Chapter 42, Problem 14PIAT
Summary Introduction
To review:
The advantage of the difference in the mass of the left ventricle in the heart of athletes and non-athletes.
Introduction:
The ventricle is the large chamber of the heart, which had thick walls in comparison to that of the atria. This is due to the fact that the ventricles face a high blood pressure to supply blood to the entire body. With constant workout and other cardiac condition, which require the heart to pump more blood, the mass of the ventricle changes.
The scientists conducted an experiment on the athletes, non-athletes, and ex-athletes to check the mass of the left ventricle using echocardiography. The results are summarized in the graph given below:
The results suggested that the current athletes had more ventricular mass as compared to the non-athletes.

The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.

- San Andreas Transform Boundary Plate Motion The geologic map below of southern California shows the position of the famous San Andreas Fault, a transform plate boundary between the North American Plate (east side) and the Pacific Plate (west side). The relative motion between the plates is indicated by the half arrows along the transform plate boundary (i.e., the Pacific Plate is moving to the northwest relative to the North American Plate). Note the two bodies of Oligocene volcanic rocks (labeled Ov) on the map in the previous page located along either side of the San Andreas Fault. These rocks are about 23.5 million years old and were once one body of rock. They have been separated by displacement along the fault. 21. Based on the offset of these volcanic rocks, what is the average annual rate of relative plate motion in cm/yr?
