Enzymes

Question 1

Logical cattle is that speed of the rate of the biochemical reaction

Answer 1

Enzymes

Question 2

Are biological molecules that act as catalyst in living organisms

Answer 2

Enzymes

Question 3

Is a substance that increases the rate of a chemical reaction without being consumed or permanently altered in the process

Answer 3

Catalyst

Question 4

Enzymes play closer role in values biological processes by facilitating and speeding of chemical reactions necessary for life

Answer 4

A fact

Question 5

Is the region that binds of straight cofactors and prosthetic groups and contains residue that helps to hold the substance

Answer 5

Active site

Question 6

Has a specific shape due to tertiary structure of protein
A change in the shape of protein affects the shape of active site and function of the enzyme

Answer 6

Active site a fact

Question 7

It chooses the substrate and binds to active site

Answer 7

Binding site

Question 8

It performs the catalytic action of enzyme

Answer 8

Catalytic site

Question 9

Enzymesbaccelerate chemical reactions by lowering the activation energy required for the reaction to occur this allows the productions to proceed more rapidly than they would without the enzyme

Answer 9

Catalysis

Question 10

Enzymes are highly specific interaction meaning each enzyme catalyze is particular reaction or a group of costly related reactions this specificity is often referred to as the lock and key model where the enzymes active site fits precisely with the substrate the molecule it acts upon

Answer 10

Specificity

Question 11

Enzymes are not consumed or changed during the reactions they catalyze after their action is complete enzymes are available to participate in further reactions

Answer 11

Reusability

Question 12

The activity of enzymes can be regulated to control the rate of metabolic processes this regulation ensures that chemical reactions occur at the appropriate rates and under the right conditions

Answer 12

Regulation

Question 13

Enzymes are generally proteins although some catalytic rna molecules called ribosomes also exhibit enzymes like activity

Answer 13

Protein nature

Question 14

It speeds of the reaction by lowering the activation energy required of the reaction represents does not affect the nature and properties of end product they are highly specific interaction that is each enzyme can be utilize one surround of substrate sensitive changes ph temperature substrate concentration involving a wide range of physiological processes including digestion energy production dna replication and many others

Answer 14

Characteristics of enzymes

Question 15

Without the enzyme is the vast majority of biochemical reactions essential for life food proceed too slowly to sustain the processes necessary for living organisms

Answer 15

What would happen to living things without the presence of enzyme

Question 16

Catalyzed oxidation reduction reactions involving the transfer of electrons between molecules

Answer 16

Oxidoreductases

Question 17

Facilitate the transfer of functional groups amino methyl or phosphate groups from one molecule to another

Answer 17

Transferases

Question 18

Catalyze the hydrolysis breakdown by water of various substrates example include lipases break down fats and proteases break down proteins

Answer 18

Hydrolases

Question 19

Catalyze the removal of groups from one substrates without hydrolysis they make cleave or form bonds

Answer 19

Lyases

Question 20

Capitalize the rearrangement of atoms within a molecule converting it from one isomer to another

Answer 20

Isomerases

Question 21

Also known as synthetases these enzymes facilitate the joining of two molecules often coupled with the hydrolysis of atp

Answer 21

Ligases

Question 22

Are typically composed of two main components the protein moity and the cofactor or coenzyme

Answer 22

Enzymes

Question 23

Protein moiety

Answer 23

•amino acid
• three dimensional structure
• active site

Question 24

Enzymes or proteins and their primary structure consists of a liner chain of amino acids the sequence of this amino acids is specific to each enzyme and determines its unique three dimensional structure and function

Answer 24

Amino acid

Question 25

The linear amino acid chain folds into a complex three dimensional structure this structure is crucial for the enzymes catalytic activity as the active site the region where the substrate binds and the catalytes occurs is typically a specific pocket or cleft within this structure

Answer 25

3D structure

Question 26

The active site is the region where the enzymes interacts with its substrate is often as a pacific shape and chemical properties that allows it to bind to the substrate with high specificity

Answer 26

Active site

Question 27

Some enzymes require non protein molecules known as cofactors to be fully functional cofactors can be metal ions zinc iron magnesium or small organic molecules

Answer 27

Cofactors

Question 28

Coenzymes are organic molecules that function as the cofactors they are often derived from vitamins and assist the enzyme in catalyzing reactions

Answer 28

Coenzyme

Question 29

The combination of protein and coenzyme/cofactors

Answer 29

Holoenzyme

Question 30

The cofactor is absent

Answer 30

Apoenzyme

Question 31

Breaks down carbohydrates starch into sugars in the mouth and small intestine

Answer 31

Amylase

Question 32

Capitalize the breakdown of lipids fats into fatty acids and glycerol in the small intestine

Answer 32

Lipase

Question 33

Digest proteins into amino acids in the stomach and small intestine

Answer 33

Protease

Question 34

Enzymes involved in blood clotting such as thrombin and factor x

Answer 34

Coagulation factors

Question 35

Breaks down neurotransmitter like serotonin and dopamine

Answer 35

Monoamine oxidase

Question 36

Breaks down bacterial cell walls contributing to the immune response

Answer 36

Lysozyme

Question 37

Involved in the regulation of blood pressure and fluid balance

Answer 37

Renin

Question 38

Are release and the enzyme is free to bind other substrate

Answer 38
