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 is the role of mitochondria in muscle cells?

Back

Mitochondria provide massive amounts of ATP (energy) for movement and exercise in muscle cells.

Front

What is the structure of the cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer with hydrophilic (polar) heads facing outward and hydrophobic (nonpolar) tails facing inward.

Front

What is the function of cholesterol in the cell membrane?

Back

Cholesterol stabilizes the cell membrane, providing strength and flexibility.

Front

What are stem cells?

Back

Stem cells are undifferentiated cells that can differentiate into various types of specialized cells, such as bone or lung cells.

Front

What is a phospholipid?

Back

A phospholipid is a molecule that makes up the cell membrane, consisting of a hydrophilic head and two hydrophobic tails.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the role of the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum (ER) is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), as well as the transport of materials within the cell.

Front

What is the Golgi apparatus?

Back

The Golgi apparatus is an organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the function of the nucleus?

Back

The nucleus contains the cell's genetic material (DNA) and controls cellular activities by regulating gene expression.
