Enzyme Kinetics Practice

A protein is made up of:

• long chain of amino acids

• bilayer of lipids

• long chain of nucleotides

• adenine, guanine, cytosine and uracil

This is a substance that can be added to increase the reaction:

• Catalyst

• Buffer

• Cofactor

• Temperature

What does NAD stands for:

• Nomenclature association disease

• Nucleotide amine deoxyde

• Nicotinamide adenine dinucleotide

• Adenosin triphosphate

Cu 2+ and enzyme is called:

• Prostetic group

• Metallic enzyme

• Co-enzyme

• Essential metal

Specific region on the enzyme's surface where the substrate molecule binds and undergoes a chemical reaction:

• Active site

• Allosteric site

• Binding site

• Regulatory site

What EC number for ligases?

• 1

• 6

• 3

• 4

In which type of inhibition does the inhibitor binds to the ES complex:

• uncompetitive

• competitive

• non competitive

• all of them

This is the name for the series of reactions that occur within cells of living organisms to sustain life

Competitive inhibitors bind to:

• Substrate

• Free enzyme

• ES complex

• Allosteric site

• Lineweaver-Burk

• Michaelis-Menten

• Dixon

• Arrhenius
