C. GDP is phosphorylated to produce GTP</span>
Substrate level phosphorylation occurred in
kreb cycle inform of metabolic reaction that involve the transfer of phosphoryl
group to GDP or ADP from another phosphorylated compound which result into
formation of GTP or ATP. This process commonly occurs in the cytoplasm of cells
during glycolysis and also in the mitochondria during krebs cycle.
Answer:
1.) stromatolites
2.) photosynthesis
3.) Ordovician
4.) Cambrian
5.) oxygen
6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.
7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.
Explanation:
From Penn
Scientific validity is the applicability of a conclusion drawn in the context of a scientific experiment to the world at large.
