Study Notes
Endocytosis and Exocytosis
- Endocytosis: The process of taking substances into a cell by engulfing them.
- Exocytosis: The process of releasing substances from a cell.
Prokaryotes vs. Eukaryotes
- Prokaryotes: No nucleus, simple structure (e.g., bacteria).
- Eukaryotes: Have a nucleus, more complex (e.g., plants and animals).
Cellular Respiration and Photosynthesis
Types of Organisms
- Autotrophs: Organisms that make their own energy (e.g., plants).
- Heterotrophs: Organisms that get energy by eating others (e.g., animals).
Electron Carriers
- Electron carriers: Molecules like NADH and FADH₂ that transport energy during respiration.
Photosynthesis Products and Waste
- Photosynthesis Products = Glucose and Oxygen
- Photosynthesis Waste = Water
Energy from the Sun
- Photosynthesis uses sunlight to turn water and carbon dioxide into sugar and oxygen.
Cellular Respiration Steps
- Energy from the sun: Photosynthesis uses sunlight to turn water and carbon dioxide into sugar and oxygen.
- Glycolysis → Krebs Cycle → Electron Transport Chain
Cellular Respiration Products/Waste
- Cellular respiration Products = ATP; waste products = water and carbon dioxide.
Aerobic Respiration
- Aerobic respiration: The first step of respiration, breaking down glucose for energy.
Krebs Cycle
- Krebs Cycle: Produces electron carriers for the electron transport chain.
Electron Transport Chain
- Electron Transport Chain: Uses electrons to make a large amount of ATP.
Lactic Acid Fermentation
- Lactic Acid Fermentation: Energy production in the absence of oxygen.
