    Chromatography The Atomic Structure Atoms contain electrons which travel along electron shells‚ surrounding the nucleus that contains nucleons such as protons and neutrons. Electrons‚ neutrons and protons all make up an atom‚ they are called sub-atomic particles. Protons – has a relative charge of 1+ and a relative atomic mass of 1 Neutrons – are neutral‚ therefore the charge is 0. Also has a R.A.M of 1 Electrons – has a negative charge (1- )‚ and has a R

    Enzyme Report Case 1 - Hereditary Fructose Intolerance 1 & 2. Enzymes take on a variety of roles in the human body at the cellular level. Specifically‚ they aid in the breakdown of macronutrients such as glucose and fructose so that the body can use them. Although reactions within the body would occur without enzymes‚ enzymes provide control because the reaction is not needed all of the time. Enzymes function in specific environments such as temperature or pH; some enzymes are specific

    to its ability or tendency to lose a proton. There are very few strong acids. A strong acid is one that completely ionizes in water. In contrast a weak acid only partially dissociates. Examples of strong acids are hydrochloric acid (HCl)‚ hydroiodic acid (HI)‚ hydrobromic acid (HBr)‚ perchloric acid (HClO4)‚ nitric acid (HNO3) and sulfuric acid (H2SO4). In water each of these essentially ionizes 100%. The stronger an acid is‚ the more easily it loses a proton‚ H+. Two key factors that contribute

    Chemiosmosis. Chemiosmosis‚ by definition‚ is the diffusion of ions through a partially/selectively permeable membrane (down an electrochemical gradient). It is specifically refers to the flow of 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‚

    Question 2.1: (i) Calculate the number of electrons which will together weigh one gram. (ii) Calculate the mass and charge of one mole of electrons. * ------------------------------------------------- Answer (i) Mass of one electron = 9.10939 × 10–31 kg Number of electrons that weigh 9.10939 × 10–31 kg = 1 Number of electrons that will weigh 1 g = (1 × 10–3 kg) = 0.1098 × 10–3 + 31 = 0.1098 × 1028 = 1.098 × 1027 (ii) Mass of one electron = 9.10939 × 10–31 kg Mass of one mole of

    the potential energy of the electron is used by enzymes to pump hydrogen atoms inside the membrane. This creates a proton gradient. The proton gradient is caused by a higher concentration of protons inside the membrane than outside. This proton gradient is then used to add a phosphate onto ADP‚ turning it into ATP. The net effect of this process is to store the energy of the proton gradient in
