What is the name given to the final stage of cellular respiration?GlycolysisADPThe Electron Transport Chain

The correct name given to the final stage of cellular respiration is The Electron Transport Chain.

Explanation

Cellular respiration is a metabolic process that converts glucose into energy in the form of adenosine triphosphate (ATP). It consists of several stages: glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain.

1. Glycolysis is the first step, occurring in the cytoplasm, where one glucose molecule is broken down into two molecules of pyruvate, yielding a small amount of ATP and NADH.

2. The Krebs cycle follows, taking place in the mitochondria, where the pyruvate is further broken down, and more NADH and FADH2 are produced along with some ATP.

3. Finally, the Electron Transport Chain (ETC) is the last stage that occurs in the inner mitochondrial membrane. Here, the high-energy electrons from NADH and FADH2 are transferred through a series of protein complexes, leading to a proton gradient used to produce a significant amount of ATP via chemiosmosis.

In summary, while glycolysis and ADP are important components of cellular respiration, the final stage where the majority of ATP is produced is known as the Electron Transport Chain.
