<span>D is the correct answer. Metabolism is formed of two processes, anabolism, which builds new structures, for example, proteins, and catabolism, which breaks down existing structures. Catabolism breaks down large molecules like lipids into smaller ones like fatty acids.</span>
Klinglers iron agar medium is used to find the enterobacteria which can ferment glucose , lactose and hydrogen Sulphide . They are H₂S producing bacteria .
This media have phenol red as an indicator. When the glucose is fermented to acid , the production of acid turn the indicator from red to yellow, but it is then reoxidised and turns red again . When lactose is fermented it produce large amount of acid , and turn indicator yellow . Hence the slant will become yellow.And combination of ferrous sulphate and sodium thiosulphate helps in detection of H₂S which produce black color at the butt .
