NY Regents Enzymes

Enzymes may be referred to as the ​ (a)   .

Each chemical reaction uses a specific enzyme which ​ (b)   the rate of reaction.

The enzyme i​ (c)   changed during the reaction and can be reused.

Eventually after ​ (d)   the enzyme finally is destroyed.

Enzymes are named after the substrate that they act on, so which would be the enzymatic name for lipid?

• Lipase

• Lipose

• Lipid

All enzymes are either ​ (a)   or are proteins with non-protein parts known as ​ (b)   .

Often coenzymes are ​ (c)   .

Where the ​ (d)   attaches to the enzyme where the action occurs is called the active ​ (e)  

• proteins
• coenzymes
• vitamins
• site
• substrate

Enzymes with the non protein parts are called coenzymes, they are also known as:

• Vitamins

• Minerals

• carbohydrates

• lipids

The area where the substrates attaches to the enzyme is known as the

• active site

• coenzyme

• Vitamin

In the first stage of the Enzyme substrate complex :

1. 1. The enzyme forms a ​ (a)   with the substrate.

2. 2. The association between the enzyme and substrate is known as the " ​ (b)   ".

3. 3. Upon completion of the reaction, the enzyme and the ​ (c)   separate.

• temporary association
• Enzyme substrate complex
• products

Which has a lower activation energy?

• With enzyme

• Without enzyme

Which has a higher energy level

• reactants

• Products
