Energy-consuming active transport is used to move protons in all of the following directions except: A. from the mitochondrial matrix, across the mitochondrial cristae, into the intermembrane space B. from the extracellular fluid, across the plasma membrane, into the Halobacterium halobium cytosol C. from the cytosol of plant cells, across the vacuolar membrane, into the central vacuole D. from the cytosol of skeletal muscle cells, across the plasma membrane, into the extracellular fluid E. from the chloroplast stroma, across the thylakoid membrane, into the thylakoid space
