enzymes are found in living cells. In addition to making life possible‚ many enzymes have numerous applications that affect our daily lives in other ways such as food processing‚ clinical diagnoses‚ sewage treatment‚ and the textile industry. In this activity you will investigate how a particular factor influences the action of an enzyme. Conditions: Students are NOT required to design an experiment. Experimental design has been provided for you to use instead. You are however required to submit

Temperature and Thermometers The Temperature of an object is a measure of the hotness or coldness of that object. An alternative way to think of temperature is to say that “the temperature of an object is a number – on some manmade scale – that indicates the hotness of the object”. ‘Hotness’ in turn is a measure of the kinetic energy of the molecules of the material. Note: You must use the term ‘hotness’.* The SI unit of temperature is the Kelvin (K)* Relationship between degrees Celsius

imbalance presents a high opportunity for export of organic fruit juice from Uganda. Fruits and farm produce are wasted or sold at very low prices during peak seasons due to inadequate storage facilities and lack of effective processing or preservation techniques‚ leading to high wastage levels. Juice production not only serves to add value to agricultural export but also serve as a way to prevent wastage of excess fruits. The juice industry has an opportunity to contribute to the Ugandan economy

Rape is a difficult subject to explain to others because it is traumatic experience that people not involved will be unable to deal with the situation. Laurie Anderson’s novel Speak focuses on this very issue. The protagonist‚ Melinda Sordino‚ must face the challenges of high school‚ family issues‚ and the inability to express herself. Mr. Freeman‚ David Petrakis‚ and sports are the things Melinda relies on to overcome the past that haunts her. Mr. Freeman is a factor that motivates Melinda Sordino

of a Potato Mishal Hasan Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation‚ several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it was isotonic. Anything above caused the potato to gain weight showing that it was a hypotonic solution and anything below caused the potato to lose

University’s wooded areas‚ the oldest was created in 1989 the second was created in 1994 and the youngest plot was created in 1999. For the hypothesis to be tested‚ there were soil PH meters to test the amount of PH in each plot’s soil. The hypothesis was incorrect; there was not a significant difference in the means of the PH from the oldest plot compared to the youngest plot. Introduction The definition of vegetation is plants considered collectively especially those found in a particular area

Ben Zaré 9MK Biology Investigation - Osmosis in Potato Cells 9/7/04 Section 1 Planning Aim What is the aim of your experiment? What do you want to find out? The aim of this experiment is to investigate how potato tissue changes when placed in sucrose solution of different concentrations. Therefore‚ I want to find out if and how osmosis differs‚ when the concentration is changed. Variables What is the variable you are going to change in the experiment?

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a

Potato Enzyme Lab Enzymes are protein catalysts that speed up chemical reaction in living organisms. The purpose of this lab was to; observe the breakdown of hydrogen peroxide toxin by potato’s enzyme catalase‚ determine factors that influence how quickly the reaction takes place‚ and determine factors that influence how well enzymes function. The first test‚ we were supposed to see what would happen when we add sand in hydrogen peroxide. We filled a test tube with 5mL hydrogen peroxide and we added
