Membrane Components
The main component of the cell membrane.
What are phospholipids?
Programmed cell destruction.
Pores that allow water to diffuse through cells.
What are aquaporins?
The molecule that provides energy for active transport to occur.
This is the largest type of cell.
The larger part of a phospholipid.
What are fatty acids/lipids?
What is amphiphilic?
This occurs when the solute cannot move across the membrane, but the solvent can.
When a cell membrane closes around a material in order to take it in.
Balance between an organism and its environment.
Protein and carbohydrate structures that are used to identify specific types of cells.
What are glycoproteins?
The type of cells that contain membrane bound organelles.
What are eukaryotes?
A solution with a higher solute concentration.
What is a hypertonic solution?
The organelle that coordinates endocytosis and exocytosis.
What is the golgi body/apparatus?
What is isotonic?
A lipid that helps add stability to the cell membrane.
What is cholesterol?
The structure that animal cells form to send materials to each other.
When protein channels help materials move across the membrane.
What is facilitated diffusion?
Endocytosis with liquids.
What is pinocytosis?
Molecules used to send messages across short distances in nerve cells.
What are neurotransmitters?
Proteins that target cells have which allow them to receive messages.
What are receptors?
The process by which prokaryotes divide.
This is the direction that all gas and liquid materials tend to move due to diffusion.
What is from high to low concentration?
Passageways used to coordinate your heartbeat.
What are gap junctions?
Structures that plant and algae cells use to send materials to each other.
What are plasmodesmata?
