What are carbohydrates?

Back

Carbohydrates are biomolecules made of carbon, hydrogen, and oxygen. They are a primary source of energy for the body and are found in foods like pasta, bread, and fruits.

What role do proteins play in the body?

Back

Proteins are essential for building and repairing tissues, making enzymes, and supporting immune function. They are made up of amino acids and are found in foods like meat, beans, and nuts.

Front

What are lipids?

Back

Lipids are a group of biomolecules that include fats, oils, and waxes. They are important for storing energy, making up cell membranes, and serving as signaling molecules.

Front

What is the function of enzymes?

Back

Enzymes are proteins that speed up chemical reactions in the body. They lower the activation energy needed for reactions to occur, making processes like digestion more efficient.

Front

What are nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are biomolecules that store and transmit genetic information. They are made up of nucleotides and are essential for heredity and protein synthesis.

Front

How do carbohydrates provide energy?

Back

Carbohydrates are broken down into glucose, which is used by the body as a quick source of energy. They are especially important for athletes and active individuals.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids. There are 20 different amino acids that combine in various ways to form proteins.

Front

What is the structure of lipids?

Back

Lipids often have long fatty acid chains and can be saturated (with single bonds) or unsaturated (with double bonds). They are hydrophobic, meaning they do not mix well with water.

Front

What is the importance of cell membranes?

Back

Cell membranes are crucial for protecting the cell and regulating what enters and exits. They are primarily made of lipids, specifically phospholipids.

Front

How do proteins contribute to muscle building?

Back

Proteins provide the necessary amino acids for muscle repair and growth after exercise. Consuming protein-rich foods helps athletes build and maintain muscle mass.
