Figure Q15-57 shows the orientation of the Krt1 protein on the membrane of a Golgi-derived vesicle that will fuse with the plasma membrane. Given this diagram, which of the following statements is true?
(a) When this vesicle fuses with the plasma membrane, the entire Krt1 protein will be secreted into the extracellular space.
(b) When this vesicle fuses with the plasma membrane, the C-terminus of Krt1 will be inserted into the plasma membrane.
(c) When this vesicle fuses with the plasma membrane, the N-terminus of Krt1 will be in the extracellular space.
(d) When this vesicle fuses with the plasma membrane, the N-terminus of Krt1 will be cytoplasmic.
