Answer 1

An enzyme (select all that apply)

1) is not altered by reaction with a substrate (Y)

2) is changed by reaction with a substrateis (N)

3) made of carbohydrate (N). It is made of protein (amino acids/peptide/)

4) can be reused if not damaged (Y)

5) is made of protein (Y)

6) slows the rate of chemical reactions (N). It catalyze the chemical reactions

7) increases the rate of chemical reaction (Y)

Select all that apply. An enzyme

1) is a carbohydrate (N)

2) is a protein (Y)

3) is a biological catalyst (Y)

4) is changed by reaction with a substrate (N)

5) is not altered by reaction with a substrate (Y). It has active site where the functional groups bind reversibly.

6) can be reused if not damaged (Y)

7) increases the rate of chemical reaction (Y)

8) slows the rate of chemical reactions (N)

9) lowers the activation energy of a reaction (Y). This is how it acts as a catalyst.

10) increases the activation energy of a reaction (N)
