How does a change in pH above or below optimal pH affect enzyme
function?

A. No change
B. Reaction happens faster
C. Enzyme dies
D. Enzyme denatures

Answers

Answer:

[tex]\boxed {\tt D. \ Enzyme \ denatures}[/tex]

Explanation:

Extreme temperatures or pH can denature enzymes.

Enzymes have a very special and specific shape that determines which substrate they can act on. If the pH changes too dramatically, then the peptide bonds holding the amino acids of the enzyme together break.

When the bonds break, the enzyme loses its shape and it cannot function anymore.

So, there is a change, the reaction doesn't happen faster or die. We can eliminate choices A, B, and C. The correct choice is D. enzyme denatures

If 5x+4y=58 and 3x + 7y = 67 find the value of ( x + y ) ​

Answers

Explanation:

5x + 4y = 58 ....1

3x + 7y = 67 ....2

....1 × 3 both sides of the equation

15x + 12y = 174 ....3

....2 × 5 both sides of the equation

15x + 35y = 335 ....4

.....4 - ......3 both sides of the equation

35y - 12y = 335 - 174

23y = 161

y = 161/23
