Question

When does the Signal Transduction step occur during cell communication (or cell signaling)? After the cellular response. Before both the receptor is activated and the cellular response occurs. Before the receptor is activated but after the ligand binds. Signal Transduction is not a part of cell communication. After receptor activation but before the cellular response. A chemical reaction that has positive free energy (delta G > 0) is correctly described as endothermic. exothermic. endergonic. enthalpic. spontaneous

Explanation / Answer

Q40. E. after receptor activation but before the cellular response .... signalling is always the intermediate step between cause and effect

Q41.C. Endergonic ... endergoinic reaction require a positive input of energy so deltaG will be positive
