though some drug metabolites are pharmacologically in active status. Inactive substance which has a metabolite that is active is referred to as a prodrug. Drugs are metabolized by the following processes; reduction‚ oxidation‚ conjugation‚ hydration‚ hydrolysis‚ condensation and isomerization. All these processes make the excretion of drugs easier from the body like that of a human being. For metabolism to occur‚ enzymes must be present. Enzymes are present in body tissues but they are concentrated in

Introduction: Being able to identify a particular bacterial species is important. It is very useful in knowing its risk of toxicity to humans or animals‚ its resistance or susceptibility to antibiotics‚ and determining how to control its growth or kill it altogether. The purpose of these procedures is to discovery the identity of an unknown microbe by observing its reactions to a barrage of chemical and physical tests. Different microorganisms react in different ways‚ due to their function‚ digestibility

The Uses of water in Living Things Topics I have chosen to cover: - Osmosis & Water potential - Condensation & Hydrolysis Reactions - Digestion – the importance of water - Blood and tissue fluid To emphasise the sheer importance of water in living things and to put the content of this essay in to perspective‚ I am firstly going to inform you that the human body is approximately 50-75% water. Without water our body would be unable to successfully perform the numerous complex reactions and

Because of this property‚ the food processing industry uses it to its advantage to break down lactose in milk for consumers that are lactose intolerant. Hydrolysis of whey also converts lactose into a very useful product like sweet syrup that can be used in various processes of dairy. The enzyme β-galactosidase can also be used in transglycosylation of lactose to synthesize galacto-oligosaccharides (GOSs)

fish are made up of 90% of water. There are many reasons why water is important to all living organisms. Metabolic role of water -Hydrolysis: Hydrolysis is the reaction of a compound with water‚usually resulting in the formation of one or more new compounds. Hydrolysis is an important reaction in plants and animals. The action of certain enzymes allows the hydrolysis of proteins‚ fats‚ oils‚ and carbohydrates. Medium for chemical reactions: All chemical reactions take place in some kind of liquid

and the enzymes active site is ready and waiting for another molecule of substrate. Amylase is an enzyme in human saliva and in other organisms and its substrate is starch. When the active site of amylase binds with the starch‚ hydrolysis takes place. When the hydrolysis (the breaking of a chemical bond with the insertion of the ions of a water molecule) of starch is complete you are left with a disaccharide called maltose. Enzymes are necessary for metabolic reactions‚ the question I pose is this--do

8.1 The totality of an organism’s chemical reactions is called metabolism. Metabolism is an emergent property of life that arises from interactions between molecules within the orderly environment of the cell. a. The chemistry of life is organized into metabolic pathways Metabolic pathways begin with a specific molecule‚ which is then altered in a series of defined steps to form a specific product. A specific enzyme catalyzes each step of the pathway. Catabolic pathways release energy by
