lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.

plants absorb water from the soil by osmosis. root hair cells are adapted for this by having a large surface area to speed up osmosis. the absorbed water is transported through the roots to the rest of the plant where it is used for different purposes: it transports dissolved minerals around the plant.
