Cells
Providing structural support, facilitating energy production, and enabling reproduction
Define Macromolecule
Macromolecules are large, complex molecules essential for life, typically formed by joining smaller subunits called monomers into long chains called polymers.
Importance of stem cells
Stem cells are vital because they can self-renew and differentiate into specialized cells, acting as the body's internal repair system.
Stores genetic information
Nucleic Acids: Polymers of nucleotides (DNA and RNA) that store and transmit genetic information to guide protein synthesis.
Importance of White Blood Cells
White blood cells protect the body against infections, viruses, bacteria, and foreign invaders
Hair & Nail strength
Proteins: Chains of amino acids that act as enzymes, hormones, and structural components (e.g., keratin, antibodies, hemoglobin).
Nerve cells are the fundamental units of the nervous system, transmitting information throughout the body using electrical impulses and chemical neurotransmitters.
Lipids: Hydrophobic molecules including fats, oils, waxes, and steroids, which are critical for long-term energy storage and cell membrane integrity (e.g., phospholipids).
Importance of red blood cells
Primarily responsible for transporting oxygen from the lungs to body tissues and removing carbon dioxide waste via hemoglobin.
Primary energy source
Carbohydrates: Composed of monosaccharides (sugars), they serve as primary energy sources and structural materials (e.g., glucose, starch, cellulose, glycogen).
