If a Cell is Starved for ATP,which of the Following

Question

If a cell is starved for ATP,which of the following pathways would most likely be shut down?
A)Krebs cycle
B)glycolysis
C)pentose phosphate pathway
D)Krebs cycle and glycolysis

Accepted Answer

The pentose phosphate pathway is primarily involved in the production of NADPH and ribose-5-phosphate rather than ATP. If a cell is starved for ATP, it would prioritize pathways that generate ATP, like glycolysis and the Krebs cycle, and may downregulate pathways like the pentose phosphate pathway that do not directly contribute to ATP production.
