These data suggest that aerobic and anaerobic respiration are interlinked.
In support of our hypothesis we observed that many genes involved in anaerobic respiration, especially denitrification, were up-regulated in mature biofilms.
For instance, compared to invertebrates, vertebrates have evolved a metabolism that places greater reliance on the quick mobilization of energy through anaerobic respiration.
After fertilization in mammalian embryos, measurements of the relative levels of aerobic and anaerobic respiration suggest that both pathways are active during preimplantation embryo development.
These data suggest that anaerobic respiration can support preimplantation embryo development, at least in the mouse.
As demonstrated in the figures, lactic acid, present in the external medium, enters the oocyte and is also produced by anaerobic respiration in the oocyte cytoplasm.
Because this cannot be replaced by sufficient oxidative phosphorylation, the rundown of both aerobic and anaerobic respiration results, leading to insufficient energy production, and causing the degeneration in embryo development.
To gain further insight into this aspect, we analyzed the expression profiles of a number of genes known to be involved in anaerobic respiration in more detail.
