1. What powers a cell? LightPhotosynthesis experiments showed us that Light is used by plants as the energy to synthesize Glucose. And we know ATP the source of energy (the little rechargeable battery) used to by all cells to do work

2. Our guiding question The energy source for nearly all ecosystems is the sun The energy source for nearly all cellular processes is ATP How is energy from the sun transformed and stored in molecules of ATP to be used for cellular work? Sun ATP PPP

3. LIGHT ENERGY CHEMICAL ENERGY Glucose Carbon dioxide PPP PPP ENERGY FOR CELLULAR WORK ATP ADP P+ Matter cycles as energy is transformed

4. LIGHT ENERGY CHEMICAL ENERGY Glucose Carbon dioxide PPP PPP ATP PhotosynthesisCellular respiration Light energy Energy stored in glucose Energy stored in ATP PhotosynthesisCellular respiration Trace how the energy is transformed

5. How is energy from the sun transformed and stored in ATP? Sun ATP PPP Light energy Energy stored in glucose Energy stored in ATP PhotosynthesisCellular respiration

6. The goal: We will learn the inputs and outputs of cellular respiration and where it takes place. Light energy Energy stored in glucose Energy stored in ATP Photosynthesis Cellular respiration

7. Cellular respiration Glucose is broken into carbon dioxide and water to gain energy to build ATP Oxygen is required as an input Most of the process occurs in mitochondria INPUTS Glucose Oxygen (ADP + P) OUTPUTS Carbon dioxide Water ATP
