Why do you turn biological reactions into equations at all?
Your body is running thousands of chemical changes right now, and writing each one out in full sentences would be a mess. When you turn a reaction into an equation, you shrink a complicated process into something you can read fast, compare easily, and check for mistakes.
Scientists use equations because you need a format that is short, exact, and understood everywhere. If one biologist in one country writes a reaction and another reads it somewhere else, they should both understand the same thing and be able to repeat the same work.
When scientists write a reaction as an equation, they are showing the substances that go in and the substances that come out in a standard scientific form.
Real reactions inside you usually happen through lots of tiny stages, often with enzymes helping at each step. An equation ignores those hidden details and keeps only the overall change, which is usually the part you need for analysis.
Analogy: Think of it like a food delivery app showing only “picked up” and “delivered.” You do not see every traffic light, turn, or delay, but you still understand the journey.
