Animal nutrition

Exam 3 Essay

Animal Nutrition

Instructions: Answer all three questions completely. Be sure to include the question with the answer so that I can know which question you are answering. You cannot just give the number of the question. If the question is not included with the answer, I WILL NOT grade the answer. If you are in doubt as to whether specific information is needed, include it. I will not accept “I didn’t know that you wanted that information” as an excuse for leaving out information. Be sure to document the location of any information you obtained from additional sources on your answer sheets so that I can go to those sources and verify the information. Do not copy any information word-for word from these sources or utilize sources that are not documented on your answer sheets. All information MUST be in your own words for you to receive credit for the information. If any information is copied from another source or another student, or a sources is used that is not documented on the turned in answer sheet, the information may not be accepted, and the student may not receive any credit for the information. You must submit your answers by email attachment to the following email ( [email protected] ) .  Just make sure you receive a reply indicating that I received the email.  

Answers are due electronically (email attachment only) by the start of finals week.

1. Each of the students has been assigned a triglyceride on the chart below. Using the triglyceride that has been assigned to you, determine and present the following information regarding the animal cell’s ability to obtain energy from the triglyceride molecule.

a. Total number of ATP’s that could theoretically be obtained from a complete breakdown (hydrolysis of ester bonds and beta oxidation of each fatty acid [FA]) of the triglyceride. Be sure to follow the molecules through all pertinent aspects of glycolysis, Kreb’s cycle, and the electron transport chain (ETC). Also, assume that the cell will obtain 3 ATP’s for each NADH entering the ETC and will obtain 2 ATP’s for each FADH2 entering the ETC.

b. The structural formula for each FA and the total number of carbons in each FA obtained from the hydrolysis of the ester bonds.

c. Total number of acetyl CoA’s produced through beta oxidation.

d. Total number of NADH’s produced from the oxidation of the triglyceride (be sure to consider NADH gained or lost from beta oxidation)

e. Total number of FADH2’s produced from the oxidation of the triglyceride (be sure to consider the FADH2’s gained or lost from beta oxidation)

f. The percent increase or decrease over the theoretical 36 ATP’s from 1 molecule of glucose.

2. Prepare a PowerPoint presentation for a vitamin or mineral that we did not discuss in class. The presentation should be designed for a non-scientific audience such as one associated with a community civic organization. In the presentation, be sure to address each of the following topics of the vitamin or mineral chosen.

a. What is a vitamin or mineral (whichever you chose for the presentation)?

b. Function of the vitamin or mineral chosen at a cellular level.

c. How could this vitamin or mineral be classified (fat soluble, water soluble, macromineral, micromineral).

d. Health result of a deficiency of the vitamin or mineral chosen.

e. Basic structure(s) of the vitamin or mineral chosen.

f. What food types contain the vitamin or mineral chosen?

g. Biological activity of the different structures of the vitamin or mineral chosen.

h. How the vitamin or mineral chosen is absorbed in the GI tract.

i. How the vitamin or mineral chosen is transported in the blood stream and/or lymphatic system.

j. Any synergism between or among the vitamin or mineral chosen and other nutrients in the diet. This synergism could be associated with absorption, transportation in the body, and function at the cellular level.

The rubric for grading the presentation is presented below.

3. Attach a picture of a cat food ingredient label to the document with this answer. Be sure it shows all vitamins and minerals that have been supplemented in the food. List each of the vitamins and minerals. Also describe the functions of those vitamins and minerals in the body of a cat. The picture of the label MUST be attached to the document submitted with the answer. I will NOT accept a separate attachment of the picture. The picture and the rest of the answer must be on the same document.
