The enzyme lipase breaks down the fat in dairy products such as full-cream milk for people who are lactose intolerant. Lipase acts on its specific substrate‚ lipids produces fatty acids. If enzyme concentration increases‚ random collisions between the substrates and active sites of enzyme increase due to the increasing
