Structure and function of macromolecules within a living organism ‘Some biological molecules in organisms are small and simple containing only one or a few functional groups‚ others are large‚ complex assemblies called macromolecules’ [1]. The term macromolecule is convenient because the bulk properties of a macromolecule differ from those of smaller molecules. These large chemical compounds have a high molecular weight consisting of a number of structural units linked together by covalent

of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration‚ also known as aerobic metabolism‚ occurs when oxygen is taken into the body and sent to all its cells; the oxygen is then used to break down food for energy (White and Campo 2008). Respiration can be experienced through several structures such as the lungs‚ tracheae‚ gills‚ and

most of the glucose is absorbed and is used to make energy‚ however‚ some glucose is converted to deoxyribose and ribose‚ these are essential for the building up of macromolecules such as DNA‚ RNA and ATP. Carbohydrates are also used for lipid metabolism. Nonetheless‚ despite of the fact that carbohydrates have many positive effects on the body it is argued whether or not carbohydrates are an essential nutrient. This essay will clarify the reason for why the body requires carbohydrates and why they

We tend to think of microbes as bad—pathogens that need to be killed—but new research suggests that storing scores of them is paramount to our health and metabolism. It appears that bacteria can affect energy absorption. The amount of energy is small‚ but researchers wonder if over time this could be a factor in weight maintenance. The world has become obsessed with destroying bacteria‚ attacking

❤ The main thing I stay away from is starchy carbs (no rice‚ potato‚ pasta‚ bread‚ cereal‚ etc.) and sweets (with a cheat day once a month because it’s good for your soul :D ). However it’s important to have some carbs (depending what they are) because they’re a great source of energy and certain carbs eliminate bloating. Like oatmeal. I have organic oatmeal with flax and cinnamon every morning to get my body going and to have some energy for the day. I usually eat it with 2 hard boiled eggs or a

A1. Role of Enzymes in Processes Enzymes are organic catalysts that help to speed up the breakdown of a molecule‚ such as fructose. The enzyme helps a chemical reaction take place quickly so that the reaction happens properly. In order for that to happen the enzymes process by the lock and key model‚ the lock is the substrate and the enzyme is the key. The active sites are specific to a certain substrate of a molecule‚ so the enzymes only have one job to do. The shape of an enzyme is not changed
