The most regsengble explanation for this observation Is that A) plant cells are capable of having a much higher surface-to-volume ratio than animal cells.

What would happen in each of the following cases? Assume in each case that the protein involved is a soluble protein, not a membrane protein. You add a signal sequence (for the ER) to the N-terminal end of a normally cytosolic protein. You change the hydrophobic amino acids in an ER signal sequence into charged amino acids. You change the hydrophobic amino acids in an ER signal sequence into other hydrophobic amino acids. 4 You move the N-terminal ER signal sequence to the C-terminal end of the protein.arrow_forwardUsing the the enzyme acid hydrolase in the lysosome: What is the final destination in which the protein will function?
