Q:

What is the chemical equation for cellular respiration?

A:

Quick Answer

Cellular respiration is represented by the chemical formula C6H12 + 6O2 = 6CO2 + 6H2O + energy (as ATP). Written in word form, the formula is "glucose + oxygen = carbon dioxide + energy (as ATP)". "ATP" stands for "adenosine triphosphate," a nucleotide that stores and transmits energy.

Full Answer

Cellular respiration refers to the reactions within a cell that help produce ATP using energy stored as glucose. There are two types of cellular respiration: aerobic, which requires oxygen, and anaerobic, which does not require oxygen. In aerobic respiration, glucose is completely broken down into carbon dioxide and water. This process is represented by the chemical formula C6H12O6 + 6O2 = 6CO2 + 6H2O + 36 or 38 ATP. Anaerobic respiration, also known as fermentation, produces alcohol in plants and fungal cells. It also makes lactic acid in animal cells. The anaerobic process is represented by the formula C6H12O6 = 2CO2 + 2C2H5OH + 2 ATP.

The energy that is produced in cellular respiration is in the form of ATP, which is fundamental for all processes of life. There are four components of cellular respiration. They are glycolysis, transition reaction, Krebs cycle and electron transport chain. This entire process occurs partially in the cytoplasm and partially in the mitochondria.
