Other questions in this quiz

2. Define exocytosis

  • the passive movement of molecules across membranes, down their concentration gradient, which is aided by carrier protein molecules.
  • the process of removing materials from the cell by fusing vesicles containing the material with the plasma membrane
  • the process of taking materials into a cell by surrounding them with part of the plasma membrane, which then pinches off to form a vesicle inside the cell.
  • the movement of molecules down a concentration gradient, from an area of high concentration, to an area of low concentration.

3. define division of labour?

  • each type of organelle has a specific role within the cell
  • equal amount of work for each organelle
  • amount of work an organelle does
  • what organelle completes what function

4. what are vesicles?

  • alternative name for nuclear pores
  • membrane-bound sacs found in cells, that are used to carry many different substances around cells.
  • the organelle that is involved in protein synthesis
  • types of blood cell

5. Define Active Transport

  • the movement of molecules against it's concentration gradient, using energy in the form of ATP, and transport proteins
  • the passive movement of molecules across membranes, down their concentration gradient, which is aided by carrier protein molecules.
  • the movement of molecules down a concentration gradient, from an area of high concentration, to an area of low concentration.
  • the movement of water molecules from a region of higher water potential, to a region of lower water potential, across a partially permeable membrane
