Biochem help - which of these substrates has the weakest binding?

Two questions:


An enzyme binds various substrates. Determine:

(A) substrate with the weakest binding

(B) substrate for which the enzyme has higher specificity

The question allows me to select multiple answers so I don't know if that means there are multiple answers.

i really hate multiple answers. you should knows its kcat/km from those calculations you can tell of thier affinity.
