To determine the correct formula for cellular respiration, we need to understand the process and the reactants involved. Cellular respiration is the metabolic process by which cells break down organic molecules, such as glucose, to produce energy in the form of adenosine triphosphate (ATP).
The correct formula for cellular respiration is:
Glucose + oxygen → carbon dioxide + water + ATP
In this reaction, glucose and oxygen are the reactants that combine during respiration. Through a series of biochemical reactions, glucose is oxidized, and oxygen is reduced to produce carbon dioxide, water, and ATP.
Hence, the correct formula for cellular respiration is Glucose + oxygen → carbon dioxide + water + ATP.
