NSCI homework 10/11. Please help :) NSCI homework 10/11. Please help :) Please answer each question following below. You are allowed to use resources (e.g, textbooks or journal articles) to support your answers, though you do need to be sure to reference or cite any of these resources correctly. You may find it useful to discuss your answers with a friend (or friends) in class. You should not, however, copy or share your final answers with each other. Any assignment submitted with some similarity to other student submissions may be considered a violation of the OSU Academic Integrity Policy (3 Points) Assuming that an 21 year-old female weighing 135 Ibs requires 0.8 g protein/kg body weight per day to be in zero nitrogen balance, determine how much dietary nitrogen would be required to mee this individual's needs. Please show all calculations below. 1. (2 Point) Referring to the previous question, how many grams of dietary nitrogen would be excreted in the urine assuming that losses through in the feces or from the skin (and other insensible losses) account for 6% of nitrogen losses per day? In what form is the majority of the urinary nitrogen excreted? 2.Explanation / Answer
1. Given that requirement of protein = 0.8 g/kg
Body weight in kg = 135 × 0.454 = 61.29 kg
Protein requirement = 0.8 × 61.29 = 49.032 49 g
Protein contains approx. 16.25% nitrogen.
Hence, dietary nitrogen requirement = 49 × 16.25% = 7.9625 8 g*
2. Amount of nitrogen lost = 8 × 6% = 0.48 g
Majority of the nitrogen excreted in urine is in the form of urea.
(*Please note that the question does not specify whether the value of 0.8 g/kg/day is of dietary, digestible or metabolizable protein. I have calculated my answer based on the assumption that it is dietary protein requirement. Also, I have assumed that the protein is of high quality i.e. 100% digestibility. If you wish to consider any alternate parameters, write them out as a comment and I shall be happy to review my answer for you.)
