Active vs Passive Transport

What is PASSIVE TRANSPORT?

• A type of transport that requires energy

• A type of transport that requires carrier proteins

• A type of transport that does not require energy

• A type of transport that does not require DNA

What is ACTIVE TRANSPORT?

• The same thing as passive transport

• A type of transport that requires energy

• A type of transport that requires oxygen

• A type of transport that does not require a cell membrane

What is a concentration gradient?

• A region of space where the amount of something changes

• A region of space where the amount of something is constant

• A region of empty space

• The space outside the cell membrane
