Enzyme basics
What is the term for a protein that acts as a catalyst in biochemical reactions?
Enzyme
This class of enzymes catalyzes oxidation-reduction reactions.
Oxidoreductases
Enzyme activity reaches a maximum rate at this specific condition before it declines due to enzyme denaturation.
optimum temperature
This type of vitamin is stored in fat deposits and includes vitamins A, D, E, and K.
fat soluble vitamins
This term describes the site on an enzyme where a substrate binds.
active site
Enzymes that transfer a group from one molecule to another are called this.
transferases
True or False: Increasing the enzyme concentration will always increase the reaction rate indefinitely.
false
his vitamin, also known as ascorbic acid, is an antioxidant found in fruits and vegetables.
vitamin c
Enzymes are typically water-soluble globular proteins. True or false?
True
Lipases, proteases, and amylases are subclasses of which enzyme class?
hydrolases
When all active sites of an enzyme are occupied, the enzyme is considered to be at this point.
saturation
These vitamins must be obtained through diet as they are essential for health and cannot be synthesized by the body.
vitamins
Enzyme specificity is limited to specific substrates or types of reactions. This enzyme, for example, specifically decomposes hydrogen peroxide.
Catalase
Enzymes that rearrange the atoms within a single molecule to form an isomer belong to this class.
isomerases
Most enzymes show maximum activity within this pH range.
5-9
This type of vitamin dissolves in water and includes the B vitamins and vitamin C.
water soluble vitamins
The number of substrate molecules processed by one enzyme molecule per unit time is known as this.
turnover number
Which class of enzymes catalyzes the bonding of two molecules, often requiring ATP?
Ligases
When this factor is increased, the reaction rate increases, provided there’s enough substrate available.
Enzyme concentration
These are micronutrients that are needed in amounts greater than 100 mg per day, including calcium and magnesium.
