HOMEOSTASIS STABILITY – KEEP A CONSTANT INTERNAL STATE IN A CHANGING ENVIRONMENT

TO MAINTAIN HOMEOSTASIS, CELLS MUST: - EXCHANGE MATERIALS

- ELIMINATE WASTE

- OBTAIN AND USE ENERGY

- MAKE NEW CELLS

EXCHANGE OF MATERIALS FOR THE CELL CELL MEMBRANES ARE SEMIPERMEABLE – ONLY CERTAIN PARTICLES CAN MOVE IN OR OUT OF CELL (SELECTIVE)

• PASSIVE TRANSPORT: TRANSPORT OF MATERIALS STRAIGHT THROUGH THE CELL MEMBRANE (DOES NOT USE ENERGY)

• ACTIVE TRANSPORT: TRANSPORT OF MATERIALS THROUGH PROTEIN CHANNELS IN CELL MEMBRANE (REQUIRES ENERGY)

DIFFUSION AND OSMOSIS (PASSIVE TRANSPORT)

DIFFUSION • MOVEMENT OF MOLECULES FROM

HIGH CONCENTRATION TO LOW CONCENTRATION

OSMOSIS • MOVEMENT OF WATER THROUGH A

SEMIPERMEABLE MEMBRANE FROM AREAS OF HIGHER TO LOWER CONCENTRATION

DIFFUSION AND OSMOSIS CONCENTRATION GRADIENT: UNEVEN DISTRIBUTION OF A SUBSTANCE ACROSS A BORDER

SOLUTE: PARTICLES DISSOLVED IN WATER

SOLUTION: MIXTURE OF WATER AND SOLUTE

• ISOTONIC: EQUILIBRIUM, SAME CONCENTRATION IN 2 DIFFERENT AREAS

• HYPERTONIC: THE AREA WITH HIGHER CONCENTRATION OF SOLUTE (LESS WATER)

• HYPOTONIC: THE AREA WITH LOWER CONCENTRATION OF SOLUTE (MORE WATER)
