In Lacsap’s Fractions‚ En(r) refers to the (r+1)th term in the nth row. The numerator and denominator are found separately‚ therefore to find the general statement‚ two different equations‚ one for the numerator and one for the denominator‚ must be found. Let M=numerator and let D=denominator so that En(r) = M/D. To find the numerator for any number of Lacsap’s Fractions‚ an equation must be made that uses the row number to find the numerator. Because the numerator changes depending on the row

electron travels with a proton‚ hydrogen atom NAD+: functions as an oxidizing agent Hydrogen atom transferred here first most versatile electron acceptor Traps electrons from glucose by enzymes (dehydrogenases) to remove pair of hydrogen atoms(2 electrons & 2 protons) from substrate to oxidize it‚ then the enzyme delivers the 2 electrons & 1 proton (the other is released as hydrogen ion) to its coenzyme NAD+ The NAD+ has now neutralized its charge and is reduced to NADH Electron Transport Chain:

26/05/2014 Biology “Enzyme Activities” Introduction: Enzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart as needed. This is how a cell grows and reproduces. At the most basic level‚ a cell is really a little bag full of chemical reactions that are made possible by enzymes (Brain)

Reactions Enzymes are proteins found in living things that speed up chemical reactions. They aid in nearly all metabolic processes‚ such as food digestion‚ molecule synthesis‚ and the storage/ release of energy. An enzyme speeds up the rate of the chemical reactions by lowering the reaction’s activation energy‚ which means that by definition‚ an enzyme functions as biological catalyst. The activation energy is the energy that is used to get a reaction started. The function of an enzyme is dependent

experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are made up of proteins which

Sang Kim Enzyme Catalyst Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A‚ B‚ C‚ and D. In activity A‚ the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction‚ to study the characteristics of an enzyme mediated reaction‚ and to observe the effect of heat on enzyme activity. The purpose of activity B is to use the Titration Protocol to determine the initial amount of H 2O2 present
