biochem process

• PASSIVE TRANSPORT

  • high > low concentration
  • WITH concentration gradient
  • known as DOWNHILL TRANSPORT
  • no energy required
• ACTIVE TRANSPORT

  • low > high concentration
  • AGAINST concentration gradient
  • known as UPHILL TRANSPORT
  • requires energy / ATP
• DIALYSIS

  • A process of separating molecules in solution by the difference in their rates of diffusion through a semipermeable membrane
• DIFFUSION

  • It is the movement of a substance from an area of high concentration to an area of low concentration.
• LOWERING SURFACE TENSION

  • done by SURFACTANT
  • lower SURFACE TENSION or INTERFACIAL TENSION
  • liquid - liquid, gas & liquid, liquid - solid ; ASIDE FROM SALT
  • BILE - absorb fats by emulsification
