1. Cellular Respiration

2. ATP = Adenosine Triphosphate
What is it?
Energy molecule
How store energy?
Energy stored in chemical bonds
Energy is released when ATP is broken into ADP
Why needed?
ATP used for many activities
Muscles, heart, translation, mitosis, active transport, etc…

3. Cellular Respiration Overview
Defined: Creation of ATP from glucose
Exergonic reaction: reaction that releases energy
Who: All life
End Result: ATP

4. Glucose (6 carbon molcule)
Step 1: Glycolysis
Glucose (6 carbon molcule)
ATP
ATP
ATP
ATP
ATP
ATP
What happens? Cell gains 2ATP molecules
How it happens? Glucose (from our food) is broken down
Organisms that need more ATP to survive proceed to step 2….aerobic respiration
Plants, animals, fungi, protista
Organisms that don’t need more ATP to survive proceed to step 2…fermentation
Bacteria

5. Step 2: Depends on the Organism
Step 2: Fermentation
Without oxygen
Molecules needed to restart glycolysis created
2 more ATPs can be created
Lactic acid created (soreness)
Step 2: Aerobic Respiration
In mitochondria
With oxygen present
Oxygen recombines ADP to create 36 more ATP molecules
CO2 waste created

6. Kobe Public Service Announcement: Proper Use of Alcohol

7. Maple Center Counseling Program
The Safe Ride Program is a confidential service to Beverly Hills students. If a teenager feels he/she cannot drive safely, he/she can call (888) for a free ride home. This service is available every Friday and Saturday night from 10:00pm to 2:00am and on Prom Night and New Year’s Eve from 10:00pm to 6:00am.

8. Connection between photosynthesis & respiration
Plants
Create glucose through photosynthesis
Glucose is used to make ATP during cellular respiration
Animals
Animals eat plants to obtain their glucose
Glucose is used to make ATP during cellular respiration
