| Front | What is the role of protein carrier in the plasma membrane? |
| Back | Changes shape to move substances via facillitated diffusion |
| Front | How is water used for surface tension? |
| Back | At a water-air interface, the cohesive forces act in an inward direction, giving the water a high surface tension. This force causes the surface to occupy the least possible area - enbling small organisms to land on it |
| Front | What are the three steps of DNA replication? |
| Back | 1) DNA Helicase breakes H bonds between bases, seperating strands2) Free nucleotides attracted to complementary bases3) DNA Polymerase joins up free nucleotides via phosphodiester bonds to form daughter strand, forming a new double helix |
