An enzyme is permanently changed by the reaction which it catalyzes. Select one: True False
An enzyme is permanently changed by the reaction which it catalyzes.
Select one:
True
False
Homework Answers
I believe the correct answer to be:
FALSE.
As the enzyme simply speed up the reaction by decreasing the activation energy required for the reaction to start. The enzyme does not officially take part in the reaction and hence remains unchanged at the end of the reaction.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

True or false? True False The function of the enzyme acyl CoA synthetase is the ATP-dependent coupling of fatty acids to CoA. True False Unsaturated fatty acids contain zero alkene bonds. True False The brain uses ketones instead of glucose for ATP production during long-term fasting. True False A biotin-deficient diet may lead to an increase of cytosolic acetyl CoA. True False Untreated, chronic ketone body production will raise blood pH levels. True False The availability of the metabolite malate determines whether acetyl CoA, made from...
