Liquid water, which is necessary for life as we know it, continues to exist on the surface of Earth because the planet is at a distance, known as the habitable zone, far enough from the Sun that it does not lose its water to the runaway greenhouse effect.
Classification is subject to change because science is an evolving subject. New things are discovered every year and thus changing the way we understand the world around us.
Enzymes are also known as Biological catalysts. An enzyme working at its maximum possible rate, where the substrate concentration is in excess is <span>V max.
</span><span>The reaction is slow because the molecules are moving slowly and they will not often collide with the active site of an enzyme, so the binding of an enzyme and substrate is rare.</span>
