Which of the following is an important signaling molecule that controls global gene expression during starvation?
A) cyclic AMP
B) ADP
C) ATP
D) glucose
E) water

Question

Quizplus · Accepted Answer

Cyclic AMP (cAMP) is an important signaling molecule that controls global gene expression during starvation. During nutrient limitation, cAMP levels increase, which can activate various genes that are involved in energy production and stress response. cAMP is also involved in regulating the expression of the lac operon in bacteria. ADP and ATP are important molecules for energy production, while glucose is a sugar that can be utilized by cells for energy. Water is not a signaling molecule involved in gene expression.
