Expert Solution & Answer

Answer to Problem 1CRQ

Correct answer: True.

Explanation of Solution

Sarcomeres produce tension efficiently inside the optimal range of lengths. When the resting sarcomere length is in the range, the maximum number of cross-bridges can be formed. This produces great tension. An increase in the length of the sarcomere reduces the tension that is caused by the decrease in the size of the zone of overlap and the number of potential cross-bridge interactions.

An increase in the sarcomere length lessens the tension produced by decreasing the size of the zone of overlap and also the number of potential cross-bridge interactions. Hence, The given statement “An increase in sarcomere length reduces the tension produced in a muscle fiber by reducing the size of the zone of overlap and the number of potential cross-bridge interactions.” is true.

1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just a single route of administration alone. The following data was collected in 250 g rats following bolus iv, oral (po), and intraperitoneal (ip) administration.Using this data and set of graphs, determine: (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data (c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e) absolute po bioavailability, (f)Fpo absolute ip bioavailability, Fip MAKE SURE ANSWERS HAVE UNITS if appropriate. SHOW ALL WORK, including equation used, variables used and each step to your solution.

2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present.
