The picture shows an experimental set up for the process of osmosis. the potato has a cavity on top, as shown in the picture. some sugar solution is poured into the cavity and the potato is placed in a beaker of water. after some time, it is observed that there is a rise in the level of liquid in the cavity. this confirms that a) water from the beaker has moved into the cavity. b) sugar has moved out of the sugar solution in the cavity. c) the sugar solution in the cavity has become more concentrated. d) there is equilibrium between the liquids in the beaker and the cavity.

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i.e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.
