All energy starts with the sun!
Life on Earth is almost entirely solar-powered with nearly all organisms depending ultimately on food made by photosynthesis, which uses energy from sunlight. This is radiant energy

Photosynthesis
Method of converting sun energy into chemical energy usable by cells
– Photoautotrophs: use light– Chemoautotrophs: use
chemicals(in places where it is too dark)

Photosynthesis
Photosynthesis takes place inside chloroplasts in plant
leaves
Chlorophyll (pigment) in chloroplasts gives green color

Energy conversion Photosynthesis
This takes the radiant energy of the sun and converts it to chemical energy stored in the plants as carbohydrates (glucose)

Cellular Respiration
Transformation of chemical energy in food into chemical energy cells can use: ATP
Overall Reaction:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
Sugar + oxygen ---> carbon + water + energy
dioxide

2 kinds of Cellular Respiration
– Anaerobic (no oxygen)
cellular respiration (aka fermentation)
Yields 2 ATPs– Aerobic (with oxygen) cellular
respiration
Yields 36 ATPs
