Acetobacter aceti converts alcohol to acetic acid according to the schiometric relation

In a vigorously agitated and aerated reactor containing 20 g/l ethanol, the organism produces 16g/l acetic acid and 2g/l was the residual ethanol concentration what are the theoretical and observed yields of acetic acid expressed in g/g ethanol

sap is translocated from areas of supply, called sources, to areas of metabolism or storage, called sinks. Which of the following statements about source and sink are TRUE?

a.) Sinks include any nonphotosynthetic organs of the plant and organs that do not produce enough photosynthetic products to support their own growth or storage needs

b.) Sources include exporting organs that are capable of producing photosynthate in excess of their own needs

c.) During the growing season of the first year, storage root is a sink, when it accumulates sugars received from the source leaves. During the second growing season the same root becomes a source

d.) Roots, tubers, developing fruits, and immature leaves, which must import carbohydrate for normal development, are all examples of sources tissues

Find the correct combination of the source and sink pattern of translocation.
