Assessment of Catalase Function Lab Introduction The purpose of this lab report was to test and measure the rate of substrate destruction by an enzyme‚ we tested the destruction of hydrogen peroxide by the enzyme catalase. Hydrogen peroxide is a poisonous by product of metabolism that can damage cells if it is not removed. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide into water and oxygen gas. H2O2 + catalase → H2O + O2 A catalyst is a substance that lowers the

Research Project: Potato The potato originated in the South American Andes‚ but its heartland of wild genetic diversity reaches from Venezuela‚ Colombia‚ Ecuador‚ Peru‚ Bolivia‚ Argentina‚ Chile‚ Uruguay‚ Paraguay‚ southern Brazil‚ northward into Central America‚ Mexico‚ and the southwestern United States. Potato was first cultivated between 3 and 7 thousand years ago‚ some scientists believe they may have grown wild in the region as long as 13‚000 years ago. Potato is the third most important

Catalase Enzyme Lab Samiya Hussein March 9‚ 2012 Introduction In order to receive the necessary amounts of energy required for daily function‚ the digestive system must break down proteins‚ fats and carbohydrates. In doing so‚ the body produces poisonous chemicals; however‚ the cells aren’t harmed. This is because enzymes are used to break down these chemicals. The name of the enzyme that was the main focus of the lab is catalase. Catalase is responsible for catalyzing hydrogen peroxide

Frozen (2013) Olivia Tsetsos Disney’s new musical extravaganza does not disappoint with yet another timeless classic. The 3-D adventure wants to subside the platform of the typical Disney princess movie while simultaneously remaining true to their winning formula. The film encourages women to support each other- a crucial message when petty‚ vulgar girls seem to be so common. After the kingdom of Arendelle is set into eternal winter by Queen Elsa‚ her quirky sister Anna unites with an ice maker

Animated Me FROZEN PICTURE It is seemingly difficult to rest in God when life keeps us scrambling from one demand or crisis to the next. Yet those are the very times when we are most in need of depending utterly on him. Indeed‚ He will always make a way. Sometimes God gives us “frozen pictures” of happy times to replace dark thoughts or unhappy memories of loved ones we have lost to death or to alienation. Dwelling on troubling images only makes the heartache worse‚ and it can take our eyes

From the graphs‚ it is evident that an increase in both catalase concentration and substrate concentration resulted in a higher rate of reaction or‚ as observed in the kPa graphs‚ a higher volume of O2(g) formed at the end of the 5 minute trial. Interestingly‚ it should also be noted‚ as it was mentioned in the Figure 2‚ that the trend for the 6mL of 3% H2O2(aq) was more of a linear trend than an exponential decay‚ steadily rising until the end of the 5 minute trial. From this‚ it can be inferred

launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia oleracea (Spinach)‚ Brassica oleracea (Broccoli)‚ Solanum tuberosum (Russet Potato)‚ Malus domestica (Apple)‚ and Allium cepa (Onion). The five different catalases from the sources will all be used
