HUMAN WILDLIFE CONFLICTS The relationship between man and wildlife‚ historically and prehistorically has been often antagonistic. People have hunted wild animals for food all over the world. Animals have attacked agricultural crops and livestock since the beginning of agriculture and settled lifestyle about 10‚000 years ago. Many wild animals are potential competitors to humans for food resources or threats to human life. Wild animals that directly compete with humans for resources such as food

Experiment 2: Starch Hydrolysis by Amylase Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2].

ABSTRACT: Medicinal plants are potential sources of new drugs to improve the treatment of diseases whose treatment is associated to anti-oxidative agents. In the current study‚ we carried out a comparative analysis of the antioxidant activities of extracts of the selected leaves of 6 common medicinal plants. Total Ascorbic Acid Content‚ Total Carotenoid Content‚ Antioxidant potential using FRAP assay and Total Phenol Content was quantitatively estimated from leaves of Rauvolfia serpentina‚ Cymbopogon

Recently (2011) a paper was published by Christopher J. Johnson et al who discovered species of lichen that effectively degrade PrPC and PrPSC in vitro. By mixing infected and control brain homogenates with lichen extracts‚ they showed significantly reduced immunoreactivity of the PrP protein when precipitated with a PrP-specific antibody. The authors further showed that the likely agent causing this degradation was a serine-protease. Variant

Sonia St James Investigation: Factors that affect the outcome of enzyme activity Introduction In this project I will monitor the rate of activity of Catalase. Catalase is an Enzyme which in the right conditions catalyses the decomposition of Hydrogen Peroxide into water and oxygen; 2H2O2 + Catalase >>> 2H2O + O2 Catalase is found in all cells and protects them from Hydrogen Peroxide which is a dangerous waste product that needs to be eliminated. Without Catalase living things could not survive

Effect of Enzyme and Substrate Concentration on Reaction Rate by Zachary A. Poché Biology 155 Laboratory October 15‚ 2014 Lab Partners: Cade White‚ Hannah Ragas‚ Russheka Aremillion ABSTRACT In order to increase the reaction rate‚ substrates attach to the active site of enzymes which decrease the activation energy required to convert substrates to products. We examined the effect of enzyme concentration and substrate concentration on the overall rate of the reaction. To determine
