<em><u>Centrioles</u></em> are organelles that are only found in animal cells.
<u><em>Centrioles are important organelles that functions by helping the process of cell division in animal cells.</em></u> This is by helping the formation of spindle fibers whose role is to separate chromosomes during cell division.
Additionally, <em><u>centrioles also play a very important role in celiogenesis, the formation of cilia and flagella on the surface of cells.</u></em> The cilia and flagella enhance the movement of cells.
The enzyme 's active site binds to the substrate. Increasing the temperature generally increases the rate of a reaction, but dramatic changes in temperature and pH can denature an enzyme, thereby abolishing its action as a catalyst.
Transport proteins- an example of a protein in the plasma membrane is integral proteins, which main function is to transport molecules across the membrane. Hope this helps :)
