| Term | Definition |
|---|---|
| classification | Domain Kingdom Phylum Class Order Family Genus Species Subspecies Eukarya Anamalia Chordata Mammalia Primate Hominidae Homo Homo Sapien Homo Sapien Sapiens |
| Prokaryote | : uni cellular small and simple > Cell wall, Cell membrane, Protoplasm (aq part called cytosol, ribomes, nucleiod flagella (NA to all) |
| Eukaryotes 1 | Fluid mosaic structure helps w function. Lipid bilayer heads (hydrophilic, polar) facing out and in hydrophilic environments, tails (nonpolar/hydrophobic) touching. Composed of glycolipids, glycoproteins, phospholipids and proteins. Proteins plus o |
| Eukaryotes 2 | Proteins plus other molecules studded and embedded within membrane, help w task of moving stuff in and out since only material w easy access in and out is water and gases. Three classes of membrane proteins available (not easily removed but move free |
| Eukaryotes 3 | Integral proteins Not easily removed but float freely embedded and mostly span entire memb, therefore have influence within and outside cell |
| Eukaryotes 4 | Peripheral proteins and Less mobile and attached to outside of the cell also easily removed |
| Eukaryotes 5 | Lipid bound proteins. Entirely embedded within memb, no portions reaching into or out of cell |
| Eukaryotes 6 | Diffusion passive movement of molecule Change in molecule conc along conc. gradient. Movement generally from area of high conc. to area of low conc. until equi. Size of molecule, temp, conc gradient, state of solute (gas>liquid>solid) diffusion rate |
| Eukaryotes 7 | Osmosis passive movement of water M across memb from hypotonic (High conc ) to hypertonic (low conc ). Isotonic = no net m of water since 0 osmotic pressure. Osmotic pressure function of how conc. of solute. |
| Eukaryotes 8 | Facilitates transport passive m of molecules relying on transport systems in/ out cell. Proteins in memb act as transporters; channel proteins, carrier proteins} passive transport proteins. Resp for m of ions, small polar molecules |
| Eukaryotes 9 | Active transport ATP facilitated movement From low to high conc (unnatural ∴ requires E) by transport proteins. When proteins encounter ATP, they change conformation so that they bind specific ions like Na, K, Ca And H and carry them in/out cell. |
| Eukaryotes 10 Bulk transport m of macro/ large quantity across cell memb | • Endocytosis ingestion of large quantity into – cell engulfs aq. Soln outside cell and memb fold into cell leading to special formation of vesicle known as Endosome. |
| Eukaryotes 11 Bulk transport m of macro/ large quantity across cell memb | Phagocytosis (NA all cells, only by amoebas, neutrophils and macrophages) – ingestion of large molecules e.g bacterial cells - cell engulfs molecule outside cell and memb fold into cell leading to special formation of vesicle known as phagosomes. |
| Eukaryotes 12 Transport of liquid | Pinocytosis all cells- cell drinking |
| Eukaryotes 13: Exocytosis | - reverse of endo excretion system into ECF |
| Eukaryotes 14 : Cytoskeleton & Cytosol | provide structure to cell. Protein filament scaffolding to organize cell for activity plus m of organelles. Made of actin, microtubules and intermediate filaments. |
| Eukaryotes 15 : Actin | AKA microfilaments, thinnest of all cytoskeleton fibers ∴confers flexibilty. Acts to provide support & structure, also in muscle contraction, cell motility and division |
| Eukaryotes 16 : Microtubules A | thickest of protein filaments, therfore confers rigidity that actin filaments. long cylindrical, hollow structures composed of columns of tubulin. located near nucleus, accumulate around the centrosome, |
| Eukaryotes 16 : Microtubules B | provide tracks along which organelles can travel from center to outwards of cell, involved in chromosome movement during cell division |
| Eukaryotes 17 : intermediate filaments | intermediate thickness, fibrous proteins supercolied into cable like structures. NA in all EU cells. Form a network called Nuclear lamina that surround nucleus of cells, also extend through cell 4 stability. |
| Eukaryotes 18 : Cytosol | 50% of cell vol, semifluid. Site of protein Synthesis & location of centrosomes & centrioles, imp parts of cell division |
| Eukaryotes 19: Nucleus | Nucleolus: site of Ribosome synthesis |
