Question

Choose all of the following that are differences between kinase receptors and G- protein linked receptors. a) Kinase receptors span the membrane one time while G-protein linked receptors span the membrane many times b) Kinase receptors phosphorylate other proteins while G-protein linked receptors do not c) There are no differences between Kinase and G-protein linked receptors d) G-protein linked receptors bind to steroids while kinase receptors do not e) G-protein linked receptors are are attached to a G protein while kinase receptors are not

Answer 1

4.- The answer are option a, b, d and e

5.- In this question actually all the answers are correct. The leader sequence is a crucial signal for the protein to take this secretory pathway, it will be translate in the ER (not in cytoplasm) so it can be included in a vesicle. All the vesicles from ER have to pass through Golgi to finally get exocytosed, thus secreted.

6.- That is option a) SRP (signal recognition protein)

7.- That is option b) Glucose. The rise in glucose is the signal for insuline release, there is nothing more needed
