Low Hydrogen composition (basic/alkaline)

Question 25

pH levels always must be ______

Answer 25

Balanced

Question 26

Increasing enzyme concentration:

Answer 26

Increasing reaction rate

Question 27

Concentration of substrate is a limiting factor. As concentration increases:

Answer 27

The enzyme reaction rate increases

Question 28

What happens if the substrate concentration is high?

Answer 28

The enzyme comes saturated, and higher concentration of substrate does not increase reaction rate
