| Term | Definition |
|---|---|
| polypeptide | a linear organic polymer consisting of a large number of amino acids residues bonded together in a chain, forming part of or the whole of a protein molecule |
| carbonhydrate | Carbohydrates, or carbs, are sugar molecules. Along with proteins and fats, carbohydrates are one of three main nutrients found in foods and drinks |
| macromolecule | chemistry. macromolecule, any very large molecule, usually with a diameter ranging from about 100 to 10,000 angstroms 10−5 to 10−3 mm. |
| osmosis | a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. |
| isotonic | taking place with normal contraction. |
| exocytosis | a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane. |
| golgi apparatus | a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport. |
| hypertonic | having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid |
| hypotonic | having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. |
| chromatin | the material of which the chromosomes of organisms other than bacteria eukaryotes are composed. It consists of protein, RNA, and DNA. |
| atp | Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. |
| chemical bonds | a connection between two surfaces or objects that have been joined together, especially by means of an adhesive substance, heat, or pressure. |
| aerobic | relating to, involving, or requiring free oxygen. |
| anaerobic | relating to, involving, or requiring an absence of free oxygen |
| kreb's cycle | The Krebs cycle is used by organisms that respire (as opposed to organisms that ferment) to generate energy, either by anaerobic respiration or aerobic respiration |
| interphase | the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis. |
| ADP | a molecule that is involved in transferring and providing cells with energy |
| centrioles | a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division. |
