    Involved in removing waste from the cell

    Exocytosis

  • 64

    What are the principal components of the plasma membrane

    Lipids (phospholipids and cholesterol), Protein and carbohtdrates

  • 65

    molecules, such as hydrocarbons, can dissolve in the lipid bilayer and pass through the membrane rapidly.

    Hydrophobic (nonpolar) molecules

  • 66

    such as sugars, do not cross the membrane easily.

    Hydrophilic (nonpolar) molecule

  • 67

    As temperature cool, membrane switch from

    fluid state to solid state

  • 68

    The principal components of the plasma membrane

    Lipids, (phospholipids and cholesterol) Protein and carbohtdrates

  • 69

    The plasma membrane has its ability to transmit signal via

    Complex Protein

  • 70

    What are the 2 Protein

    Recpetors and marker

  • 71

    which work as receivers of extracellular inputs and as activator of intracellular processes

    Receptors

  • 72

    which allows cell to recognize each other

    Markers

  • 73

    Key Takes of the Permeability of the Lipid Bilayer

    Hydrophobic (non polar) molecules Hydrophilic (Polar) molecules

  • 74

    such as hydrocarbons, can dissolve in the lipid bilayer and pass through the membrane rapidly

    Hydrophobic (Non polar) molecule

  • 75

    such as sugar, do not Cross the membrane easily

    Hydrophilic (Polar) molecules

  • 76

    Assist with the movement of large molecules like glucose

    Facilitated Transport (also known as Facilitated Diffusion or Passive-Mediated Transport)

  • 77

    The process of moving substance againts their concentration Gradient

    Active Transport

  • 78

    requires the use of chemical energy to move substance across a membrane, againts a confetration Gradient.

    Active Transport

  • 79

    energy from the hydrolysis of ATP is used to move ions into or out of cells against their concentration gradients. The sodium-potassium pump is an important example.

    Primary active Transport

  • 80

    couples the passive movement of one substance with its concentration gradient to the movement of another substance against its concentration gradient. Energy from ATP is used indirectly to establish the concentration gradient that results in the movement of the first substance

    Secondary Active Transport
