| Question | Answer |
|---|---|
| Passive transport | Movement of substances through the cell membrane WITHOUT using energy |
| Active transport | -Movement of substances throughout the cell membrane USING energy -needed to move molecules that are to big or to move from lesser to higher |
| Diffusion | Movement of MOLECULES from an high to low |
| Osmosis | Movement of WATER from high to low |
| Isotonic | Water enters and leaves at the same rate because concentration is equal both outside and inside the cell |
| Hypertonic | Greater concentration of water inside the cell so water leaves the cell to create equal concentration |
| Hpotonic | Greater concentration of water outside the cell so water enters the cell to create equal concentration |
| Endocytosis | Part of the cell membrane forms vesicles and brings the particle INTO the cell membrane |
| Exocytosis | Vesicle filled particle moves to cell membrane fuses with it and releases to outside cell |
| Metabolism | All chemical reactions in an ORGANISM |
| Enzymes | Proteins that speed up a chemical reaction without being changed or used up |
| Substrate | Molecule an enzyme attaches to |
| Photosynthesis | -Plants use chlorophyll to absorb sunlight -Light energy is converted into chemical energy by producers...uses enzymes |
| Photosynthesis equation | 6CO2+6H2O+energy--->C6H12O6+6CO2 |
| Cellular respiration | Chemical reactions that break down glucose into simpler substances and release stored energy |
| Cellular Respiriation 2 | a) starts in cytoplasm and then moves into mitochondria b)uses oxygen c)each time a glucose molecule is broken down, energy stored in its bonds is released |
| Cellular Respiration Equation | C6H12O2+6O2--->6CO2+6H2O+energy |
| Fermentation | -breakdown of glucose begins in cytoplasm and does not move into mitochondria -occurs when oxygen is NOT present |
| Waste products | Lactic Acid-formed in muscles after exercise Alcohol and CO2-formed when yeast breaks down glucose |
