MCAS Energy and Transport Vocab Review

Cell membrane

• process that uses food to make energy for the cell
• process that requires oxygen
• concentration of a solution inside cell is higher so particles move out - cell shrinks
• encloses the cytoplasm in all cells - allows things to enter or leave

Lipid bilayer

• larger particles are moved into the cell using vesicles
• process that uses food to make energy for the cell
• process that requires oxygen
• structure of cell membrane - contains two layers of phsopholipids

Passive transport

• describes the pressure in a plant cell that causes it to shrivel or be rigid
• process that requires oxygen
• concentration of a solution inside cell is lower so particles move in - cell swells
• One of the two main types of transport, does not require energy

Concentration gradient

• water moves from high to low without the use of energy
• large particles are moved out of the cell using vesicles
• scale measuring the amount of a substance across a space
• describes the pressure in a plant cell that causes it to shrivel or be rigid

Equilibrium

• concentration of substances are the same all over
• concentration of a solution inside cell is higher so particles move out - cell shrinks
• structure of cell membrane - contains two layers of phsopholipids
• scale measuring the amount of a substance across a space

Diffusion

• concentration of a solution inside cell is higher so particles move out - cell shrinks
• movement of substances from high to low concentration - no energy is required
• concentration of a solution inside cell is lower so particles move in - cell swells
• concentration of substances are the same all over

Osmosis

• water moves from high to low without the use of energy
• concentration of a solution inside cell is higher so particles move out - cell shrinks
• a lipid with a polar head a nonpolar tail - makes up the cell membrane
• process that takes place after Glycolysis if no oxygen is present

Hypertonic

• concentration of a solution inside cell is higher so particles move out - cell shrinks
• structure of cell membrane - contains two layers of phsopholipids
• One of the two main types of transport, does require energy
• series of steps that convert one substance into another

Hypotonic

• What comes out of a chemical reaction (right hand side)
• allows some things to pass and others not to
• larger particles are moved into the cell using vesicles
• concentration of a solution inside cell is lower so particles move in - cell swells

Isotonic

• concentration of a solution is equal inside and outside - cell stays same
• concentration of a solution inside cell is lower so particles move in - cell swells
• process that takes place after Glycolysis if no oxygen is present
• scale measuring the amount of a substance across a space
