Chapter 8, Problem 1MCQ
Summary Introduction

Introduction:

The organisms acquire energy by consuming food and converting it into smaller particles and generate energy. The energy is used further for the construction of other biomolecules for building body with the help of smaller biomolecules

Answer to Problem 1MCQ

Correct answer:

Catabolism is a form of metabolism in which large molecules are converted into smallmolecules. Therefore, option (a) is correct.

Option (a) is given as “large, small”.

Explanation of Solution

Justify reasonfor the correct statement:

Catabolism refers to all the destructive processes of the body in which energy is released. Complex molecules are broken down into simpler in catabolism process. Catabolic exercises are associated with burning calorie.

Hence, option (a) is correct.

Justify reasons for the incorrect statements:

Option (b) is given as “small, large”.

Anabolism refers to all the synthesis processes of the body, in which energy is used to make building blocks of the body. Hence, it is a wrong answer.

Option (c) is given as “amino acids, protein”.

The sequence of amino acids joined together by peptide bonds and form a protein molecule. Hence, it is a wrong answer.

Option (d) is given as “food, storage”.

Body stores food by the process of glycogenesis and fatty acid synthesis. Hence, it is a wrong answer.

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

Conclusion

Catabolism refers to the sum total of all destructive processes that release energy, whereas anabolism refers to the sum total of all building processes that require energy. Catabolism and anabolism are the two processes that together constitute metabolism of a body.

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…
