“life.” How do we study life? Life is studied in biology‚ biology is the study of life because in biology we analyze specimens‚ like micro organisms and bigger organisms like the human body through microscopes. We also further analyze the 6 characteristics of life in biology. By experimentation‚ and observing various things like cells and animals‚ and trying to establish fact by finding a pattern.. Why do we study about life in biology? Well we study

Biology- Maintaining a Balance Summary 1. 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
