|
What are the key features of cellular architecture? |
Microtubules. Microfilaments. Intermediate filaments. |
|
|
What is the structure and function of mitochondria? |
Aerobic respiration + ATP production. Inner membrane (cristae) = oxidative phosphorylation. Matrix = krebs etc. Outer membrane = maintains proton gradient. |
|
|
What is the structure and function of peroxisomes? |
Lipid metabolism and chemical detoxification. Crystalline core. Enzymes that convert hydrogen peroxide to water - needs oxygen. Lipid bilayer membrane. |
|
|
What is the structure and function of endosomes? |
Membrane bound vesicles found in cytoplasm. Basic mechanism of endocytosis. |
|
|
What is the structure and function of lysosomes? |
Membrane enclosed bag of digestive enzymes. Breaks down larrge molecules and old cell parts into components that are recycled. |
|
|
What is the structure and function of the nucleus? |
Contains cells genetic material (DNA). Nucleolus forms RNA subunits. Controls cell activity. |
|
|
What is the structure and function of the endoplasmic reticulum? |
Smooth: put together lipids and important in making new membrane. Rough: glycosylation; helps fold and modify proteins; products shipped to golgi. Has ribosomes. |
|
|
What is the structure and function of the Golgi body? |
Retrieves proteins and other new materials from the endoplasmic reticulum, package them in vesicles and distribute them. = FINAL MODIFICATION |
|
|
What is the structure and function of cytoplasm? |
Liquid that fills the cell. Contains many proteins and dissolved ions required in many cell reactions. |
