Chapter 1, Problem 17RQ

MATHEMATICAL Consider the reaction AB+C, where G=0.00. (a) What is the value of G (not G) when the initial concentrations of A, B, and C are 1 M, 103M,and106M? (b) Try the same calculations for the reaction D+EF, for the same relative order of concentrations. (c) Try the same calculations for the reaction GH, if the concentrations are 1Mand103M for G and H, respectively.

In each of the three systems, determine the state of entropy (low or high) when comparing the first and second: i. the instant that a perfume bottle is sprayed compared with 30 seconds later, ii. an old 1950s car compared with a brand new car, and iii. a living cell compared with a dead cell. a. i. low, ii. high, iii. low b. i. low, ii. high, iii. high c. i. high, ii. low, iii. high d. i. high, ii. low, iii. low

MATHEMATICAL Using the information in Table 20.2, calculate G for the following reaction: 2Cytaa3[oxidized;Fe(III)]+2Cytb[reduced;Fe(II)]2Cytaa3[reduced;Fe(II)]+2Cytb[oxidized;Fe(III)]

In the context of cell biology, what do we mean by form follows function? What are at least two examples of this concept?

Calculate the probability of selecting a heart or a face card from a standard deck of cards. Is this outcome more or less likely than selecting a heart suit face card?

MATHEMATICAL Calculate the isoelectric point of each of the following amino acids: glutamic acid, serine, histidine, lysine, tyro- sine, and arginine.

In which direction would an MRI scanner move to produce sequential images of the body in the frontal plane, and in which direction would an MRI scanner move to produce sequential images of the body in the sagittal plane?

Why would it be incorrect to refer to the formed elements as cells?

Why were radioactive sulfur and phosphorous used to label bacteriophage in Hershey and Chase’s experiments?
