Q

What is the function of a Substrate?

A

The substance and Enzyme acts/binds on to

17
Q

What is the name of the area to which the Substrate binds on to the Enzyme?

A

Active Site

18
Q

After a reaction occurs, what is released?

A

A product(s)

19
Q

What can Enzyme activity be affected by?

A

Temperture, pH (how acidic or basic), Ionic Concentration, Inhibitors

20
Q

Temperature?

A

Increasing (hot) temperatures generally speeds up a reaction and decreasing (cold) temperatures slows down a reaction. However, extreme (too high) temperatures can cause an Enzyme to denature (lose its shape) and stop working

21
Q

pH?

A

Enzyme activity is at its maximum value at the optimum pH. As the value is increased above or decreased below the optimum pH the Enzyme activity decreases

22
Q

What does the word OPTIMAL mean?

A

Best

23
Q

How does a competitive inhibitor affect Enzyme activity?

A

If the active site is blocked the substrate can’t bind

24
Q

What happens to an Enzyme when a non-competitive inhibitor attaches to it?

A

Changes Substrate shape
