Please answer all parts of the question about the effect of an increasing temperature changes on the effectiveness of catalase enzyme action
a) What constitues an organism's metabolism?
b) What role do enzymes play in an organism's metabolism? Be sure to classify an enzyme as a biological catalyst (you may want to include the definition of a catalyst as well).
c) what factors are known to control enzyme action?
d) identify what a substrate is and how enzymes act upon them.
e) what is hydrogen peroxide? Where is it produced and why is it toxic to living cells?
f) What is hydrogen peroxide broken down into in the presence of catalase enzyme?
Explanation / Answer
Answer a. The biological reactions taking place in our body are known as the metabolic reactions. The phenomenon is known as the metabolism.
They can be catabolic or anabolic.
In catabolic reactions, the larger molecule is broken down into the smaller ones. Like as it happens in the digestion process.
In Anabolic reactions, a larger molecule is formed by joining many smaller molecules together. Example is starch synthesis in the photosynthetic reaction.
Answer b. Enzymes play a very very important role in catalysing the metabolic reactions. Majorly the reactions taking place inside our body are the enzyme catalysed reactions. Each metabolic reaction requires a specific enzyme.
Enzymes work as biocatalysts in our body, means they increase the speed of the reaction as a result, the products are formed within a quick span of time. They do this, by lowering the amount of activation energy required by the substrates.
Answer c. There are primarily 2 factors that controls the enzymic activity. The pH and the temperature. There is an optimal pH and temperature for each enzyme, at which the enzymatic activity is maximum.
High temperature can permanent disrupt the structure of enzymes by denaturation.
Answer d. Substrates are actually the reactants. Each enzyme has a specific site called active site with which it binds to a specific substrate.
For example the enzyme salivary Amylase in our mouth can bind to the carbohydrates taken by our mouth, and convert them to the disaccharide, the maltose.
Here, in the above case the carbohydrate diet is the substrate, salivary Amylase is the enzyme and maltose is the product of the enzyme catalysed reaction.
