  9. Cell membrane
    Biochemical structure surrounding cell that is selectively permeable to various molecules and is involved in variety of cellular processes including cell adhesion, ion channel conductance and cell signaling
  10. Cellular excretion
    Process of removing waste and other non useful products from cell
  11. Cholesterol
    Waxy steroid metabolite that is an essential structural component of cell membranes, where it aids in membrane permeability and fluidity.
  12. Cytoplasm
    All organelle and other materials within the cell excluding the nucleus and nuclear membrane
  13. Diffusion
    Movement of particles across a membrane from an area of higher concentration to an area of lower concentration without energy input
  14. Embedded protein
    Protein that is associated with a membrane that usually acts as a carrier protein to aid in the transport of a molecule across the membrane
  15. Cytosol
    Liquid portion of the cytoplasm that is found outside of the organelles
  16. Ensocytosis
    Uptake of molecules by cells where the cell membrane surrounds the molecule then forms a vesicle that is released inside cell
  17. Extracellular fluid
    Fluids or liquids including solutes found outside of cells
  18. Facilitated diffusion
    Movement of molecules through a membrane down a concentrate gradient with the aid of a transmembrane protein channel
  19. Filtration
    Movement of ions across permeable cell membranes from a high concentrate gradient to a low concentrate gradient due to hydrostatic pressure
  20. Glycolipid
    lipid containing carbohydrate group, usually galactose
  21. Glycoprotein
    Proteins that have carbohydrate bound to them
  22. Hepertonic
    Condition where the concentration of impermeable solutes is greater inside the cell than the concentration of the impermeable solutes on the other sideof the membrane
  23. Homeostasis
    Regulation of internal environment to maintain a stable, constant condition
  24. Hypotonic
    Condition where the concentration of impermeable solutes is less inside the cell than the concentration of the impermeable solutes on the other side of the membrane
  25. Interstitial fluid
    Fluid found in the intercellular spaces (between cells) including the dissolved solutes
  26. Intracellular fluid
    Fluid or liquid including solutes found inside of cell.
  27. Isotonic
    Condition where the concentration of impermeable solutes is equal on both sides of the membrane
  28. Membrane
    Chemical structures that surrounds organelles, cells or tissues that serve as a selective barrier to specific molecules, or substances, thus controls what enters or leaves the structure.
  29. Nucleus
    Membrane enclosed cellular organelle that contains multiple DNA molecules that controls cell activity by regulating gene expression
  30. Omosis
    Diffusion of water molecules across a membrane in response to differences in solute (usually ions) concentration.
  31. Organelle
    Membrane bound structure excluding the nucleus found inside cell membranes that have specific functions
  32. Passive transport
    Diffusion across a plasma membrane from areas of high concentration to areas of lower concentration where the cell expends no energy
  33. Peripheral protein
    Membrane bound protein that functions as enzymes, communication and cell organization
  34. Permeability
    Property of a material that lets fluids (such as water or water vapor) to diffuse through it to another medium without being chemically or physically affected
  35. Phagocytosis
    Engulfing of solid particles by the cell membrane to form an internal vesicle
  36. Phospholipid
    lipid consisting of a glycerol bound to two fatty acids and a phosphate group.
  37. Pinocytosis
    Method of uptake of small particles and fluids are brought into the cell suspended within small vesicles
  38. Plasma membrane
    Biochemical structure surrounding cell that is selectively permeable to various molecules and is involved in variety of cellular processes including cell adhesion, ion channel conductance and cell signaling
  39. Secondary active transport
    Method of transport where primary molecule uptake does not require energy, but this molecule results in uptake of secondary molecule that requires energy for excretion
  40. Secretion
    Process of segregating, elaborating, and releasing molecules from a cell
  41. Tonicity
    Measure of the osmotic pressure of two solutions separated by a semipermeable membrane
  42. Transmembrane protein
    Cell membrane protein that spans the membrane and is generally used in transportation of molecules through membranes or transporting a message or signal through a membrane
