Term
| A disorder in which organelle results in Hermandky-Pudlow (HP) syndrom? |
|
Definition
|
|
Term
| How do organelle membranes promote the activity of certain enzymes? |
|
Definition
| Organelle membranes allow the area within to maintain a pH separate from the cytosol (which is around 7). This allows enzymes to function at their optimal pH and environment. |

Term
| Name 3 Hallmarks of a Eukaryotic Cell |
|
Definition
1. Membranes comparmentalize functions to increase efficiency
2. Cytoskeleton maintains organization among organelles
3. Cell surfaces recognize, interpret, and allow communication with the environment. Cells also organize into higher communities. |

Definition
1. Microfilaments
2. Intermediate filaments
3. Microtubules |
|
|
Term
| What are microfilaments made of, and what do they allow a cell to do? |
|
Definition
Made out of actin
Allow cells to move and change shape |
|
|
Term
| What role do intermediate filaments play? |
|
Definition
| Mechanical support for cells |
|
|
Term
| What do microtubules allow cells to do? |
|
Definition
1. Allow movement of cilia --> allows movement
2. Allow cells to change shape |
|
|
Term
| Describe the proposed mechanism by which cells inherited mitochondria |
|
Definition
| - Symbiotic uptake of mitochondria by pre-eukaryotic cells (cells provide protection, mitochondria ATP) |
|
|
Term
