| Term | Definition |
|---|
| Volume | determines the amount of chemical activity it carries out per unit of time |
| surface area | determines the amount of substances the cell can take in from the outside environment and the amount of waste products it can release to the environment |
| plasma membrane | composed of phospholipid bilayer, hydrophillic "head" of the lipid facing the auqesous interior and extracellular environment, allows the cell to maintian a constant interior environment, selectivity permeable barrier, communicates with cells and recieving signals from the environment, bind and adhering to cells |
| prokaryotic cells | plasma membrane, nucleoid, cytoplasm, cytosol, ribosomes |
| cell walls | located outside the membrane contaains peptidoglycan (polymer of amino sugars linked by covalent bonds) |
| cell fractionation | organelles of cells can be separated from one another after the cells are broken open and centrifuged |
| nucleus | site of DNA replication, site of genetic control, nucelolus assembles riboomes |
| Ticket | short sequence of amino acids that is part of proteins |
| chromatin | DNA combines with proteins to form a fibrous complex |
| ribosomes | found in the RER and inside mitochondria and chloroplasts |
| RER | segregates certain synthesized proteins away from the cytoplasm and transports them, proteins are chemically modified |
| Cytosol | external region of the ER |
| SER | chemically modifying small molecules, site for hydrolysis of glycogen, synthesis of lipids and steroids |
| golgi apparatus | recieves proteins from ER, concentrates, packages and sorts proteins, some polysaccharides are synthesized |
| CIS region | bottom |
| TRANS region | top |
| MEDIAL region | middle |
| lysosomes | contain digestive enzymes, where macromolecules, hydrolyzed to their monomers |
| phagocytsis | eat cellular materials get into the cell |
| autophagy | cell digests its own material |
| mitochondria | convert potential chemical energy, ATP |
| Choloroplasts | contain green pigment are sites of photosynthesis |
