Question 1

Enzyme

Answer 1

Speeds up rate of a specific chemical reaction in the cell, used over and over, almost always a protien

Question 2

Substrate

Answer 2

The substance which the enzyme act upon

Question 3

Active site

Answer 3

Region on enzyme where substrate binds and chemical reaction happens

Question 4

Activation energy

Answer 4

minimum energy required for a reaction to happen

Question 5

1st property of an enzyme

Answer 5

Sensitive to heat, temp, PH

Question 6

2nd property of an enzyme

Answer 6

Not consumed in reaction

Question 7

3rd property of an enzyme

Answer 7

Almost always a protein

Question 8

4th property of an enzyme

Answer 8

Reaction specific

Question 9

How would you maximize enzyme activity?

Answer 9

Temp, PH, enzyme concentration, substrate concentration, inhibitors or activators

Question 10

Compare and contrast inhibition and activation of enzymes

Answer 10

Molecules that increase the activity of an enzyme are called activators, while molecules that decrease the activity of an enzyme are called inhibitors.

Question 11

Relationship between reaction rate and substrate concentration

Answer 11

Increasing substrate concentration also increases the rate of reaction to a certain point

Answer 12

As you increase the concentration of the coenzyme, the rate of the enzyme reaction tends to increase proportionally.
