results. This is due to the enzymes being most active at 60ᵒC‚ it was that results were going to be most active at the 41ᵒC which is close to human body temperature. When we compare the enzyme in the low temperatures to the enzymes in the higher temperature we observed that the enzymes were functioning at a significantly reduced rate at the 24ᵒC temperature and was completely inactive at the 0ᵒC temperature. Whereas when we compare to the higher temperatures (60ᵒC) the enzymes should have functioned

There are no formal or normative standards for the TAT‚ but the simplest procedure for studying TAT responses is by using the inspection technique. Interpreting the TAT pictures are best seen psychologically as a series of social situations and interpersonal relations. It is also important to consider that all characters in the stories are projected aspects of the self‚ so they may represent the ideal‚ real‚ or feared self. The absence of positive outcomes indicates possible depression and hopelessness

Enzymes are catalysts that increase the rate of chemical reactions organisms‚ allowing cells to break or build things instantly. The structure of an enzyme is essential to its function. Enzymes are proteins‚ made up of 100-1000 amino acids bonded together in chains. These chains are folded/coiled into a unique 3-D structure that allows them to bind to a reactant‚ called a substrate at an active site. Enzymes are flexible‚ and therefore can change it’s shape to better accommodate its substrate; this

Enzyme Activators and Inhibitors Lucia House AP Biology‚ Block 4 Mr. Trice October 18‚ 2012 Introduction: Metabolism is the totality of all of an organism’s chemical reactions. Chemical reactions occur due to enzymes‚ a substance which acts as a catalyst in driving chemical reactions in order to produce a desired product (Campbell and Reece‚ 2002). A catalyst is usually a protein; however‚ some catalytic molecules counter this generalization. A discovery made in the early nineteen- nineties

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

joules‚ F is the force in newtons‚ and delta d is the displacement in meters. If Ben Roethlisberger applies a force of 1050N on a football that travels 70 yards(64.008 meters)‚ then it is possible to calculate the work Ben Roethlisberger has done using the formula. W = 1050 x 64.008‚ W = 67‚208.4 joules. Therefore‚ Ben Roethlisberger must use 67‚208.4 joules of work to throw the football 70 yards down the

– Restriction Enzyme Digestion To begin this experiment‚ the DNA molecules must be cut into smaller fragments with distinct enzymes called Restriction Enzymes through a process called Restriction Enzyme Digestion. Four microtest tubes were labeled 1 through 4 and added 10 µl of Enzyme Reaction Buffer to each of the four reaction tubes using a micropipette. DNA‚ and Enzyme 1 and 2‚ were then added to the reaction tubes using a new micropipette tip for each transfer of DNA and enzyme (refer to figure
