Widely praised for its strong biochemistry coverage, Becker’s World of the Cell, Eighth Edition, provides a clear, up-to-date introduction to cell biology concepts, processes, and applications. Informed by many years of teaching the introductory cell biology course, the authors have added new emphasis on modern genetic/genomic/proteomic approaches to cell biology while using clear language to ensure that students comprehend the material. Becker’s World of the Cell provides accessible and authoritative descriptions of all major principles, as well as unique scientific insights into visualization and applications of cell biology.
Sample questions asked in the 8th edition of Becker's World of the Cell: QUANTITATIVE Calculating ? G°? and ? G?. Like Reaction 5-28, the conversion of 3-phosphoglycerate (3PG) to 2-phosphoglycerate (2PG) is an important cellular reaction because it is one of the steps in the glycolytic pathway (see Chapter 9): If the enzyme that catalyzes this reaction is added to a solution of 3PG at 25°C and pH 7.0, the equilibrium ratio between the two species will be 0.165: Experimental values for the actual steady-state concentrations of these compounds in human red blood cells are 61 µM for 3PG and 4.3 µM for 2PG. (a) Calculate ? G °?. Explain in your own words what this value means. (b) Calculate ? G ?. Explain in your own words what this value means. Why are ? G ? and ? G °? different? (c) If conditions in the cell change such that the concentration of 3PG remains at 61 µM but the concentration of 2PG rises, how high can the 2PG concentration get before Reaction 5-29 stops because it is no longer thermodynamically feasible? Mitochondrial Transport. For aerobic respiration, a variety of substances must be in a state of flux across the inner mitochondrial membrane. Assuming a brain cell in which glucose is the sole energy source, indicate for each of the following substances whether you would expect a net flux across this membrane, and, if so, how many molecules will move in which direction per molecule of glucose catabolized. (a) Pyruvate (g) NADH (b) Oxygen (h) FADH 2 (c) ATP (i) Oxaloacetate (d) ADP (j) Water (e) Acetyl CoA (k) Electrons (j) Glycerol-3-phosphate (I) Protons Homeotic Genes in Drosophila. Homeotic genes are considered crucial to early development in Drosophila because ... (Indicate true or false for each statement, and explain your answer.) (a) ... they encode proteins containing zinc finger domains. (b) .. . mutations in homeotic genes are always lethal. (c) ... they control the expression of many other genes required for development. (d) ... homeodomain proteins act by Influencing mRNA degradation.
