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 |
