What is an example of a carbohydrate?

Back

Starch is an example of a carbohydrate, which is used by plants to store energy.

Front

What is the plasma membrane?

Back

The plasma membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.

Front

What is the primary function of the plasma membrane?

Back

The primary function of the plasma membrane is to control what goes in and out of a cell, maintaining homeostasis.

Front

What surrounds every cell?

Back

The plasma membrane surrounds every cell, providing structure and protection.

Front

What are the main components of the plasma membrane?

Back

The plasma membrane is primarily made of phospholipids, proteins, and carbohydrates.

Front

What is the function of mitochondria?

Back

Mitochondria are organelles that produce ATP, the energy currency of the cell, through cellular respiration.

Front

What do both plant and animal cells have to make ATP?

Back

Both plant and animal cells have mitochondria to produce ATP.

Front

What is a primary use of lipids in the body?

Back

Lipids serve as a backup energy source and are important for cell membrane structure.

Front

What are lipids?

Back

Lipids are a group of hydrophobic organic compounds, including fats, oils, and steroids, that are important for energy storage and cellular structure.
