of two ATPs are produced as the process uses two ATPs and produces four. Glycolysis consists of ten chemical reactions; each reaction is catalysed using a different enzyme. Oxygen is not required during glycolysis so it is considered anaerobic respiration. Glycolysis must be regulated so that energy is produce only when required. During glycolysis there are three enzymes that catalyse or inhibit the rate of reaction. These are hexokinase‚ phosphofructokinase and pyruvate kinase. During the first

Action of enzymes as catalysts in biochemical processes * Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that‚ they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et‚al 2008). * The second function is‚ they increase reaction rates

The human body is a very complex working system and it requires a lot of energy to function properly. The human body eats food molecules that contain nutrients in order to get the energy needed to function. Once these food molecules are broken down in the human body some of the nutrients are made into glucose‚ which is an energy source. This glucose is not quite usable as one whole thing so our body breaks down even more into other molecules like pyruvate. Eventually the human body needs to make

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric

protons through the inner mitochondrial membrane. The main theory behind chemiosmosis is call Chemiosmosis theory‚ and was developed by Peter Mitchel in 1961. Here is a brief outline of the theory (now pretty much accepted as fact): Throughout respiration carrier molecules (NAD and FAD) are produced‚ which carry electrons. These pass electrons through to a chain of proteins which also act as electron carriers (This whole chain‚ from NAD and FAD to the proteins is called and electron transport chain
