1. 2.2 Cellular Energy

2. Warm-up Essential Question What biomolecules contain energy?
How do cells make, move, and use energy?

3. ENERGY! All living things need to energy to survive
Starts from the sun (most of the time)
Plants use that to make sugars (for themselves), everything else eats the plants and steals their sugars, or eats something that ate the plants

4. Photosynthesis – step one
Converting light energy into chemical energy
Reactants: CO2 and H2O
Plants, algae, and a few bacteria
The goal is storage to use that energy later
All this is in the chloroplasts

5. Cellular Respiration – step two
The inverse of photosynthesis
Mitochondria (only in Eukaryotes)
Converts the chemical energy stored in glucose into an energy usable by the cell (ATP)
Plants AND animals

7. ATP- Adenosine Triphosphate
The main energy carrying molecule in living things
Glucose is broken apart, releasing the energy which is then stored in ATP
ATP transports energy around the cell
When it is used, it is broken apart into ADP + P (adenosine diphosphate + phosphate)
The energy had been stored in the chemical bond
The particles are recycled and made back into ATP in the mitochondria

10. Aerobic and anerobic
