Summary diffusion/osmosis/cells energy (Chapter 4 text)
Term | Definition |
---|---|
Protein | A macromolecule in living things that is made of chains of amino acids subnuits. |
Carbohydrate | A type of carbon-based molecule in living things. |
Nucleic Acid | One of several carbon-based molecules that carry an organism's genetic code. |
Protein | Control the chemical activity of a cell and support growth and repair. |
Carbohydrates | Include sugars and starches used for energy or as structural materials. |
Composed | made up of, put together in form, ex: all living things are ______ of cells. |
Carbohydrate | molecules contain carbon, hydrogen and oxygen |
Energy | can come by means of food-sun, glucose (sugar), carbohydrates. Helps us to do things. |
Cellular Respiration | A process in which cells use oxygen to release energy stored in sugars. |
Fermentation | A chemical process by which cells release energy from sugar when no oxygen is present. |
Herbicide | Effects, Kills, Damages: like vinegar on plants |
Glucose | A sugar molecule that is a major energy source for most cells, produced by the process of photosynthesis. |
Solvent | The part that dissolves something. |
Solute | The material that is getting dissolved. |
Solution | the outcome of two different items put together |
Sustain | to keep in existence; maintain or prolong, to meet the current needs without compromising the future needs of something. |
Repel | to keep away, stay away. Like lipid tails stay away from water. |
Animal Cells | has mitosis phase and centrioles |
Plant Cells | has mitosis phase but no centriole |
46; 23 | Every human has ___________chromosomes or ______amount of pairs |
Passive | During_____________transport, substances are moved from areas of low concentration to high concentration |
Active | In order for the process of passive transport to occur the cell must supply an energy source called_____________ |
Large; Endocystosis | If particles that are too ________pass easily through the membrane it can enter a cell by a process called __________. |
Exocytosis | Large particles can leave a cell by the process called________. |
Osmosis | The diffusion of water through a membrane |
Cell Membrane | Materials move in and out of a cell by passing through the_________________. It allows some materials to pass but prevents others. |
Water, Waste | A cell only survives if ______________is taken into the cell and _______________ are taken out. |
Thermal Radiation | is the release (diffusion) of heat into the air. Ex: visible light |
Diffusion (mixing) | the constant random motion of molecules from an area of high concentration to low concentration |
Gradient | Is the difference in concentration (cell membrane could be one). During diffusion molecules like to move down the __________. |
Gas, Liquid, and Solid | Diffusion happens in 3 states:______,_______,_______ |
Gas | Diffusion happens the fastest in this state |
Solid | Slowest moving diffusion. Vibrates- doesn't move a lot |
Liquid | The 2nd fastest diffusion |
Temperature | Rate of Diffusion: 1 |
Size of Molecule | Rate of Diffusion: 2 |
Steepness Gradient | Rate of Diffusion: 3 |
ATP | Energy made from glucose and oxygen |
Carbohydrates, Lipids, Protein, Nucleic Acids | 4 types of Large Molecules |
Water | A ________ molecule, consists of two hydrogen atoms and one oxygen atom |
Polar | A water molecule is also a ____________molecule |
Lipids | Fats, Oils, Waxes found in living things. |
Membrane; water | Cell_______are composed of special lipids that have one end that _____water. |
