HB Transport and Membrane

Front

What is the hydrophilic portion of the cell membrane?

Back

The hydrophilic portion of the cell membrane refers to the part that is attracted to water, typically the phosphate heads of phospholipids.

Front

What macromolecule is embedded in the lipid bilayer and helps transport molecules?

Back

Protein

Front

What is phagocytosis?

Back

Phagocytosis is a type of endocytosis where a cell engulfs a food particle.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy.

Front

Identify a glycolipid.

Back

A glycolipid is a lipid with a carbohydrate attached, found in the cell membrane.

Front

What is the role of proteins in the cell membrane?

Back

Proteins in the cell membrane help transport molecules, act as receptors, and provide structural support.

Front

What is the lipid bilayer?

Back

The lipid bilayer is a double layer of phospholipids that makes up the cell membrane.

Front

What is the difference between endocytosis and exocytosis?

Back

Endocytosis is the process of taking substances into the cell, while exocytosis is the process of expelling substances from the cell.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain molecules to pass through while blocking others.
