Worked Solution & Example Answer:Enzymes are used in many processes in both plants and animals - Leaving Cert Biology - Question c - 2011
Step 1
What is an enzyme?
Answer
An enzyme is a biological catalyst that accelerates chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. Enzymes are typically proteins made up of long chains of amino acids and are specific to particular substrates.
Step 2
Step 3
Name any two factors that can affect enzyme activity.
Answer
Two factors that can affect enzyme activity include temperature and pH level. Enzymes generally have optimal temperature and pH ranges where they function best, and deviations from these conditions can lead to decreased activity or denaturation.
Step 4
What is meant by the term immobilised in relation to enzymes?
Answer
Immobilised enzymes are enzymes that are attached to an inert, insoluble material, which prevents them from mixing freely with the substrates. This allows for the enzymes to be used repeatedly in industrial processes while making it easy to separate them from the products.
