This could lead to an increase in capsule production and virulence by evading the host immune response (Tree et al., 2007).

  • Transport Protein

    2017-4-28 · Transport proteins generally perform two types of transport: "facilitated diffusion," where a transport protein simply creates an opening for a substance to diffuse down its concentration gradient; and "active transport," where the cell expends energy in order to move a substance against its concentration gradient. Function of Transport Protein
