Answers: 1. c, 2. b, 3. b, 4. a, 5. b, 6.a, 7.b, 8.d, 9.b, 10.b
 
 Answer the following questions

• Process of obtaining nutrients from the environment i.e. intake of food and then its digestion in the body.
• Two types – Autotrophic (self-sufficient for food) and Heterotrophic (dependent on others for food).
 
2. Write short notes on nutrition in human beings Nutrition in human beings is Heterotrophic nutrition
 
• Generally take up energy from plants and animals by using them as food
• It is included under holozoic mode of heterotrophic nutrition
• Human digestive system- consists of the long alimentary canal that includes mouth, pharynx, oesophagus, stomach, small intestine, large intestine, rectum and anus.
• Organs for assistance- pancreas, liver
 
3. What is the role of tongue in digestive process?
 
Answer: Tongue helps in chewing, moistening, rolling and swallowing of food.
 
4. Write the importance of small intestine in digestion.
 
Answer: It is the longest part (about 7.5 m long) of alimentary canal. It is the site where complete digestion of carbohydrates, proteins, and fats takes place. It gets intestinal juices from two different glands – liver and pancreas that help in the further digestion of food.
 
5. What type of nutrition is shown in amoeba? What does it diet include?
 
Answer: Amoeba shows holozoic nutrition. Its diet includes bacteria, microscopic plants like the diatoms, minute algae, and microscopic animals like other protozoa, nematodes and even dead organic matter.
 
6. Name the correct substrates for the following enzymes
(a) Trypsin (b) Amylase (c) Pepsin (d) Lipase
 
Answer: a. Protein b. Starch c. protein d. emulsified fat
 
7. How do carbohydrates, proteins and fats get digested in human beings?
 
Answer:
 
Carbohydrate Digestion
 
Digestion of carbohydrates starts with buccal cavity where salivary enzymes breaks down the starch into simple sugar molecules. Other sugar molecules are breakdown to glucose in small intestine.
 
Protein digestion
 
Proteins are partially digested by pepsin secreted by gastric glands present in the stomach. Then Pancreatic juice secrets trypsin enzymes in small intestine where complete digestion of proteins takes place.
 
Fat Digestion
 
Fats are digested in small intestine. Bile juice present in the liver emulsifies the fat which breaks fats into small globules. These small fat globules are converted into glycerol and fatty acids by Lipase enzyme
