Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific

Influencing Natural Selection Influencing Natural Selection BIO/101 Influencing Natural Selection Introduction/Purpose The purpose of this experiment is to test the hypothesis that small bird’s physical characteristics can greatly impact their species population growth over time. Using the Finch as a test subject for multiple trial runs on a simulated computer system we can alter the characteristics of the finch and run diagnostics for two completely different locations and set

Evolution Lab BIO/101 Pooja Thakur 7-23-12 Evolution Resulting From Natural Selection INTRODUCTION The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100‚ 200‚ and 300 years. By manipulating parameters that influence natural selection‚ the effects that natural selection have on the evolution process can be studied. HYPOTHESES • The size

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population‚ and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining

grouped into primary events that include the metabolism of residual lactose and of lactate and citrate. There are different types of cheeses because there are many enzymes that are used to make the cheese‚ and also there are endless forms of molds that help age cheese giving each cheese its distinctive taste‚ texture and appearance. Enzymes are used in many food production processes to speed up the chemical reactions‚ which reduces water usage and energy consumption. The original objective of cheese
