Chapter 3 Quiz A&P
| Question | Answer |
|---|---|
| Cell Membrane | Consists of phospholipids and embedded proteins. It regulates what enters and leaves the cell. It is selectively permeable. |
| Ribosomes | Tiny molecular machines inside cells that build proteins. |
| Mitochondria | the "powerhouse" of the cell, harvests energy. |
| Rough ER | Transports proteins to golgi. Where ribosomes are located. |
| Nucleolus | Responsible for the production of ribosomes. |
| Nucleus | Directs the activities of a cell. |
| Smooth ER | No ribosomes, for lipid synthesis |
| Golgi Body | Package and delivery of proteins |
| Lysosome | Waste disposal and recycling centers of eukaryotic cells by breaking down macromolecules, old cell parts, and foreign invaders. |
| Cilia | Helps clear airways in the respiratory system. |
| Flagella | Acts like a propeller to push things toward or out. |
| Mitochondrial Disorders | When the mitochondria cannot produce enough ATP. Ex: Leigh Syndrome |
| Lysosomal Storage Disorder | When lysosomes are unable to clear toxic material from cells. Ex: Tay-Sachs |
| PCD (Primary Ciliary Dyskinesia) | Affects the function and structure of cilia. |
| How does the cell membrane relate to diabetes? | In the presence of insulin, Glut4 vesicles fuse with the plasma membrane. Glut4 allows glucose to enter the cell. |
| Tay-Sachs | Symptoms: loss of motor skills, seizures, vision and hearing loss. Treatments: supportive care and symptom management to keep the patient comfortable. |
