Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain cellular respiration by stage, location, yield, variants and relevance to health and ecology in general terms.

The set of metabolic processes by which cells convert nutrients into usable energy, mainly as ATP, including glycolysis, the citric acid cycle and oxidative phosphorylation in aerobic respiration, and anaerobic pathways such as fermentation and forms of energy metabolism in archaea such as methanogenesis.

What it is for: Biology education and research.

It can be explain the stages of respiration; compare aerobic and anaerobic pathways; estimate ATP yield; relate respiration to exercise, disease and ecosystems in general terms.

Distinguishing features

Produces ATP

Aerobic or anaerobic

Uses electron transport

Releases carbon dioxide in aerobic respiration

What it looks like

How it is recognised

Glycolysis, Krebs cycle and electron transport chain

Mitochondria in eukaryotes

Breathing is the separate process of ventilation
