION
C6 H12 O6 + O2 6CO2 + 6 H2O ATP
glucose + oxygen carbon dioxide
water
36-38 ATP

13. WHEN OXYGEN IS NOT PRESENT (ANAEROBIC RESPIRATION)
CALLED FERMENTATION
ONLY STAGE 1(GLYCOLYSIS) OCCURS
GET 2 ATP MOLECULES
GLUCOSE2 LACTIC ACID+ 2 CARBON ATP
DIOXIDE Or
Glucose 2 ethanol + 2 carbon dioxide+ 2 ATP
SOME BACTERIA AND YEAST GET ENERGY FROM THIS PROCESS
