D)radioactive cAMP.
E)cameleons.

Question

Quizplus · Accepted Answer

Cameleons are fluorescent biosensors that are capable of measuring changes in calcium concentrations within living cells. Therefore, they would be the best choice for observing cytosolic calcium fluxes in order to determine if they are associated with signal transduction in a particular cell type. Caspases are a family of cysteine proteases involved in programmed cell death and not used for observing calcium fluxes. Cytochrome c is a protein essential for electron transport chain and is not used for observing calcium fluxes. Nitric oxide is a gaseous signaling molecule and is not used for observing calcium fluxes. Radioactive cAMP is not used for observing calcium fluxes as it measures intracellular levels of cAMP.
