If you are wondering why we consider ourselves to be carbon-based organisms - check out the Krebs cycle, the basis of energy production in every cell in our bodies. Carbon is extremely versatile at linking together diverse elements – able to form more compounds than any other element we have...
What is the primary function of the Calvin cycle? What is the other name for Krebs cycle? Name two organic molecules that can provide cells with energy. How does carbon dioxide get into a plant cell? Describe the role of carbon in biological systems. ...
of an aspect of an ecologicalcyclein which a required element flows through different types of organisms as it changes itsoxidation statefrom CO2to (CH2O)nand back to CO2. Metabolic cycles in general—the extraction by organisms of useful energy and food molecules from environmental source material...
[3]. In addition, CO also inhibits the intercellular O2-transfer, which results in O2molecules remaining in the blood stream not reaching the intracellular space for cellular respiration[4]. Furthermore, CO inhibits the Krebs-Cycle through inhibition of cytochrom-c-oxydases and thus reduces the...
Analysis of bacterial transcripts revealed a restoration of microbial functional activity, with partial or full recovery of the Krebs cycle, β-oxidation, respiratory chain and glycolysis. Mice treated with CORM-401 exhibited normalization of several plasma and fecal metabolites that were disrupted by ...
Energy metabolism and carbon flow in Cryptosporidium parvum lacks a Krebs cycle in the remnant mitochondria, thus probably solely relies on glycolysis to generate energy. The glycolytic pathway in this parasite consists of enzymes with a complex evolutionary history and diverse phylogenetic affin... G...

Complex molecules are made up of carbon bonded with other elements, especially oxygen, hydrogen and nitrogen, and carbon is able to bond with all of these because of its four valence electrons. It is often assumed in astrobiology that if life exists somewhere else in in the universe, it ...
A combination of the above two mentioned electron transfer processed affords the three-membered metallacycle complex IV. Moreover, the side-on-bonding p-complex V can also be formed in a similar spatial arrangement of atoms through the coordination of the C-O double bond to the central metal...
Cellulose synthase plays a major role in BNC synthesis, acting in concert with other enzymes and regulatory proteins. The process involves several metabolic pathways such as the phosphogluconate pathway and the Krebs cycle. These pathways involve four key steps including the conversion of glucose to ...
