In this lab we study the activity of enzymes, a very important group of proteins. They speed up nearly all the important biochemical reactions within a cell (which would otherwise take an exceedingly long amount of time) and thus are an indispensable part of life on earth.
What's the difference between Autotroph and Heterotroph? Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis).
The rate of this reaction can be estimated by the speed at which bubbles of oxygen are produced. Enzymes are very sensitive to changes in temperature, pH, ion concentration and specific inhibitors. They are denatured by high temperatures (well below 100°C) when their three-dimensional shape is altered.

Oct 21, 2019 · A freshly cut apple eventually turns brown after being exposed to air because its cells contain an enzyme called polyphenol oxidase. When this comes in contact with oxygen present in the environment, it turns the phenolic compounds present in the apple tissues into brown-colored products
) was added. The enzyme breaks down the H 2 O 2 to produce water and oxygen which made the foam. Most of the foam was produced in the range 40 – 500C. Discussion: Enzymes are found in living cells and are made of proteins. As enzymes are made of protein if the temperature is too high it becomes damaged. The collision theory states that particles
Jun 18, 2020 · This lab will be driven by the research question, Do changes in temperature (from 0? C, 7? C, 19? C, 37? C, and 100? C) have an effect on the activity of the enzyme catalase (found in beef liver) in the breakdown of hydrogen peroxide? Hypothesis If liver is placed in different temperatures of 0? C, 7? C, 19? C, 37? C, and 100?
Lab 3-2: Enzyme Lab “How does enzyme concentration affect enzyme activity?” Introduction: Hydrogen Peroxide (H2O2) is a poisonous chemical that is continually formed as a by-product of reactions in living cells. Since it can damage cells, the cells must either get rid of it or change it into something that is non-toxic. If not, they risk death!
