What is the optimum ph for catalase activity? a) 3.0 b) 7.0 c) 10.0 d) 13.0

Catalase is a common enzyme very important in reproductive reactions and is found in almost all living organisms exposed to oxygen.   There are different catalase activities,  pH optimum of which between 4 and 11 depending on the species. However, the optimum pH for human catalase is approximately 7.0 (letter C). 

the answer is false?

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
