Describe features of prokaryotes that enable them to thrive in a wide range of different environments.

Expert Solution & Answer

Summary Introduction

To describe: The features of prokaryotes to enable them to thrive in varied environments.

Introduction: Prokaryotes are small unicellular organisms that exhibit peculiar features in their structural organization that make them adapt to a varied range of different environments. These features include the presence of peptidoglycans cell wall, flagella, endospore formation, and resistant genes in plasmids.

Explanation of Solution

The cell walls of prokaryotes are peptidoglycan in nature, which protect the cell, maintain its shape, and prevent it from bursting into the hypotonic environment. In many prokaryotes, the cell wall is surrounded by a sticky coat of polysaccharides or protein, which is known as a capsule. The capsule and slime layers protect the organisms against dehydration and attack their host immune system. Certain bacteria exhibit the property of endospore formation, which enables them to cope up with scarcity of water and nutrients. During the endospore formation, the entire water content is removed to halt the metabolism of bacteria, so that they can survive in the extreme environment in a dormant stage and regain viability even after centuries when they resume their metabolism in a favorable environment. The prokaryotes exhibit short generation time with a large population size, which results in the new mutations to increase the genetic diversity to adapt the variations in a local environment, and thus leading to the evolution. Although the bacteria contain a single chromosome, they may also contain plasmids to carry few genes that provide them antibiotic resistance.

Conclusion

There are several features that help the prokaryotes to survive in extreme conditions.

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…
