Which of the following would you expect to find in or on cells whose main function is absorption?

a. Microvilli

c. Gap junctions

b. Cilia

d. Secretory vesicles

Expert Solution & Answer

Summary Introduction

Introduction:

Cells are the smallest structural and functional unit of life. The cell has many specialized structures that perform specific functions that are required for proper growth and development of an organism.

Answer to Problem 1MC

Correct answer:

The cells specialized to perform absorption have microvilli over their surfaces. These are hair-like structures that increase the surface area of the cells.

Justification for the correct answer:

Option (a) is given that the cells whose main function is absorption have microvilli in or on them. The body organs like intestines and kidneys perform the function of absorption. Thus, the cells of these organs should have large surface area. This is accomplished by the presence of microvilli (hair-like structures) that extend outward from the plasma membrane.

These provide a brush lining and increase the area of absorption of various nutrients. They also perform the secretory function of some factors. Microvilli are generally present in the small intestine, surface of egg cells, and white blood cells. Hence, option (a) is correct.

Explanation of Solution

Explanation for incorrect answers:

Option (b) is given that the cells whose main function is absorption have cilia in or on them. The cilia are specialized structures on the surface of the cells and provide motility to the cell, in case of prokaryotes. In case of eukaryotes, they perform the function of moving the contents of the organs further. So, it is a wrong answer.

Option (c) is given that the cells whose main function is absorption have gap junctions in or on them. Gap junctions mainly function to pass the ions and molecules freely through the cells. They help in establishing an electrical communication between the cells. So, it is a wrong answer.

Option (d) is given that the cells whose main function is absorption have secretory vesicles in or on them. The secretory vesicles mediate the vesicular transport of cargo between different cells, like hormones or neurotransmitters. So, it is a wrong answer.

Hence, options (b), (c), and (d) are incorrect.

Conclusion

The cells that are specialized to perform the function of absorption are lined by microvilli.

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. Given that the oral bioavailability of this drug is known to be essentially 100%, estimate the following from this…
