The role of enzymes Flashcards
Why are enzymes necessary in plants and animals
To control metabolic reactions
Define enzymes
Enzymes are proteins that speed up a reaction without being used up in the reaction
Define substrate
The substrate is the substance with which an enzyme reacts
Define product
The product is the substance(s) the enzyme forms
Name some catabolic enzymes
Amylase, digestive enzymes like pepsin and lipase, and enzymes used in respiration
What type of enzyme is amylase?
a catabolic enzyme
What is amylase used with, in terms of substrates and what is its product?
Amylase is an enzyme that converts starch into maltose
What is amylase also known as?
Diastase
How is amylase a catabolic enzyme?
It breaks down a substance into simpler parts
Give an example of the enzyme amylase being used in a plant
When seeds germinate, amylase converts starch in the seed into maltose
Give examples of anabolic enzymes in plants and animals.
How are they anabolic enzymes?
The enzyme DNA ligase is used in genetic engineering to join two pieces of DNA together.
DNA polymerase is an enzyme found in both plants and animals and forms and repairs DNA.
They convert simpler molecules into a more complex form
How are enzymes that control photosynthesis anabolic enzymes?
They convert water and carbon dioxide into glucose
