AP Biology Lab: Catalase (Enzymes) Abstract In this laboratory exercise‚ studies of enzyme catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme

Here I will make a solution from the samples in order to carry out the identification tests. In order to turn my soil samples

AP Bio Block B Photosynthesis Lab 12/6/12 Introduction: Photosynthesis is affected by light intensity‚ water‚ and temperature. Plants grow more abundantly because the weather is warm. Carbon Dioxide given off by animals is consumed by plants that replace the oxygen animals take it. Experimentation will help understanding how plants are vital because of the oxygen they release. If leaf disks in the experiment release oxygen‚ they will undergo photosynthesis and float. If

and developmental processes‚ thus it is critical for plants to optimize the ethylene production at developmental transitions as well as during stress response. Ethylene is derived from the amino acid methionine‚ which in the first step is converted to S-adenosyl-methionine (AdoMet) by AdoMet synthetase3‚4. The 1-Aminocyclopropane-1-Carboxylic acid Synthase (ACS) catalyzes the conversion of AdoMet to 1-aminocyclopropane-1-carboxylic acid (ACC)5‚ which is the rate-limiting step in ethylene biosynthesis

(Staudt 80). In this lab‚ solubility in water‚ acidity‚ and odors of carboxylic acids will be observed. Also‚ esters will be produce and odors will be detected from the product. Finally‚ saponification will be learned.

Part 1 of the experiment was done by 2 different methods. Method 1 was with a force sensor‚ springs‚ and a weight hanger in which masses of 100 gram increments were added (up to 600 grams).

potential to damage crops extensively‚ and thus‚ damage society as well through shortage of food or even famine. In addition‚ in countries that depend on the production of agricultural goods like Canada‚ the effects of acid rain can be tremendous. In this lab‚ we have chosen to examine the effects of acidic and basic environments on radish plants (Raphanus sativus)‚ by implementing varying pH levels of buffer solution into the soil. We have allotted a total of four days (Tuesday‚ April 10‚ 2012- Friday April
