Active Transport

Active transport is the movement of large materials across a cell membrane from ______ to ______ concentration

• high to low

• low to high

• high to high

• low to low

Active transport across a cell membrane from low to high concentration, requires

• energy (ATP)

• no energy

• water

• oxygen

A type membrane protein that can pump one substance in one direction, while transporting another substance in the opposite direction.

• pump transport

• bulk transport

• diffusion

• osmosis

Large particles (or large quantities of smaller particles) are moved across the cell membrane with the use of energy.

• pump transport

• osmosis

• bulk transport

• CO₂ + O₂ Transport

A general term for the various types of active transport that move particles into a cell by enclosing them in a vesicle made out of plasma membrane.

• Endocytosis

• Exocytosis

• Osmosis

• Diffusion

A form of bulk transport in which materials are transported from the inside to the outside of the cell in membrane-bound vesicles that fuse with the plasma membrane.
