Question 2 40 Two beakers are connected at their bottoms by a tube containing a membrane permeable only to water. The left beaker contains 50 ml of 10% sucrose, whereas the right beaker has 50 ml of 1% glucose. After standing overnight, which of the following statements is true? O Both beakers contain 5% sucrose and 0.5% glucose O The left beaker contains 5% sucrose, the right beaker 2% glucose Liquid level in the right beaker has risen, that in the left one has gone down O Liquid level in left beaker has gone up: in the right beaker it has gone down

An easy way to calculate the amount of energy available at each level is to what?

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.

Which three statements represent the benefits of performing experiments using computer simulations?
