CORE ONE: MAINTAINING A BALANCE • IDENTIFY THE ROLE OF ENZYMES IN METABOLISM‚ DESCRIBE THEIR CHEMICAL COMPOSITION AND USE A SIMPLE MODEL TO DEMOSTRATE THEIR SPECIFITY ON SUBSTRATES. Enzymes are biological catalysts this means that they lower the energy required to start a chemical reaction within a cell but don’t get used up by that reaction. Every reaction and process in the metabolism of the cell is controlled by a specific enzyme. Enzymes are globular proteins whose shapes are specialised

increases‚ the level of sexual desires increases‚ but performance decreases. Alcohol also affects the pituitary gland by inhibiting the secretions of the Antidiuretic hormone (ADH)‚ which also effects urine excretion. The Antidiuretic hormone works on the kidney to help reabsorb water. When alcohol has been drunk‚ the ADH levels in the body drop‚ resulting in the kidneys being unable to reabsorb a large amount of water‚ and producing more urine (Blood Alcohol information 2006-2010).

An overview of the nervous and endocrine systems‚ their functions and how together they regulate homeostasis The endocrine system is the internal system of the body that deals with chemical communication by means of hormones‚ the ductless glands that secrete the hormones‚ and those target cells that respond to hormones. The endocrine system functions in maintaining the basic functions of the body ranging from metabolism to growth. The endocrine system functions in long term behavior and works

* A reactant in an enzyme-catalyzed reaction is called a substrate. The area of the enzyme that binds to the substrate is called the active site - where the action takes place. * Cofactors and coenzymes are small molecules or ions that help enzymes to act.
