Presentation Transcript

  1. Biomolecules and Photosynthesis Biology Essential Standard 4.1 and 4.2

  2. Background • Biomolecules, commonly referred to as “organic molecules” or “biological molecules” all contain carbon. • They are the four molecules of life. • The Miller-Urey Experiment discovered that these molecules (especially) amino acids existed in the early conditions of Earth

  3. carbohydrates • Building Blocks: Monosaccharides (simple sugars) • Function: Energy production • Examples are: starches, sugar, breads, pasta • Glucose, sucrose, fructose, dextrose, maltose • The suffix “--ose” means sugar • Monosaccharides (simple sugars) join together to make disaccharides and polysaccharides.

  4. Lipids • Building blocks are fatty acids • Function: insulation, make up the cell membrane, protects vital organs • Examples: mayonnaise, vegetable oil, canola oil, olive oil, steroids, cholesterol

  5. Proteins • Building blocks of proteins are amino acids. • Function: • Examples: enzymes (to speed up reactions) All enzymes are proteins, but not all proteins are enzymes.

  6. Nucleic acids • Building Blocks are: nucleotides (phosphate, sugar, base) • Function: Storing genetic information and protein synthesis • Example: DNA and RNA
