The respiratory quotient of the excess metabolism of exercise [PDF]

open access: yesProceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1929
Abstract In recent years much controversy has been aroused as to whether the body uses carbohydrate alone in order to provide energy for the recovery process from muscular exercise, or whether the other foodstuffs can be used directly for this purpose.

Drivers of the microbial metabolic quotient across global grasslands

open access: yesGlobal Ecology and Biogeography, 2023
AbstractAimThe microbial metabolic quotient (MMQ; mg CO2‐C/mg MBC/h), defined as the amount of microbial CO2 respired (MR; mg CO2‐C/kg soil/h) per unit of microbial biomass C (MBC; mg C/kg soil), is a key parameter for understanding the microbial regulation of the carbon (C) cycle, including soil C sequestration.

Metabolic Quotients of the Gravid Uterus of the Chronically Catheterized Guinea Pig [PDF]

open access: yesPediatric Research, 1985
The uptake of substrates by the pregnant uterus defines the "diet" of the uterus and conceptus. In order to determine the uterine substrate uptake, catheters were placed in the femoral artery and uterine veins of guinea pigs at 40-49 days gestation.

Leaf litter identity rather than diversity shapes microbial functions and microarthropod abundance in tropical montane rainforests

open access: yesEcology and Evolution, 2021
In tropical forest ecosystems leaf litter from a large variety of species enters the decomposer system, however, the impact of leaf litter diversity on the abundance and activity of soil organisms during decomposition is little known. We investigated the

Lipid Oxidation Assessed by Indirect Calorimetry Predicts Metabolic Syndrome and Type 2 Diabetes

open access: yesFrontiers in Endocrinology, 2019
Purpose: Diabetes has been linked to an impaired ability to oxidize fatty acids. Fat oxidation can be assessed clinically by a respiratory quotient measurement during fasting.

Soil microbial metabolism and invertase activity under crop rotation and no-tillage in North China

open access: yesPlant, Soil and Environment, 2013
Soil samples were collected at both jointing and maturing stages of maize and wheat to compare the effects of 4-year no-tillage (NT) and conventional tillage (CT) on seasonal variations of microbial biomass carbon (C), metabolic quotient, and invertase ...

Instability of Metabolic Quotients Obtained from Tissue Cultures.

open access: yesExperimental Biology and Medicine, 1960
SummaryMaximal growth of Earle's Strain L cells is obtained by using 15-20% horse serum with a medium containing 0.5% lactalbumin hydrolysate. Rate of lactate formation decreases as pH decreases but remains constant if the suspension is adequately buffered with bicarbonate.

Tree stratum alteration decreases C use efficiency and the stability of litter decomposition in a sacred fir (Abies religiosa) forest

open access: yesBotan‪ical Sciences, 2022
Background: There is limited information to predict the direction in which canopy modification affects the microbial carbon use efficiency (CUE) and, consequently, the magnitude and stability of litter decomposition in monodominant sacred fir (Abies ...
