Lab: Inhibiting the Action of Catechol Oxidase By: Kimberly G. Introduction: In this lab‚ Mr. Greene ’s sixth period AP Biology class split into groups "to investigate inhibition of enzyme activity by specific chemicals called inhibitors" (1). Group three pondered this lab ’s inhibitor‚ phenylthiourea (PTU). Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it‚ and thus "wins" the position at the active site of the enzyme. The blocked

The study of cells has been limited by their small size‚ and so they were not seen and described until 1665‚ when Robert Hooke first looked at dead cells from an oak tree. His contemporary‚ Anton van Leeuwenhoek‚ crafted lenses and with the improvements in optical aids‚ a new world was opened. Magnification and resolving power limit

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

A central organizing concept in biology is that life changes and develops through evolution‚ and that all life-forms known have a common origin. The theory of evolution postulates that all organisms on the Earth‚ both living and extinct‚ have descended from a common ancestor or an ancestral gene pool. This last universal common ancestor of all organisms is believed to have appeared about 3.5 billion years ago.[21] Biologists generally regard the universality and ubiquity of the genetic code as definitive
