17 What locks all transmembrane proteins in the bilayer? a) Chemical bonds that form between the phospholipids and the protein. b) Hydrophobic interactions between nonpolar amino acids of the proteins and the aqueous environments of the cell c) Attachment to the cytoskeleton d) The addition of sugar molecules to the protein surface facing the external environment True/False 1 Lipids yield more energy per gram than carohydrates 2 Fatty acid molecules are amphipathic by nature give both answer asap thanks

Some cells in the pancreatic acinus form vesicles containing zymogens. Then the cells secrete the zymogens. Certain proteins called v-SNARES play a role in this process. What best describes the proteins called v-SNARES? a.) v-SNARES are proteins on the cytosolic face of the plasma membrane that help vesicles to fuse with the plasma membrane b.) v-SNARES are a type of glycosphingolipid in the vesicle lipid bilayer that help maintain vesicle integrity c.) v-SNARES are proteins on the surface of vesicles that help the vesicle fuse with the cytosolic face of the plasma membrane d.) v-SNARES are proteins contained inside of vesicles that help stabilize the vesicle contents until the vesicle fuses with the cytosolic face of the plasma membrane
