(a) Low extracellular pH activates TRPV1 through the binding of H+ ions to TRPV1. Describe
the properties, including the location, of the site of TRPV1 that allow H+
ions to bind. Describe
the specific location in the cell where ATF3 protein is produced.
(b) The pGoG protein is known to block the G1 to S transition in the cell cycle. Explain why
this prevents mitosis from happening in the cell.
(c) Before treating melanoma cells (cancerous cells) with capsaicin, researchers pretreated the
cells with an inhibitor of calcineurin. Predict the effect of this pretreatment on the ability of
capsaicin to induce apoptosis by the pathway shown in Figure 2. Provide reasoning to justify
your prediction.
(d) Researchers claim that many cancers include a mutation in the gene encoding pGog.

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center. because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane. the diverse proteins found in and attached to membranes perform many important functions. the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together. membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.

Which of the following is a testable hypotheses?
