C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP)

Here's what each part represents:

* C6H12O6: Glucose, a simple sugar, is the primary fuel source.

* 6O2: Oxygen is required as an electron acceptor.

* 6CO2: Carbon dioxide is a waste product.

* 6H2O: Water is a waste product.

* Energy (ATP): Adenosine triphosphate is the energy currency of cells.

Explanation:

During cellular respiration, glucose is broken down in a series of steps. This process involves the transfer of electrons and the release of energy. The energy is used to create ATP, which cells use to power their functions.

Important Note: While this is the overall equation, cellular respiration is actually a complex process that occurs in several stages:

1. Glycolysis: Glucose is broken down into pyruvate. This occurs in the cytoplasm.

2. Krebs Cycle (Citric Acid Cycle): Pyruvate is further broken down, producing ATP and electron carriers. This occurs in the mitochondria.

3. Electron Transport Chain: Electrons are passed along a chain of molecules, releasing energy that is used to generate ATP. This also occurs in the mitochondria.
