Questions and Answers

What is the role of the nucleus in a cell?

The nucleus stores genetic information, specifically DNA.

How do mitochondria contribute to energy production in the cell?

Mitochondria metabolize energy through cellular respiration, producing high-energy ATP.

What function does the Rough Endoplasmic Reticulum (Rough ER) serve in the cell?

The Rough ER is responsible for the synthesis of proteins.

Study Notes

Cell Structure and Function

Cells have a selectively permeable cell membrane, controlling nutrient and waste exchange. The membrane is composed of fats, proteins, and carbohydrates.
The nucleus houses the cell's genetic information (DNA).
Mitochondria are the sites of energy metabolism (cellular respiration). Enzymes facilitate the reactions, producing high-energy ATP.
Cytoplasm provides the cell's shape and environment for many reactions.
The rough endoplasmic reticulum (RER) synthesizes proteins.
The Golgi apparatus packages and secretes proteins produced by ribosomes (both free and bound to the RER). It also removes waste.

Organelle Structure and Functions

Many organelles (mitochondria, RER, Golgi, nucleus) are enclosed by or contain membranes made of fats and proteins. Thus, these macromolecules are vital for organelle structure.
