Ch 5 Plasma Membrane & Homeostasis GRAD_GJSD_26DE

Has two hydrophobic heads and hydrophilic tail

Is entirely hydrophobic throughout its structure

Has both hydrophilic head and hydrophobic tail

Is entirely hydrophilic on both sides

Helps maintain fluidity across temperature changes

Creates pores for rapid water transport

Directly performs enzyme reactions on proteins

Integral bind carbohydrates; peripheral bind lipids

Integral are only outside; peripheral are only inside

Integral span the membrane; peripheral sit on one side

Static double layer with identical components

Solid lipid wall with no proteins present

Flexible phospholipid bilayer with mixed molecules

Signal triggers a cellular response

Membrane dissolves immediately

Cell stops all transport processes

Molecules move from low to high concentration

Molecules move from high to low concentration

Molecules move only if ATP is supplied

Diffusion of water through a selectively permeable membrane from low concentration to high concentration

Diffusion of water through a selectively permeable membrane from high solute concentration to low solute concentration

Diffusion of water through a selectively permeable membrane from high concentration to low concentration

Increasing external osmotic pressure through added sugars

Using ATP pumps to push out salts

Maintaining water balance by controlling water inside the cell

It shrinks because water leaves the cell

It swells and may burst as water enters

It stays the same because water is balanced

Cell wall swells completely and may burst

Cell Membrane pulls away from the cell wall

Vacuoles and chloroplasts expands and fill with water
