Front

What is the powerhouse of the cell?

Back

Mitochondria are known as the powerhouse of the cell because they produce ATP, the energy currency of the cell.

Front

What are the main processes involved in cellular transport?

Back

The main processes of cellular transport include passive diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis.

Front

What is NOT a function of the cell membrane?

Back

Synthesizing proteins is NOT a function of the cell membrane.

Front

What is the basic unit of all living organisms?

Back

The basic structural, functional, and biological unit of all living organisms is the cell.

Front

What are the two main types of cellular transport mechanisms?

Back

The two main types of cellular transport mechanisms are passive transport and active transport.

Front

Define passive transport.

Back

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

Front

Define active transport.

Back

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

Front

What is facilitated diffusion?

Back

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

Front

What is endocytosis?

Back

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

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials to the outside environment, often involving vesicles.
