MT: Chemical Reactions and Cell Processes

2. Levels of Organization of Life
Atoms
Molecules
Organelles
We are now focusing on a microscopic level
Cells
Tissue
Organ
Organ system
Organism

3. Prokaryote A unicellular organism without a nucleus or organelles
Ex: bacteria

4. Eukaryote Organism that has a nucleus and organelles
Ex: plants, animals, fungi, protista

5. Cytoplasm Jelly-like fluid that cell contents float in
In eukaryotes and prokaryotes

6. Semi-permeable Cell Membrane
A phospholipid (fat) bilayer that surrounds cells and regulates what goes in and out of the cell
In prokaryotes and eukaryotes

7. Adenosine Triphosphate (ATP)
A chemical that creates energy when one of its three phosphates is removed
Constantly recycled
ADP + P = ATP

8. Photosynthesis
CO2 + H2O + sunlight = C6H12O O2
A chemical reaction in which CO2, H2O, and sunlight produce O2 and C6H12O6 (glucose)
Producers and some bacteria do this

9. Cellular Respiration
C6H12O O2 = CO2 + H2O + ATP (energy)
A chemical reaction in which O2 and C6H12O6 (glucose) produce CO2, H2O, and ATP (energy)
Plants and animals do this
