3.1 Organelles
Cells
| Question | Answer |
|---|---|
| Organelles | internal structures that carry on specific functions |
| Mitochondria: site of | cellular respiration |
| Mitochondria uses.... | organic compounds to make ATP |
| ATP | main energy currency used to power the body (from cellular respiration) |
| Ribosomes | synthesis of proteins |
| mRNA | messenger RNA: carries original code of DNA to ribosome |
| tRNA | transfer RNA: carries an amino acid to a ribosome |
| rRNA | ribosomal RNA: the factory that puts the amino acids together to make a protein |
| Nucleus | brain of cell stores DNA |
| Rough Endoplasmic Reticulum (ER) | Synthesis &/or modification of proteins |
| Golgi Apparatus | processes, packages and secretes molecules/proteins (& lipids) |
| Lysosomes | intracellular digestion |
| Cytoskeleton | structure and shape of cell |
| Cilia and Flagella | movement |
| Vacuole & Vesicle | storage and transport of substances; |
| Centrioles | aids in cell division |
| cytoplasm | contains everything between the cell membrane and the nucleus |
| cytosol | a gelatin like solution surrounding the organelles |
| Nucleolus | RNA & ribosomal proteins are made here & move into the cytoplasm or ER |
| Vacuole & Vesicle examples: | lysosome/peroxisome |
| Lysosomes- digest molecules with | enzymes |
| Smooth Endoplasmic Reticulum (ER) | synthesis of lipids |
