Core Question 3 1 point possible (graded) Check all the statements that are true: Enzymes can catlayze reactions that would never happen on their own. Enzymes are proteins. O The transition state is high energy The transition state is unstable. O Without an enzyme, very few molecules have enough energy to reach the transition state. The enzyme adds energy to the substrate so that it can reach the transition state During an enzyme-catalyzed reaction, no covalent bonds are broken or forTnerd. O During an enzyme-catalyzed reaction, no covalent bonds in the enzyme are broken or formed. When an enzyme-catalyzed reaction is complete, the enzyme is released unchanged

Explanation / Answer

1- enzyme are protein

2- trasnitionstate is high energy state

3- transition state is unstable

4-enzyme add up energy so that substrate reach the trasnition statae

5-when enzyme catalyzed the reaction is complete , the enzyme is relaesed unchanged.

Note- enzyme are catalyst which lower the activation energy of the reaction, thus forming transition sate followed by product formation , at the end enzyme is released unchanged.
