Understanding the Fundamental Chemistry and Energy Flow in Living Cells

This educational overview explores the essential concepts of cellular biology. Students will learn that all organisms consist of one or more cells made up of molecules, and that cells arise from preexisting cells while performing vital life functions. Key topics will cover the four major elements (C, H, O, N) and four macromolecules (carbohydrates, proteins, lipids, nucleic acids). Additionally, the flow of energy and matter within cellular functions will be investigated, including photosynthesis and respiration, highlighting their importance to life and energy production.

Presentation Transcript

  1. Standard 2 • Students will understand that all organisms are composed of one or more cells that are made of molecules, come from preexisting cells, and perform life functions.

  2. Stand. 2 Obj. 1 • Describe the fundamental chemistry of living cells.

  3. Major ELEMENTS • C P • H S • N O

  4. Four Major Macromolecules • 1. Carbohydrates • 2. Proteins • 3. Lipids • 4. Nucleic Acids

  5. Enzymes

  6. Stand. 2 Obj. 2 • Describe the flow of energy and matter in cellular function.

  7. Troph = ? • Auto = ? • Hetero = ? • Example of both?

  8. Photosynthesis • CO2 + H2O + light  O2 + Sugar • This is why plants are so yummy!!!!!!!!!!!!!!!!!!!!!!

  9. Respiration (animals) • Sugar + O2 CO2 + H2O + ATP • Basically take a carbon sugar and make energy.

  10. Stand. 2 Obj. 3 • Investigate the function and structure of cells and cell parts.
