Objective: To teach the students about Nutrition in Animals-test1
+
[Author - Anu Nived]
  
  
−
Defenition: Animal nutrition focuses on the dietary needs of domesticated animals, primarily those in agriculture and food production.
+
'''Objective:''' To teach the students about the nutrition process in animals
  
 +
'''Subtopics to be covered:'''
  
−
There are seven major classes of nutrients: carbohydrates, fats, fibre, minerals, protein, vitamin, and water.
+
- Types of nutrition process (ingestion, digestion, absorption, assimilation and egestion)
  
 +
- Human digestion and digestive system
  
−
The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate energy internally, and in either case it is measured in joules or calories (sometimes called "kilocalories" and on other rare occasions written with a capital C to distinguish them from little 'c' calories). Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram.,[1] though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons. A third class dietary material, fiber (i.e., non-digestible material such as cellulose), seems also to be required, for both mechanical and biochemical reasons, though the exact reasons remain unclear.
+
- Digestion in Amoeba
  
 +
- Digestion in grass eating animals
  
−
Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose, fructose, galactose) to complex polysaccharides (starch). Fats are triglycerides, made of assorted fatty acid monomers bound to glycerol backbone. Some fatty acids, but not all, are essential in the diet: they cannot be synthesized in the body. Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen. The fundamental components of protein are nitrogen-containing amino acids, some of which are essential in the sense that humans cannot make them internally. Some of the amino acids are convertible (with the expenditure of energy) to glucose and can be used for energy production just as ordinary glucose. By breaking down existing protein, some glucose can be produced internally; the remaining amino acids are discarded, primarily as urea in urine. This occurs normally only during prolonged starvation.

1. Ask the students to identify the different types of teeth in their mouth.

2. . Prepare a separate sample each of (i) sugar solution, (ii) common salt solution, (iii) lemon juice and (iv) juice of crushed neem leaf or bitter gourd. Blindfold one of your classmates and ask her/him to take out the tongue and keep it in straight and flat position. Use a clean toothpick to put the above samples one by one on different areas of the tongue. Use a new toothpick for each sample. Ask the classmate which areas of the tongue could detect the sweet, salty, sour and bitter substances. (Textbook activity)
