In living organisms, when nutrients are broken down to produce energy, this is the volume ratio of carbon dioxide emitted over a certain period of time to oxygen inhaled, CO 2 /O 2. This is commonly abbreviated as RQ and is also called the respiratory rate or respiratory coefficient. This value varies depending on the type of nutrients ingested. For example, in the complete combustion of carbohydrates, glucose is broken down into C 6 H 12 O 6 + 6O 2 [Nobuyoshi Irie] Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
生体において、栄養素が分解されてエネルギーを産生する際に、一定時間に排出された炭酸ガスと吸入した酸素の体積比CO2/O2のことで、一般にはRQと略称し、呼吸率、呼吸係数ともいう。この値は摂取する栄養素の種類によって異なり、たとえば炭水化物の完全燃焼では、ブドウ糖が [入江伸吉] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
