| Question | Answer |
|---|---|
| What process is defined as the movement of particles through proteins from low to high concentration using energy; "uphill movement"? | Active Transport |
| What process is defined as the process used to remove very large particles from a cell? | Exocytosis |
| What process is defined as the partial breakdown of sugars to make ATP in the absence of oxygen; small amounts of ATP are produced? | Fermentation |
| What process is defined as the process of producing ATP using oxygen and glucose; water and carbon dioxide are by-products; large amounts of ATP produced? | Cell Respiration |
| What process is defined as the process where plants capture light energy and convert it into glucose; oxygen is a by-product? | Photosynthesis |
| What process is defined as the diffusion of water across a cell membrane? | Osmosis |
| What process is defined as the diffusion of particles through proteins in the cell membrane from high to low concentration; "downhill movement"? | Passive Transport |
| What process is defined as the movement of particles from high to low concentration; does not require a cell membrane? | Diffusion |
| What process is defined as the cell membrane surrounds a large particle, encloses it in a vesicle, and brings it inside a cell? | Endocytosis |
| The exchange of materials between the cell and its environment occurs across the _______ ____. | cell membrane |
| Diffusion can occur in living and ______ environments. | nonliving |
| Cells like RBCs will _______ if they soak in salty water. | shrink |
| Cells like RBCs will ______ if they soak in pure water like distilled water. | swell |
| Active transport DOES require _______ to occur. | energy |
| The _______ __________ can be described as a phospholipid bilayer. | cell membrane |
| Many small molecules like water and ______ can diffuse directly through the cell membrane because they are so small | oxygen |
| It is natural for particles to flow from ________ to ________ concentration. | high to low |
| Sugar and ___________ _____________ are too big to pass directly through the cell membrane and they must have a protein "doorway." | amino acids |
| Passive transport is the diffusion of particles through proteins from _________ to ___________ concentration through proteins without the use of energy. | high to low |
| What is the abbreviation for cellular energy? | ATP |
| Active transport is the diffusion of particles through proteins from _________ to ___________ concentration through proteins WITH the use of energy. | low to high |
| Diffusion and passive transport do NOT utilize _________. | energy |
| Cell membranes are composed of a _______________ bilayer. | phospholipid |
| Why can oxygen, carbon dioxide and water pass so easily through the cell membrane? | They are very small molecules. |
| Why do amino acids and sugars need a special protein carrier to get through the cell membrane? | They are large molecules and they are repelled by the cell membrane. |
| _________ is a green pigment found in chloroplasts that is used in photosynthesis to convert UV light into glucose. | Chlorophyll |
| Name the two ways that living organisms break down food molecules (glucose) for energy. | cell respiration and fermentation |
| Cell respiration uses __________ gas. | oxygen |
| ____________ does NOT use oxygen gas to break down glucose to make ATP. | Fermentation |
| Cell respiration makes more ___________ than fermentation. | ATP |
| Name the two types of fermentation. | yeast fermentation & lactic acid fermentation |
| Yeast fermentation is the process by which yeast and some types of bacteria convert sugar into ____________ and _______ _____________ gas. | alcohol and carbon dioxide |
| Name two examples of yeast fermentation. | bread rising and producing alcohol |
| Name two examples of lactic acid fermentation. | making yogurt and in animal muscle cells following strenuous |
| Name the products of yeast fermentation. | alcohol, carbon dioxide gas, and small amounts of ATP |
| Name the products of lactic acid fermentation. | lactic acid and small amounts of ATP |
| In what organelle does cell respiration occur? | mitochondria |
| In what organelle does photosynthesis occur? | chloroplast |
