FACTORS THAT AFFECT ENZYME ACTIVITY

Question 1

is a measure of the rate at which an enzyme converts substrate to products in a biochemical reaction

Answer 1

Enzyme activity

Question 2

List all the four factors affect enzyme activity.

Answer 2

Temperature, Ph, Substrate concentration, and enzyme concentration.

Question 3

is the temperature at which an
enzyme exhibits maximum activity.

Answer 3

Optimum temperature

Question 4

cause disruptions in the tertiary structure of the enzyme; denaturation is occurring.

Answer 4

Temperature

Question 5

is the pH at which an enzyme exhibits maximum activity

Answer 5

Optimum pH

Question 6

When the concentration of an enzyme is kept constant

Answer 6

Substrate Concentration

Question 7

is a bacterium
that can function in the highly acidic environment of the stomach

Answer 7

Helicobacter pylori

Question 8

is the number of substrate molecules transformed per minute by one
molecule of enzyme under optimum conditions of temperature, pH, and saturation.

Answer 8

turnover number

Question 9

“browning reaction”

Answer 9

phenolase (or polyphenoloxidase),

Question 10

Maximum enzymatic activity is
possible only within a narrow
pH range; outside this pH
range, the protein is denatured
and activity drops sharply.

Answer 10

PH

Question 11

substrate concentration until
full saturation occurs; then
the rate levels off.
Reaction rate increases with
increasing enzyme
concentration, assuming
enzyme concentration is much
lower than that of substrate

Answer 11

Concentration
of Enzyme
