B1.2 - Enzymes Flashcards
What is an enzyme?
An enzyme is a biological catalyst
What is a substrate
An molecule that binds to an enzyme
What is an active site
When an enzyme binds to a substance during a reaction.
Three factors that affect speed of reaction?
Temperature, PH levels and concentration gradient.
When the substance is inside the active site, it is called…
Enzyme substrate complex
How can enzymes speed up reaction?
Building larger molecules from small molecules or breaking larger molecules into smaller molecules.
What is DNA?
DNA is a genetic material
What is the difference between a monomer and a polymer
A monomer only has one molecule, a polymer has many molecules.
Is DNA a polymer?
Yes, DNA is a polymer.
What is a structure of the DNA called?
A double helix
Complementary Bases of DNA are.
A-T
G-C
Process of transcription
It unzips the strands.
MRNA is produced in the process of transcription
Occurs in the nucleus
Process by which MRNA is used to make protein?
Translation
What is a nucleotide?
Unit of DNA made of phosphate group, deoxyribose and base.
DNA is a polymer made up of monomers called:
Nucleotides
