Topic 3a: Enzyme function

ΔG‡ means 'free energy of activation'

• Yes

• No

Enzyme makes the formation of product faster by increasing the reaction's activation energy

• Yes

• No

The barrier to transform from the substrate to product is smaller by the action of an enzyme

• Yes

• No

Enzyme is not used up after an enzymatic reaction

• Yes

• No

Enzyme-U converts compound-S to compound-P. After several cycles of enzymatic reaction, the yield (production, or formation) of compound-P is slower and eventually stop. Why is that so? You can select multiple answers.

• Enzyme-U is used up after several round of reaction

• Enzyme-U starts to denature

• Compound-P inhibits the reaction

• Compound-S is not a suitable substrate for Enzyme-U
