Enzymatic Reactions

Enzymatic Reactions is when special proteins in food or your body speed up changes, like breaking down vitamin C in orange juice.

Think of it this way

A key fits into a lock to open a door. Enzymes work the same way — each one has a shape that fits only one type of molecule. In your orange juice, enzymes latch onto vitamin C and break it into smaller pieces. Without the right enzyme, the reaction slows to a stop.

Explaining enzymatic reactions by grade level

Your body has tiny helpers that break food apart. When you drink orange juice, these helpers grab the vitamin C and pull it into small pieces your body can use. Without them, it would take too long. Each helper works on just one job, like a key that fits one lock.

Cat Food Digestibility by Brand

Special proteins speed up the chemical reactions that break down food — and that same process is at work in this project. You simulate a cat's digestive system using hydrochloric acid and meat tenderizer, where the tenderizer contains enzymes similar to those in a cat's small intestine. Four brands — IAMS, Friskies, Pet Promise, and Nutro Natural Dry — each soak first in acid at pH 2, then in the tenderizer solution. After drying, you weigh what remains and calculate the percentage digested, comparing how effectively each brand's nutrients become available through enzymatic digestion.
