Exploring Cell Membrane Transport Mechanisms

Nucleus

Ribosome

Mitochondria

Plasma membrane

Incapable of transporting ions

Contains a bilayer of phospholipids

Composed solely of proteins

Permeable to all substances

Simple diffusion

Secondary active transport

Exocytosis

Primary active transport

Movement of water molecules

Active transport of glucose

Transport of ions through protein channels

Transport of large molecules using vesicles

Transport of glucose against concentration gradient

Active transport of ions

Movement of water through a selectively permeable membrane

Transport of proteins

Provides energy

Facilitates diffusion

Acts as a carrier protein

Forms a gradient

Use of ATP to move solutes against their concentration gradient

Transport of water molecules

Movement of solutes from high to low concentration without energy

Passive movement of ions through channels

Symport moves molecules in the same direction, while antiport moves them in opposite directions

There is no difference; they are the same

Symport requires ATP, while antiport does not

Symport involves water molecules, while antiport involves ions

Release of materials from the cell to the outside environment

Engulfing of large particles by the cell

Movement of water molecules

Transport of ions against their concentration gradient

To digest large particles

To expel waste materials from the cell

To transport specific molecules into the cell via receptors

To create a concentration gradient
