Homework Answers
I believe the correct answer to be:
Option E) ATP can transfer the phosphoryl group to phosphoenolpyruvate.
because as seen below in the structure of phosphoenolpyruvate, it is already phosphorulated.
feel free to leave a comment down below for any further query. good rating would be appretiated if you find my answer helpful. thank you.
