Bio EOCT Domain I
Review of EOCT content for cells
| Question | Answer |
|---|---|
| Type of cell that has no nucleus or membrane-bound organelles | prokaryote |
| Kingdoms that have prokaryotic cells | Eubacteria and Archeabacteria |
| Type of cell that contains a nucleus and membrane-bound organelles | eukaryote |
| 4 kingdoms with eukaryotic cells | Protista, Fungi, Plantae, and Animalia |
| parts of the cell that perform a specific function | organelles |
| Function of this cell part is to allow certain substances to pass through it | cell membrane |
| Part of plant cells that gives support and protection | cell wall |
| organelle that provides energy for the cell | mitochondrion |
| Organelle that converts sunlight into chemical energy | chloroplast |
| Organelle that breaks down food molecules and makes ATP | mitochondrion |
| Organelle that controls the cell's activities | nucleus |
| Organelle that contains the genetic information of the cell | nucleus |
| Organelle that modifies and packages proteins | Golgi body |
| Organelle that produces proteins | ribosomes |
| Organelle that stores materials like water, food, or wastes | vacuole |
| Internal conditions remain relatively constant even though external conditions change | homeostasis |
| A cell membrane that only allows certain things to pass is said to be this | selectively permeable |
| Any type of cellular transport that moves from high to low concentration and does not require energy | passive transport |
| type of cellular transport that moves from low to high concentration and requires energy | active transport |
| the simplest type of transport that moves from high to low concentration | diffusion |
| movement of water molecules across the cell membrane | osmosis |
| movement of molecules across a cell membrane from high to low concentration but requires a protein molecule | facilitated diffusion |
| movement of molecules with the concentration gradient | diffusion (passive transport) |
| movement against the concentration gradient | active transport |
| movement of large particles into the cell by forming a vacuole | endocytosis |
| movement of large particles out of the cell | exocytosis |
| a biological catalyst that speeds up a reaction | enzyme |
| the substance an enzyme acts upon | substrate |
| The area of an enzyme where the substrate attaches | active site |
| enzymes function by lowering the energy required to get a reaction started called this | activation energy |
| The rate of a reaction will do this if the temperature is raised | It will increase |
| simple sugars belong to this group of organic molecules | carbohydrates |
| glucose, a one sugar molecule, is this type of carbohydrate | monosaccharide |
| many sugars joined together like cellulose in cell walls, is this type of carbohydrate | polysaccharide |
| The function of a carbohydrate | energy |
| common name of a lipid | fats and oils |
| function of a lipid | long term energy storage, make up cell membranes |
| organic molecules that are building blocks of the body including enzymes, muscles, hair, nails. | proteins |
| Organic molecules that store and transmit genetic information | nucleic acids |
| two types of nucleic acids | DNA and RNA |
| the monomer that makes up proteins | amino acids |
| the monomer that makes up nucleic acids | nucleotides |
| type of solution with a high concentration of solutes | hypertonic |
| type of solution with a low concentration of solutes | hypotonic |
| What happens to a cell in a hypertonic solution? | shrinks |
| What happens to a cell in a hypotonic solution? | swells |
| If a cell with 1% solute concentration is placed in a solution with a 3% solute concentration, what will happen to the cell? | shrinks, hypertonic solution |
