Which part of an animal cell helps control all chemical reactions within the cell?
enzymes are needed to control chemical reactions within cells because the enzymes acts like catalysts. They basically speed up the reactions within the body, and within the cells, so there fore they help the body maintain its internal environment (homeostasis). -Grade 12 Bio student (exact question came on a handout :P)
When something is alive, there are chemical reactions going on constantly within it. The technical definition of being dead is that of chemical equilibrium. When a system (for example, a beaker with chemicals inside it, or an animal) is in chemical equilibrium, there is no reaction that can take place without an input of energy. Since an animal in chemical equilibrim cannot do anything, it is considered completely dead. So, in short, dying (that is…
metabolic reactions are basically vital chemical reactions that must occur within a cell, in order for it to survive. for a chemical reaction to occur, the molecules that constitute the chemicals must be dissolved in a solvent. water is a universal solvent and is highly abundant in organisms. it is for this reason, that many metabolic reactions occur in water.
