Which of the following statement is correct about intracellular signal transduction? A. Most extracellular signals bind to receptors that serve as transcription factors to change gene expression. B. Many signaling pathway involves the use of phosphatases to create phosphorylation cascade and pass on the signal intracellularly. C. Small molecules like cAMP and Ca2+ are often involved in signaling pathway as second messengers. D. There is no two signaling molecules can trigger the same cellular responses.

Which statement about biological signaling (biosignaling) is NOT true? A.) Some membrane-associated receptors can activate kinases inside the cell cytoplasm. B.) Cyclic AMP (cAMP) is produced from ATP and is an important intracellular messenger. C.) Some biological signals are transduced by the opening of membrane ion channels. D.) G proteins are "molecular switches" that are activated by glucose (hence the G in the name). E.) Diacylglycerol is an important signaling molecule that is produced from phospholipids.

In signal transduction (a) an extracellular signal is converted to an intracellular signal (b) a signal is relayed through a series of molecules in the membrane (c) signal molecules are destroyed before target cells can respond to the signal (d) answers a, b, and $c$ are correct (e) only answers a and b are correct

During signal transduction (a) the cell converts an extracellular signal into an intracellular signal that leads to a change in some cell process (b) a signaling molecule directly activates or represses several genes (c) each enzyme catalyzes production of one molecule of product (d) enzymes in the signal cascade remain active until the last component of the pathway alters a cellular process (e) the signal is terminated by cyclic AMP
