Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one

The Biological Importance of Water In Living Organisms Water is the most important molecule in cells‚ the whole organisms and on earth‚ this is due to it’s unique physical and chemical properties. ” A water molecule‚ because of its shape‚ is a polar molecule. That is‚ it has one side that is positively charged and one side that is negatively charged”(1). A water molecule is made up of two hydrogen atoms and one oxygen atom and the bonds between these atoms are single covalent bonds. Fig 1. The
