| Question | Answer |
|---|---|
| major types of cells | prokaroyte and eukaroyote. |
| what are the differences between pro. and eukaroyote? | euk. are bigger and have a nucleus |
| what is the function of a plasma membrane | A semi-permeable phospholipid bi layer barrier that separates theinside of the cellular environment from the outside. |
| function of the nucleus | Where DNA resides. DNA is transcribed in the nucleus. |
| function of ribosome | Where mRNA is translated into a polypeptide chain. |
| function of rough ER | Where a polypeptide is manipulated into a 3d shape |
| smooth ER | Site of lipid synthesis, drug and alcohol detoxification |
| Golgi Body | Site where a protein get a chemical tag marking the protein’s finaldestination. |
| mitochondria | site of cellular respiration |
| lysozome | Holds digestive enzymes for breaking material down such as foreignbodies, food particles, damaged organelles. |
| cytoskeleton | Fibrous proteins that give the cell shape/support and assist in cellularand organelle movement. |
| where is ATP created? | mitochondria |
| what is created during cellular respiration | Glucose and oxygen are converted into heat and ATP. |
| 3 steps of cellular respiration | 1.Glycolsis2. Citric Acid Cycle3.OxidativePhosphorylation |
| Forevery molecule of glucose that goes into cellular respiration, how many moleculesof ATP are created at each step? | Glycolysis occurs in the cytoplasm and yields 2 moleculesof ATP;CAC and OP occur in the mitochondria and yield 2 and 36 molecules ofATP, respectively. |
| what is a somatic cell;gamate; how many chromosomes | s= body cell46 ; g= egg and sperm23 |
