| Question | Answer |
|---|---|
| What is The movement of substances across a cell membrane WITHOUT any input of energy from the cell? | Passive Transport |
| What is the simplest type of passive transport where molecules move from an area of higher concentration to an area of lower concentration and are driven by kinetic energy? | Diffusion |
| What is when the concentration of the molecules of a substance are the same throughout a space ? | Equilibrium |
| What is when water molecules diffuse across a cell membrane from an area of higher concentration of H2O to an area of lower concentration ? | Osmosis |
| What is the concentration of solute molecules outside the cell is lower than the inside of the cell and water moves into the cell ? | Hypotonic |
| What is when the concentration of solute molecules outside the cell is higher than the inside of the cell and water moves out of the cell ? | Hypertonic |
| What is when the concentrations of solutes outside and inside the cell are equal and no movement of water occurs ? | Isotonic |
| What is when cells shrink away from cell walls ? | Plasmolysis |
| What is the pressure of water against the cell wall ? | Turgor pressure |
| What is the movement of molecules across a cell membrane through the use of carrier proteins ? | Facilitated Diffusion |
| What is the movement of materials across a cell membrane that requires a cell to expend energy? | Active Transport |
| What moves substances up their concentration gradient? | Cell Membrane Pumps |
| What is a special protein that transports Na+ ions and K+ up their concentration gradients? | Sodium-Potassium Pump |
| What is it called when cells ingest external fluid, macromolecules, and large particles (including other cells)? | Endocytosis |
| What involves the transport of solutes or fluids? | Pinocytosis |
| What involves the movement of large particles or whole cells? | Phagocytosis |
| What is it called when vesicles in the cytoplasm fuse with the cell membrane and release their contents out of the cell? | Exocytosis |
| What takes place from high concentration to an area of low concentration? | diffusion |
| What is the simplest type of passive transport? | diffusion |
| What is a process in which substances move down their concentration gradient across the cell membrane with the assitance of a coarrier protein? | Facilitated Diffusion |
| Do molecules diffuse rapidly or slowly through the facilitated diffusion process? | Slowly |
| T or F: Facilitated diffusion can assist substances to move either into or out of a cell. | True |
| The transport of what substance is a good example of faciltated diffusion? | Glucose |
| What is required in facilitated diffusion process? | Carrier Protein |
| Provides small passageways for ions to diffuse across the lipid bilayer WITHOUT assistance | Ion Channel |
| A carrier protein that represents active transports in animal cells that pumps potasisium (K) into the cell | Sodium-Potassium Pump |
| What manufactures their own food from inorganic substances? | Autotrophs |
| Autotrophes use __________________ to convert light energy from the sun into chemical energy | Photosynthesis |
| The ultimate source of energy for living things come from the _________. | Sun |
| What cannot manufacture their own food? | Heterotrophs |
| How do heterotrophs obtain food? | Hetertrophs obtain food by eating autotrophs or other heterotrophs |
| What involves a complex series of chemical reactions in which the product of one reaction is consumed in the next reaction? | Photosynthesis |
| What is a byproduct of photosythesis? | O2 |
| What travels in waves? | Light |
| The distance from the crest of one wave to the crest of another wave is called a _______________________ | Wavelength |
| What compounds are responsible for absorbing light? | Chloroplast Pigments |
| What absorbs more red light? | Chlorophyll a |
| What absorbs more blue light? | chlorophyll b |
| What absorbs more green light | Carotenoids |
| Where are chlorophylls abundant? | In the leaves of a plant |
| In the fall, plants lose their chlorophylls and their leaves take on the color of the _________________________. | Carotenoids |
| What is the synthesis of ATP? | Chemiosmosis |
| A plant's environment affects what? | The rate of photosyntesis |
| What is the most important factor in the rate of photosynthesis? | Light Intensity |
| When there is a higher light intensity what happens to more electrons? | They become excited |
| CO2 affects the rate of ___________________ | Photosynthesis |
| Temperature affects the rate of ____________________ | Photosynthesis |
| Why would plant cells have both a chloroplast AND mitochondria? | Sugars are made in chloroplasts AND stored and broken down by mitochondria to make ATP |
| Cellular respiration begins with a biochemical pahtway called | Glycolysis |
| What is the main energy currency of cells? | ATP |
| The complex process in which cells make ATP by breaking down organic compounds is called _________ __________. | Cellular Respiration |
| What breaks down food in order to release stored energy? | Cellular Respiration |
| As molecules break down, energy is stored as ATP and what is released? | Heat |
| What begins the process of cellular respiration? | glycolysis |
| What are the 4 main steps to glycolysis? | 1. 6-carbon molecules of glucose is oxidized; 2. glucose is split; 3. molecules of pryuvate are made; 4. ATP molecules are produced |
| What is the net yield of glycolysis? | 2 ATP |
