A&P 2 test part 2
| Question | Answer |
|---|---|
| cell theory | 1. All living things are made up of one or more cells 2. The cell is the basic unit of life 3. All cells come from pre existing cells |
| osmosis | diffusion of water across a selectively premeable membrane high water --> low water |
| Glut 4 | is a glucose transporter protein and helps glucose enter certain cells. |
| diabetes | problems with blood glucose regulation, problems with insulin signaling can interfere with glucose entering cells |
| prokaryotes | single-celled organism that lacks a distinct, membrane-bound nucleus (Bacteria) |
| eukaryotes | organisms whose cells contain a membrane-bound nucleus and other internal structures called organelle (Animals) |
| stages of mitosis | Prophase, Metaphase, Anaphase, Telophase |
| Prophase | chromosomes first come visible |
| Metaphase | Chromosomes line up in the middle of the cell |
| Anaphase | phase of mitosis where sister chromatids separate to opposite poles |
| Telophase | phase of mitosis, the nuclear membrane begins to reappear |
| Tay Sachs Disease | disorder when lysosomes fail to clear waste products from cell, affects the nerve cells |
| How Glut 4 and diabetes are related | If insulin signaling of Glut 4 movement/function doesnt work properly... less glucose enters cells, more glucose remains in the blood, and blood glucose levels increase |
