Cellular Respiration
Part 1 - Overview

2. THE BIG PICTURE
Past - Photosynthesis converts the Sun’s energy in chemical potential energy of food.
Present – Cellular Respiration converts the chemical potential energy stored in food to the chemical potential energy stored in ATP.
Future – ATP supplies the energy to do cell work.

3. MAIN Idea
Living organisms obtain energy by breaking down GLUCOSE during cellular respiration

4. Overview of Cellular Respiration
The point of cellular respiration is to harvest chemical energy from food (such as Glucose) and store it in the chemical bonds of ATP (which provides energy for cellular work)
The equation for cellular respiration is the opposite of the equation for PHOTOSYNTHESIS.

5. Overview of Cellular Respiration
Cellular respiration occurs in two main parts.

6. 2 Main Part of Cellular Respiration
The first stage, GLYCOLYSIS, is an anaerobic process
Anaerobic processes do not require OXYGEN
The second stage, AEROBIC RESPIRATION, is an aerobic process
Aerobic processes require OXYGEN
This stage includes the Krebs cycle and electron transport
