What is the term for a protein that acts as a catalyst in biochemical reactions?

Enzyme 

100

This class of enzymes catalyzes oxidation-reduction reactions.

Oxidoreductases

100

Enzyme activity reaches a maximum rate at this specific condition before it declines due to enzyme denaturation.

optimum temperature

100

This type of vitamin is stored in fat deposits and includes vitamins A, D, E, and K.

fat soluble vitamins 

200

This term describes the site on an enzyme where a substrate binds.

active site

200

Enzymes that transfer a group from one molecule to another are called this.

transferases

200

True or False: Increasing the enzyme concentration will always increase the reaction rate indefinitely.

false

200

his vitamin, also known as ascorbic acid, is an antioxidant found in fruits and vegetables.

vitamin c

300

Enzymes are typically water-soluble globular proteins. True or false?

True 

300

Lipases, proteases, and amylases are subclasses of which enzyme class?

hydrolases 

300

When all active sites of an enzyme are occupied, the enzyme is considered to be at this point.

saturation

300

These vitamins must be obtained through diet as they are essential for health and cannot be synthesized by the body.

vitamins 

400

Enzyme specificity is limited to specific substrates or types of reactions. This enzyme, for example, specifically decomposes hydrogen peroxide.

Catalase

400

Enzymes that rearrange the atoms within a single molecule to form an isomer belong to this class.

isomerases 

400

Most enzymes show maximum activity within this pH range.

5-9

400

This type of vitamin dissolves in water and includes the B vitamins and vitamin C.

water soluble vitamins 

500

The number of substrate molecules processed by one enzyme molecule per unit time is known as this.

turnover number

500

Which class of enzymes catalyzes the bonding of two molecules, often requiring ATP?

Ligases

500

When this factor is increased, the reaction rate increases, provided there’s enough substrate available.

Enzyme concentration 

500

These are micronutrients that are needed in amounts greater than 100 mg per day, including calcium and magnesium.
