QUESTION 10

1. Marasmus is protein-deficiency malnutrition, while Kwashiorkor is energy-deficit malnutrition

   True

   False

Answer 1

Question1-(d)  all of the above are possible results. Excessive protein intake results in weight gain or obesity, dehydration, increased excretion of urea by kidney and glucose formation.

Question 2- (a) transcription in the nucleus, and translation in the ribosomes. The protein synthesis takes place in two phases, transcription and translation.  Transcription takes place in the nucleus, and translation in the ribosomes. MItochondria produces ATP. and golgi body converts proteins into lipids.

Question 3-(f) providing energy Proteins are the building blocks of the body. Proteins perform the following functions of promoting bulk of the stool, making hormones, making enzymes, aiding in immune function and providing cell structure.

Question 4- (d) a feverish person with loss of appetite A Positive nitrogen balance is formed during pregnancy, growth spurt and athletic training.This is due to rapid growth or metabolism taking placing inside the body.

Question 5- (c) fat-free milk Animal protein is considered as a complete protein while plant protein lacks some essential amino acids. Fat free protein is an example of complete pritein.

Question 6- (f) all of the above statements are correct regarding vegetarian diet. All the other aspects are true. Vegetarians have risk of nutritional deficiency as the vegeterian diet lacks certain amino acids, vitamins etc. Well planned diet with nutritional supplements, like certain algae, seaweed, can help overcome the nutritional deficiency.

Question 7- (c) 48 grams, 10-35% A human being should get approximately 10-35% of energy from proteins in their diet. The RDA is 0.75g protien for 1 kilogram of body wait.

Question 8- (d) quaternary The hemoglobin has quaternary structure consisting of four polypeptide bonds around it.

Question 9-(c) transamination, gluconeogenesis Transamination involves synthesis of nonessential amino acids and gluconeogenesis involves making glucose from non-carbohydrate source. Deamination is the process of removal of an amino acid from a molecule.Glycolysis is the process of producing energy from glucose.

Question 10-(b) false Marasmus is energy-deficit malnutrition, while Kwashiorkor is protein-deficiency malnutrition.
