Answer 2

Enzymology

Question 3

Function of Enzymes: (6)

Answer 3

1. Hydration of Carbon Dioxide (respiration)
2. Nerve induction
3. Muscle contraction
4. Nutrient degradation (digestion)
5. Growth & Reproduction
6. Energy storage and use

Question 4

Component of enzyme: (2)

Answer 4

1. Active site
2. Allosteric site

Question 5

Component of enzyme:

This is a cavity of an enzyme where substrates bind and undergo a chemical reaction; substrate must fit into this site

Answer 5

Active site

Question 6

Component of enzyme:

Cavity other than the active site that binds regulatory or effector molecule

Answer 6

Allosteric site

Question 7

Terms associated with enzymes: (2)

Answer 7

1. Substrate
2. Cofactors

Question 8

Terms associated with enzymes:

This is the substance acted upon by enzymes; specific for a particular enzyme

Answer 8

Substrate

Question 9

Why is enzyme remains unchanged during an enzymatic activity?

Answer 9

because enzyme is not part of the biochemical reaction it is only present to
accelerate or speed up the reaction process

Question 10

This would promote the conversion of substrate into a product or different
form

Answer 10

Enzymatic Activity

Question 11

Terms associated with enzymes:

These are non-proteins entities or substances added in the enzyme substrate complex to manifest the enzyme activity; to enhance enzymatic reaction

Answer 11

Cofactors

Question 12

Cofactors: (5)

Answer 12

1. Coenzyme
2. Activator
3. Isoenzyme
4. Apoenzyme
5. Holoenzyme

Question 13

Cofactor that is also known as second substrate; organic cofactor that hasten enzymatic reaction

Answer 13

Coenzyme

Question 14

Cofactor that is either metallic or non-metallic ion that is added to enhance enzymatic activity

Answer 14

Activator

Question 15

Cofactor enzymes with similar enzymatic activity but differ in their physical, biochemical & immunologic characteristics

Answer 15

Isoenzyme

Question 16

protein portion of enzyme; if subjected to denaturation, enzymatic activity is lost

Answer 16

Apoenzyme

Question 17

Temperature where denaturation is promoted

Answer 17

56°C

Question 18

Which proteins are destroyed at 56°C?

Answer 18

Tertiary protein

Question 19

active substance formed by the combination of a coenzyme and apoenzyme

Answer 19

Holoenzyme

Question 20

This term is used for coenzyme if the coenzyme is tightly bound to the apoenzyme

Answer 20

Prosthetic group
