The importance of shapes fitting together in cells and organisms.

The importance of shapes fitting together in cells and organisms.

1. enzymes, enzyme substrate complexes

   • digestion + assimilaition
   • DNA helicase + polymerase, acetylcholinesterase for nerves,
   • photosynthesis and respiration

2. apoplastic and symplastic pathwways

   • leaf structure
     • maximises gas exchange in mesophyll layer, shape of palisade cells for max photon absorb, guard cells + stomata

3. DNA

   • nucleotides, pentose sugar, base, phosphate, DOUBLE HELIX
     • good structure, physically and chemically.

4. immunity, phagocytosis, antibodies and antigens

5. Carbohydrates, protein, lipids structures

   • phospholipid bilayer, importance for its processes

6. the heard - the values

   • prevents back flow, max efficiency, less stress for heart + max nutrients and stuff for cells for reap...

7. muscles

   • structure, myofibrils, sarcoplasmic reticulum, sarcoplasm, muscle fibres, myosin heads, actin
