Carbohydrates are primarily responsible for energy storage in the form of sugars and starches.

Front

What is the role of proteins in the body?

Back

Proteins are essential for building and repairing tissues, making enzymes, and supporting immune function.

Front

What is a lipid?

Back

Lipids are biomolecules that include fats, oils, and waxes, which are important for energy storage and cell membrane structure.

Front

What is the function of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are responsible for storing and transmitting genetic information.

Front

What is the difference between voluntary and involuntary muscles?

Back

Voluntary muscles are under conscious control (e.g., skeletal muscles), while involuntary muscles operate without conscious control (e.g., heart muscles).

Front

Where does cellular respiration occur in the cell?

Cellular respiration occurs in the mitochondria, where glucose is converted into energy.

Front

What is the primary function of the mitochondria?

Back

The primary function of the mitochondria is to produce energy (ATP) through cellular respiration.

Front

What is the significance of water in biological systems?

Back

Water is essential for life, serving as a solvent, a medium for chemical reactions, and helping to regulate temperature.
