lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable after the experiment
Premium Enzyme Chemical reaction Metabolism
Enzymes are globular proteins that are synthesized by the ribosomes in a cell. They act as catalysts during biological reactions; therefore‚ enzymes are able to speed up these reactions without undergoing a permanent change themselves. These proteins are able to do this by lowering the activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed

Restriction enzymes (or restriction endonucleases)‚ originally isolated from Haemophilus influenzae in 1970‚ are enzymes within a cell that cleave foreign DNA within a specific and predictable nucleotide sequence (known as a restriction site) regardless of the source of such DNA. Such restriction

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

on enzyme activity show that as the independent variable‚ pH‚ increases the dependent variable‚ percentage transmission‚ decreases. This is shown in the results as at the lowest pH‚ pH 4.0 the average percentage transmission is at its highest at 97%. At the highest pH‚ pH 8.0 the average transmission is 78.5%. This is also supported from the graph as it produces a negative gradient showing that as the percentage transmission will decrease with an increasing pH. This happens because the enzyme trypsin

protease enzyme on exposed developed film Plan Aim: The aim of the experiment is to find out what effect temperature has on the action of a protease enzyme on exposed developed film. Enzymes are biological catalysts. They are made in livings things built up by amino acids to make protein. Enzymes are able to speed up reactions and can repeat reactions. There are various factors that affect the activity of enzymes they are: "Y Temperature "Y pH "Y Specificity "Y Concentration of enzyme or substrate
