| Question | Answer |
| Which membrane protein is incorrectly matched with its function? | Carrier: allows cells to recognize each other and foreign cells. |
| In what locations can ribosomes be found? | 1. attached to endoplasmic reticulum or nuclear surface 2. free ribosomes |
| list the six steps of receptor-mediated endoctosis. | 1. binding 2. vesicle formation 3. uncoating 4. fusion with endosome 5. recycling of receptors to plasma membrane 6. degradation in lysosomes |
| what are the 3 main functions of the nucleus? | 1. controls cellular structure 2. directs cellular activities 3. produces ribosomes in the nucleoli |
| what are the 4 functions of the lysosomes. | 1. digest substances and transport final products of digestion into cytosol 2. autophagy 3. autolysis 4. accomplish extracellular digestion |
| two sources of cellular energy that can be used to drive active transport | 1. energy obtained from hydrolysis of ATP 2. energ stored in an ionic concentration gradient |
| what are the 3 functions of the cytosol | 1. fluid in which many of rhe cell's metabolic reactions occur 2. maintains shape and general organization of cellular contents 3. cellular movement |
| what are the 2 function of mitochondria | 1. generate ATP through reactions of aerobic cellular respiration 2. play an important early role in apoptosis |
| what are the 3 steps of glucose transport into the cell? | 1. glucose binds to the glucose transporter (GluT) on the outside of the membrane 2. GluT changes shape allowing glucose to pass 3. GluT releases the glucose on the other side of the membrane |
