Assume Saccharomyces cerevisiae is grown in a nutrient medium containing the radioisotope ³²P. After 48 hr incubation, the ³²P would most likely be found in the S. cerevisiae's

Question

Quizplus · Accepted Answer

The radioisotope ³²P represents sulfur-32 (32S), which is commonly incorporated into amino acids such as cysteine and methionine. These amino acids are then used in the synthesis of proteins. Given that the plasma membrane contains various proteins, including those with sulfhydryl groups, sulfur-32 would most likely be found in the plasma membrane of Saccharomyces cerevisiae after incorporation into membrane proteins.
