Flatworms absorb oxygen by diffusion mechanism through their
skin to the cells in their bodies. Since flatworms do not have a circulatory system,
their bodies' cells are positioned close to the skin to ease the uptake of
oxygen from surrounding fluids or water.
In the presence of an enzyme, the Activation energy is lowered. thus the reactions reaches the activation energy and the reaction is initiated faster and therefore completes faster than the reactions without enzymes. Enzymes lower activation energy, which allows a reaction to occur at a faster rate.
