What do testosterone and cortisol have in common?   A. Steroid acute regulatory protein (StAR) is a key point of biosynthetic regulation   B. Most biosynthesis occurs in the adrenal gland   C. High solubility in extracellular fluid   D. Signaling starts with activation of protein kinase C   E. Higher expression in adult males than (non-pregnant) adult females

32. Through our expertise in biochemical manipulation, we found a way to alter the G protein-coupled receptor for follicle stimulating hormone (FSH). The alteration stopped the binding of FSH to the receptor completely stopping all cellular effects. What effect does this have on other hormones that bind to G protein-coupled receptors such as adrenocorticotropic hormone (ACTH), luteinizing hormone (LH), and thyroid stimulating hormone (TSH)? to. It will stop these effects as well since they all use the adenylyl cyclase pathway b. It will only stop the effects of other gonadal hormones such as LH It will stop ALL cellular effects that use G protein-coupled receptors dBoth A and C It will do nothing to any other hormone since all receptors are unique to each hormone

s in th and the development of a tumor. Which of the following is a characteristic of steroid hormones? A. Activation of adenylate cyclase B. Activation of protein kinases C. Plasma membrane receptors D. Stimulation of cellular protein synthesis E. Termination of effects by phosphodiesterase V adenylate cyclase 본 Edit D t 20% 2 C

A loss of function mutation in a gene encoding a SNARE protein would result in which of the following effects? оа. The anterior pituitary would be unable to release its hormones o b. Skeletal muscle cells, but not cardiac or smooth muscle, would lose their ability to contract O c. Neural cells would be unable to generate action potentials d. Neural cells would be unable to transmit action potentials via electrical synapses Neural cells would be unable to transmit action potentials via chemical synapses O e.
