Front

What are biomolecules?

Back

Biomolecules are organic molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the primary function of carbohydrates in the body?

Back

Carbohydrates provide a quick source of energy and are important for cellular functions.

Front

What type of cells are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and organelles, found in organisms like plants, animals, and fungi.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions in the body without being consumed in the process.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What are the main components of cell theory?

Back

1. All living things are made of cells. 2. The cell is the smallest unit of life. 3. All cells arise from pre-existing cells.

Front

What is the function of lipids in the body?

Back

Lipids provide long-term energy storage, make up cell membranes, and serve as signaling molecules.

Front

What is the role of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, carry and transfer genetic information.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
