In bacterial cells and plant cells, cell walls function in
maintaining cell shape.
Which of the following is an incorrect match of molecule to the location where it is principally used?
glucose - lysosome
What does the folding of the mitochondrial inner membrane provide?
greater surface area for ATP production
Which statement below is correct when comparing plant and animal cells?
