Question
Chapter 15, Problem 21E
Summary Introduction
To explain: The length of the products of the transketolase reaction when both substrates are five-carbon sugars.
Concept introduction: The alternative pathway of glucose oxidation is pentose phosphate pathway, which includes 2 phases: oxidative phase and non-oxidative phase. The principal products of the pentose phosphate pathway are ribose-5-phosphate and NADPH. At stage 3 of pentose phosphate pathway, carbon–carbon bond cleavage and formation occur, and it is catalyzed by transaldolase and transketolase.

She then carries out the same experiment using ATP labeled with 32P in the central position, [ẞ-³2P]ATP, but the 32P does not appear in P; within such a short time. Which statements explain these results? Yeast cells reincorporate P; released from [ß-³2P]ATP into ATP more quickly than P¡ released from [y-³2P]ATP. Only the terminal (y) phosphorous atom acts as an electrophilic target for nucleophilic attack. The terminal (y) phosphoryl group undergoes a more rapid turnover than the central (B) phosphate group.
