Answer:
Comma goes before "and"
Explanation:
This is another instance where we use a coordinating comma.
We see the word "and", and we immediately think of the coordinating conjunctions FANBOYS (For, And, Nor, But, Or, Yet, and So). We always put a comma before a coordinating conjunction.
Since there's the word "and", we want to put the comma before the "and" and after the "protein".
Hope this helps!
