Which of the following is/are response(s) of target cells ? The production and storage of another hormone signal Phosphorylation of enzymes The release of a hormones signal by exocytosis transduction

Which of the following statements describes a likely effect of a drug that enhances testosterone (a steroid) binding to its receptor in human cells? The cytosolic levels of CAMP would decrease. The production of particular proteins would begin The cytosolic calcium concentration would increase. The activity of G proteins would decrease.

In which of the following pathways are the receptor and ligand, both, membrane bound proteins? O Hedgehog signaling pathway Wnt signaling pathway Notch/Delta signaling pathway Cytokine receptors - JAK/STAT signaling pathway

Which chemical signaling affects neighboring cells? Group of answer choices neuron autocrine endocrine paracrine

Which is a correct explanation of an aspect within G protein signaling pathway? ATP powers the G protein to cause it to move and activate an enzyme O GTP activates the G protein causing it to move to activate the next protein O The receptor is active when bound to GTP GTP causes the G protein to activate and bind to the receptor

Which of the following statements about the role of ATP in cell signalling is correct? Choose only the best answer. All of the other options are correct. ATP functions as a secondary messenger. ATP is involved in the activation of G protein-coupled receptors. ATP is involved in the activation of some proteins that serve as relay molecules.

A 67-year old man has been treated for prostate cancer. He is receiving a drug that blocks testosterone from binding to its intracellular receptor. Which of the following has this mechanism of action: Tamoxifen Flutamide Leuprolide Fulvestrant Interleukin-2

Received information is called a transduced signal because: this process often has many steps of information conversion. it is then converted into other electrical forms. it is then converted into other chemical forms. many different molecules form a signaling cascade. it is then converted into other chemicals during metabolism.
