What is the difference between a synthesis reaction and a digestion reaction?

Explanation:

Synthesis reactions occur when two different atoms or molecules interact to form a different molecule or compound

Digestion reaction is when its  broken down into glucose by a type of chemical reaction called hydrolysis

your answer is "the 1950's"
