21. What would be the outcome of cells expressing a key tricarboxylic cycle (TCA) enzyme lacking an N-terminus amphipathic sequence? a) the cells would have reduced secretion of proteins b) the cells would exhibit reduced mitochondrial respiration c) the cells would have decreased receptor mediated endocytosis d) the cells would exhibit reduced import of proteins into the nucleus 22. What would be the consequence of a mutation in a nuclear GEF that prevents it from exchanging GTP for GDP? a) Protein transport into the nucleus would be halted b) Proteins in the nucleus would be depleted by their excessive transport into the cytosol c) Proteins would accumulate in the nucleus and not perform their normal function d) Cytosolic proteins would fail to bind importin
