Concept explainers

The electron transport chain, also known as the electron transport system, is a group of proteins that transfer electrons through a membrane within mitochondria to create a gradient of protons that drives adenosine triphosphate (ATP)synthesis. The cell u…

Metabolism

Picture a campfire. It keeps the body warm on a cold night and provides light. To ensure that the fire keeps burning, fuel needs to be added(pieces of wood in this case). When a small piece is added, the fire burns bright for a bit and then dies down unl…

Cellular Respiration

Cellular respiration is the cellular process involved in the generation of adenosine triphosphate (ATP) molecules from the organic nutritional source obtained from the diet. It is a universal process observed in all types of life forms. The glucose (chem…

Textbook Question

Chapter 3, Problem 28E

As you know, fatty acids can be oxidized to provide energy for making ATP. This process begins with a set of reactions known as the fatty acid oxidation cycle, or beta oxidation. Before entering the cycle, a fatty acid reacts with coenzyme A to form a molecule called fatty acyl CoA. This molecule then enters the cycle and continues to go through it until all its carbons have been eliminated, as shown on the following page. From your examination of this diagram, answer the following questions for a 1 2-carbon fatty acid.

How many acetyl CoA molecules will be produced by beta oxidation of this fatty acid? How many ATP molecules can be produced from each acetyl CoA molecule that goes through the Krebs cycle and oxidative phosphorylation?
How many NAD+ and FAD molecules will be reduced? (Hint: How many bonds must be broken to split a 12-carbon fatty acid into acetyl CoA molecules?)
How many ATP molecules will be produced per each NADH + H+ and each FADH₂ molecule that provides electrons to the electron transport system?
It takes two ATP molecules to get the cycle started. Based on this information and your answers to the previous questions, how many ATP molecules can be generated from a 1 2-carbon fatty acid?

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…

The current nutrition labelling regulation in Hong Kong requires food manufacturer to list E+7 information on the package of pre-packaged food products. Do you think that more nutrients, such as calcium and cholesterol, shall be included?
