Warm Up #3 4/17. Why do we study “CHNOPS”? Which macromolecule has the most energy (aka “long-term”) energy? Which type of macromolecules are enzymes? What do enzymes do? Which one of these is a macromolecule: nucleic acid or fatty acid?. Agenda 4/17. Photosynthesis Notes Practice

“I can explain how all living things get their energy from the sun”
Autotrophs: Organisms that can make their own food (from sunlight, heat, or chemicals)Examples: plants, algae, some bacteria
Heterotrophs Organisms that consume other organisms to get food are called
KEY CONCEPT: all organisms on earth depend on the sun’s energy to live (either directly or indirectly)
Photosynthesis: Process where organisms use water, carbon dioxide, and energy from the sun to make glucose
(These compartments are surrounded by a liquid called stroma)
Chlorophyll absorbs blue & red light the best, but reflect green light—so plants look green!
A. Carbon dioxide (CO2) enters the leaf through stomata
B. he carbon dioxide and hydrogens from water are turned into glucose using energy stored from the Light Reactions (Step 1)
**Energy stored in glucose can be used by the plant or and animal that eats it!**
