Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.
<span>Evidence that supports this includes the lack of true tissue in sponges and the close similarity between choanocytes and choanoflagellates.</span>
True, only plant cells have vaculoes.
