Cellular Transport

Front

What is cellular transport?

Back

Cellular transport refers to the mechanisms by which substances move into and out of cells, maintaining homeostasis and allowing for cellular functions.

Front

What is the primary goal of cellular transport?

Back

The primary goal of cellular transport is to maintain homeostasis within the cell.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells engulf substances from their external environment, bringing them into the cell.

Front

Does endocytosis require energy?

Back

Yes, endocytosis requires energy in the form of ATP.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials from the inside to the outside of the cell.

Front

When vesicles remove things from inside of the cell, what is this process called?

Back

This process is called exocytosis.

Front

What is osmosis?

Back

Osmosis is the passive movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

Does osmosis require energy?

Back

No, osmosis does not require energy; it is a passive transport process.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, relying on concentration gradients.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy (ATP) to occur.
