Hi

Hi. Feedback for this article can go here. Sbharris 23:59, 25 April 2006 (UTC)[reply]

I found some point of concern. The article said that "When cellular respiration breaks down carbon-containing molecules to release energy, carbon dioxide is released as a byproduct. Carbon dioxide contains two oxygen atoms and only one carbon atom, but food molecules such as carbohydrates do not contain enough oxygen to provide both oxygen atoms found in CO2. It turns out, one of the two oxygen atoms in CO2 is derived from body water. If the oxygen in water is labeled with 18O, then CO2 produced by respiration will contain labeled oxygen" but I thinks in carbohydrate metabolism no needs oxygen atoms that it is derived from water. First, we still need O2 for breathing and when O2 supply is not enough, the anaerobic respitaration will be occurred. Second, I couldn't found which enzyme or metabolic pathway in human body that can seperate H2O into H2 and O2. Anyome have an evidence to support this argument. — Preceding unsigned comment added by 171.96.182.136 (talk) 11:52, 6 July 2016 (UTC)[reply]

I agree, this didn't seem to make any sense and I couldn't find any references to support the way they explained it. Have changed the text and added a reference Zchahe7 (talk) 02:09, 24 July 2024 (UTC)[reply]

Doubly-labeled water → Doubly labeled water — to conform to WP:HYPHEN, which states "A hyphen is not used after a standard -ly adverb (a newly available home, a wholly owned subsidiary) unless part of a larger compound (a slowly-but-surely strategy)". The phrase is used without the hyphen by NIH, AJCN and other external sources. Chris the speller ^yack 18:23, 15 April 2011 (UTC)[reply]

Support: Nominator is correct. I wonder if this can still be converted to an uncontroversial request... –CWenger (talk) 22:58, 15 April 2011 (UTC)[reply]

Measurement clarity, please.

From this article I was unable to tell for sure

1. exactly what do you measure, and

2. How do you measure it.
