Homeostasis
| Term | Definition |
|---|---|
| Sensor | Detecting the change (Stimulus) (as related to Feedback Loops) |
| Integrator/Control Center | Determines what to do about the change (as related to Feedback loops) |
| Effector | Brings variable back to set point (as related to feedback loops) |
| Feedback | Stimulatory or inhibitory (as related to Feedback loops) |
| Latency | How fast a feedback loop responds |
| Gain | How strongly the feedback is corrected |
| Positive Feedback Loop | i.e. Childbirth and Blood Clotting are accelerated changes to the intial change that activated the system. |
| Negative Feedback Loop | i.e. |
| Matter | Has Mass and takes up space (Chemistry) |
| Elements | Building blocks of Matter (Chemistry) |
| Atom | Units of Elements (smallest unit in the element) (Chemistry) |
| Proton | Positively charged part of the atom and its nucleus (Chemistry) |
| Neutron | NO charge and in the nucleus (Chemistry) |
| Electron | Negatively charged part of the atom, that is ORBITING around the nucleus (Chemistry) |
| Ion | A charged particle (Chemistry) |
| Anion | Negatively charged particle (Chemistry) |
| Cation | Positively charged particle (Chemistry) |
| Molecule | Smallest group/Unit of Atoms bonded together. Can be the same or different elements. (Chemistry) |
| Compound | Specific atoms bonded together in a fixed ratio. |
| Organic Compound | Contains Carbon as the base. Vital for living organisms to properly function. Lots of Carbon-Hydrogen Bonds (i.e. Carbohydrates, Proteins, Amino Acids, Lipids, Triglyceride, Nuclear Acids, DNA (C,H,O,N,P) |
| Inorganic Compound | Does not contain Carbon as the base. (i.e. Acids~HCL, Bases~NaOH, Salt~NaCL, Oxides~Fe203 (Chemistry) |
| Ionic Bond | Transfer of electrons, formation of ions (Chemistry) |
| Covalent Bond | Sharing of electrons, causing stable molecules (i.e. water, glucose, proteins. (Chemistry) |
| Polar | Covalent Bond Subtype ~ unequal sharing of electrons. creates partial charges between atoms (Chemistry) |
| Non-polar | Covalent Bond Subtype ~ equal sharing of electrons. no charge overall (Chemistry) |
| Anabolic | Building more complex molecules. (Chemistry) |
| Catabolic | Breaking complex molecules into more simpler ones (Chemistry) |
| Catalysts | Assist reactions (typically an enzyme (Chemistry) |
