Active Transport Flashcard

Front

What is active transport?

Back

Movement of molecules from low to high concentration using energy.

Front

Which energy source is required for active transport?

Back

ATP.

Front

What type of proteins are essential for active transport?

Back

Transport proteins.

Front

What is the primary function of the contractile vacuole in a paramecium?

Back

To remove excess water from the cell.

Front

How does active transport differ from passive transport?

Back

Active transport requires energy to move molecules against their concentration gradient, while passive transport does not.

Front

What is the role of ATP in active transport?

Back

ATP provides the energy needed for the transport of molecules against their concentration gradient.

Front

Can active transport occur without transport proteins?

Back

No, transport proteins are essential for the process of active transport.

Front

What is an example of a substance that is transported via active transport?

Back

Sodium ions (Na+) are often transported out of cells against their concentration gradient.

Front

What is the significance of active transport in cellular function?

Back

Active transport helps maintain concentration gradients essential for various cellular processes.

Front

What is the difference between primary and secondary active transport?

Back

Primary active transport directly uses ATP for energy, while secondary active transport uses the energy from the movement of other molecules.
