| Major groups of biological macromolecules is : | Proteins |
| How many common amino acids? | 20 |
| Amino acids are joined by ____ ? | Peptide Bonds |
| Proteins can be __________. | Structural, Transportation, and Hormones |
| Bio-catalyst are also known as? | Enzymes |
| Enzymes are responsible for? | Metabolic Reactions |
| Suffix -ase is for? | types of enzymes |
| Molecule that "fits" enzymes to bring chemical change is? | Substrate |
| The part where the enzyme binds the substrate is called? | The active site |
| what is crucial for an enzyme to work? | Its shape |
| When does an enzyme change shape? | if temperature, salt, or pH levels change. |
| Optimum pH | pH in which enzyme's activity is at its greatest |
| When an enzyme changes shape it is _______. | denatured |
| In creasing temperatures on an enzyme do what? | increase enzyme activity |
| decreasing temperatures on an enzyme does what? | decreases rate of activity |
| Many organisms use enzymes to destroy ______ before it causes damage. | Hydrogen Peroxide |
| Removal of Hydrogen Peroxide in animals is called? | Catalase |
| Removal of Hydrogen Peroxide in plants is called? | Peroxidase |
| Diffusion | Movements of molecules from high concentrations areas to low concentrations areas. |
| Osmosis | type of diffusion that moves water from high water content to low water content. |
| high water content aka | low solute |
| low water content aka | high solute |
| Tonicity | amount of solute in a solution |
| Isotonic | equal amounts of solute in and out of membrane |
| hypotonic | solution outside membrane is lower than inside (big balls) |
| Hypertonic | Solution inside membrane is larger than inside (shrivel) |
| plasmolysis | movement of water in plants |
| Turger pressure | when plants are hypotonic, water moves inside the cell creating pressure |
| turgid | plant cells in hypotonic solution |
| In plasmolysis the cell membrane pulls away from the cell wall gathering _________________ to the center of the cell. | Chloroplasts |
| Central Vacuole | membrane bound organelle that contains water |
| beet red pigment | betacyamin |
