Level 5 · Science S5.1

Molecules and cells

Life runs on a few kinds of molecule working together inside cells.

Planned. This book is not written yet. Below is its plan, which a teacher can already use.

You are ready for this book if

You can explain how enzymes work and what changes their rate.

The plan

  1. S5.1.1 Water and carbohydrates
    • Explain how hydrogen bonds give water properties that support life
    • Compare the structures and uses of starch, glycogen and cellulose
  2. S5.1.2 Lipids and proteins
    • Describe the four levels of protein structure
    • Explain how the structure of phospholipids forms membranes
  3. S5.1.3 Enzyme action and inhibition
    • Explain how competitive and non-competitive inhibitors work
    • Interpret rate graphs for substrate concentration and temperature
  4. S5.1.4 DNA, RNA and replication
    • Describe the semi-conservative replication of DNA
    • Compare the structures of DNA and RNA
  5. S5.1.5 Protein synthesis
    • Explain transcription and translation in order
    • Use a codon table to translate a short mRNA sequence
  6. S5.1.6 Cell ultrastructure
    • Relate each organelle in eukaryotic cells to its job
    • Compare prokaryotic and eukaryotic cells in detail
  7. S5.1.7 Membranes and transport
    • Describe the fluid mosaic model of the membrane
    • Explain water potential and predict the direction of osmosis
  8. S5.1.8 The cell cycle and cancer
    • Describe the stages of the cell cycle and mitosis
    • Explain how faults in cell cycle control lead to cancer

For parents and teachers

Level 5 fits learners who can already: read a textbook. use functions and graphs. In many schools that is about 17 to 20, but start wherever the learner is.
