Q&A

• What are the major elements in biomolecules and why are they important?

  The major elements in biomolecules include Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorous (CHONP), and their arrangement greatly impacts the function of biomolecules. This arrangement is essential for the diverse roles biomolecules play in cellular activities.

• What functions do nucleic acids serve in cells and organisms?

  Nucleic acids like DNA and RNA are crucial for coding traits and directing cell activities. They are important for genetic coding, have nucleotides as their monomers, and play a role in cell signaling, immunity, and metabolic processes.

• Why are proteins essential for cells?

  Proteins are crucial for cell structure, tissue composition, and can be found in cell membranes. They also have various functions such as cell signaling, metabolism, immunity, and genetic coding.

• What role do lipids play in cells?

  Lipids are diverse and generally hydrophobic. They contribute to cell membrane structure with phospholipid bilayers, serve as a major energy source for cells, act as hormones, and are important for thermal regulation and insulation.

• What are monosaccharides, disaccharides, and polysaccharides?

  Monosaccharides are the building blocks of carbohydrates, like glucose. They can combine to form disaccharides (e.g., maltose) and multiple monosaccharides create polysaccharides (e.g., starch, cellulose). Carbohydrates play a vital role in cellular respiration and are important for the structure of cell walls in plants and fungi.

• Why are biomolecules important to cell structure and function?

  Biomolecules are vital to the structure and function of cells and organisms. They play a crucial role in energy production, cell signaling, genetic coding, and various cellular processes.

• What are biomolecules?

  Biomolecules are molecules found in food that are essential for life. They include carbohydrates, lipids, proteins, and nucleic acids.
