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.
 
        
        
        
<span>Intrinsic factor is a glycoprotein principally secreted by the parietal cells of the stomach. This secretion is needed to produce mature erythrocytes. Its secretion is governed by the same biochemical processes that regulate acid secretion and its action is to assist in the absorption of vitamin B12.</span>
        
             
        
        
        
Answer:
Genetic resistance (or genetic tolerance) refers to the ability of certain organisms to endure environmental conditions that are extremely stressful or lethal to non-adapted individuals of the same species

A mold was developing in some of the culture dishes used by Sir Alexander Fleming and was eliminating some of the bacterial population. The hypothesis is that the mold was generating a chemical, which was toxic to the bacteria in the dishes and killed them.
The hypothesis was examined by separating the Penicillium and administering it into the solution of nutrient broth. After the growth of Penicillium it was withdrawn from the broth. The broth was then eventually supplemented to the bacteria and the bacteria died. Thus, it can be concluded that the hypothesis is supported.
