Describe the three mechanisms via which the transport of a solute against its free energy gradient can be coupled to a source of energy (identify the source of energy in each case). Explain the difference between direct (primary) and indirect (secondary) active transport and discuss how these two processes are "connected" to each other in cells. Think about how the effect of Na+/K+ ATPase (Na+/K+ pump) on the intracellular concentration (and electrochemical potential) of Na+ can be used to drive...

Signal transduction pathways are central to the regulation of cellular processes. Which of the following statements is not true of signal transduction pathways? Group of answer choices Signal transduction pathways typically involve the activation of protein kinases and protein phosphatases. When a hormone binds to a G-protein-coupled receptor, a conformational change in the receptor activates the associated GTP-binding protein. Intracelluar second messenger molecules include cGMP, calcium ions and inositol trisphosphate. A receptor protein has an extracellular domain that is responsible...
