Cellular Processes

Front

What is the process called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

Back

Facilitated Diffusion

Front

What is the term for the transport mechanism that requires energy to move substances against their concentration gradient?

Back

Active Transport

Front

What is the process called when large particles are moved out of the cell?

Back

Exocytosis

Front

What is the main difference between passive transport and active transport?

Back

Passive Transport does NOT require energy, while Active Transport DOES require energy.

Front

What is the movement of water from an area of higher concentration to an area of lower concentration called?

Back

Osmosis

Front

What type of transport does NOT require energy and occurs along the concentration gradient?

Back

Passive Transport

Front

What is the role of carrier proteins in facilitated diffusion?

Back

Carrier proteins help transport molecules across the cell membrane without using energy.

Front

What is the significance of ATP in active transport?

Back

ATP provides the energy required for active transport to move substances against their concentration gradient.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in large particles or liquids by engulfing them.

Front

What is the difference between exocytosis and endocytosis?

Back

Exocytosis is the process of moving substances out of the cell, while endocytosis is the process of bringing substances into the cell.
