This method of respiration, while complicated, is highly efficient.
Respiration is often seen as the opposite of photosynthesis, because some reactants of photosynthesis, namely carbon dioxide and water, are the products of respiration, while oxygen, a reactant of respiration, is a product of photosynthesis.
Although Ca2+ activated both respiration and heat production, the enhancement of respiration was ∼30%, while activation of heat production was ∼60%.
We demonstrated that forced expression of p70S6K stimulated mitochondrial respiration while knockdown of p70S6K suppressed mitochondrial respiration.
Data include measurements of the impact of ZnO nanoparticles on body burden, feeding, respiration, shell length, biomass, and mortality of mussels kept in laboratory tanks for over 100 days.
When lower concentrations of succinate are used, approx. 0.4 0.8% of respiration produces H2O2 [ 57], while use of the physiological substrate palmitoyl-CoA decreases H2O2 production to approx. 0.15% of respiration [ 24], and, when glutamate/malate are used as substrates, H2O2 production accounts for approx. 0.12% of respiration [ 27].
"Everything is a balance, in terms of trying to improve the function of one system, like respiration, while not injuring another, like the brain," Camilia Martin told me.
Notably, purified mitochondria from Wt MEFs showed release of cytochrome c with ionomycin stimulation and loss of respiration with serial addition of Ca2+, while mitochondria lacking Bax and Bak protein did not show cytochrome c release or loss of respiration.
As a result, zoo plankton biomass increased while O2 concentrations decreased, apparently mediated by unfavorable ratios of respiration and primary production.
Sasa switched from net sinks to sources of CO2 while the forest canopy was closed, with increased rates of respiration and decreased rates of photosynthesis.
