Cell Transport

Front

What is the role of proteins in cell transport?

Back

Proteins help large molecules cross the cell membrane, facilitating transport.

Front

How does the cell membrane maintain homeostasis?

Back

The cell membrane controls the movement of substances in and out of the cell.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across the cell membrane from high to low concentration without the use of energy.

Front

What is active transport?

Back

Active transport is the movement of molecules across the cell membrane from low to high concentration, requiring energy.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses proteins to help move molecules across the cell membrane.

Front

What is the difference between facilitated diffusion and protein pumps?

Back

Facilitated diffusion does not require energy, while protein pumps do require energy.

Front

What is the function of the cell membrane?

Back

The cell membrane acts as a barrier that controls what enters and exits the cell.

Front

What are phospholipids?

Back

Phospholipids are molecules that make up the cell membrane, consisting of a hydrophilic head and hydrophobic tails.

Front

What is homeostasis?

Back

Homeostasis is the process by which cells maintain a stable internal environment.

Front

What is concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.
