Question
Chapter 2, Problem 32RQ
Summary Introduction
To review:
The participation of lysosomes in the life of a cell.
Introduction:
Membrane-bound organelles found in the cytoplasm of eukaryotic cells (both plants and animals), which contain digestive juices, are known as lysosomes. These are also referred to as suicidal bags as they are vesicles, which contain granules filled with digestive enzymes, and contribute to cell autophagy in case of infection.

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.
