Cellular respiration refers to the series of biochemical processes involved in the production of ATP molecules. The three steps of cellular respiration are glycolysis, the Krebs cycle and the electron transport chain.
Cellular respiration consists of three parts: glycolysis, the citric acid cycle (kreb's cycle), and the election transport chain. The only part that requires oxygen is the electron transport chain, because oxygen is the final electron acceptor.
The major purpose of respiration is the exchange of gases. In humans, oxygen is taken in for use in the body while carbon dioxide is eliminated. Cellular respiration serves the function of creating energy for the organism.
Glucose is a reactant of the aerobic stages of cellular respiration because in the process of glycolysis, which is one of the stages of cellular respiration, glucose is split into two three- carbon molecules.
There are about three main stages of cellular respiration 1) Glycolysis 2) Krebs cycle 3) Electron Transport Chain (E.T.C) The goal of cellular respiration is to release energy for performing various vital functions.
