Explanation:
10 question and 5 mark
Answer:
1. (a) Lipase
2. (a) Stomach
3. (a) Amoeba
4. (b) Glucose
5. (d) Proteins, fats and carbohydrates
6. (a) Mucus
7. (d) Lactic Acid
8. (a) Respiration
9. (c) ATP
10. (d) All of the above
Explanation:
1. (a) Lipase
Pancreatic juice is secreted by the pancreas which contains a variety of enzymes including trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase and amylase. Pepsin in not present in pancreatic juice. It is secreted by the peptic cells of the stomach.
So, the correct answer is option (a) Lipase.
2. (a) Stomach
Pepsin in not present in pancreatic juice. It is secreted by the peptic cells of the stomach.
Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach.
So, the correct option is (a) Stomach.
3. (a) Amoeba
Holozoic nutrition is that mode of nutrition in which an organism takes complex organic food materials into its body by the process of ingestion, the ingested food is digested and then absorbed into the body cells of the organism. The undigested and unabsorbed part of the food is thrown out of the body of the organism by the process of egestion. For example, Amoeba, cat, dog, Paramecium, cattle etc.
So, the correct option is (a) Amoeba.
4. (b) Glucose
Autotrophic nutrition is a process in which an organism makes its own food in the presence of sunlight from simple inorganic materials such as water, mineral salts, and carbon dioxide.
So, the correct option is (b) Glucose.
5. (d) Proteins, fats and carbohydrates
Pancreatic juice has three types of enzymes namely, Amylopsin which digests starch (carbohydrates), Trypsin which digests proteins and Steapsin which digests fats.
So, the correct option is (d) proteins, fats and carbohydrates.
6. (a) Mucus
Mucus layer protects the inner lining of the stomach against the HCl present in the gastric juice.
So, the correct option is (a) Mucus.
7. (d) Lactic Acid
Due to anaerobic respiration, there is an accumulation of lactic acid in muscle cells that leads to painful contractions or cramps in leg muscles.
So, the correct option is (d) lactic acid.
8. (a) Respiration
The process of acquiring oxygen from outside the body, and to use it in the process of break-down of food sources for cellular needs, is what we call respiration.
So, the correct option is (a) Respiration.
9. (c) ATP
ATP – Adenosine triphosphate is called the energy currency of the cell. It is the organic compound composed of the phosphate groups, adenine, and the sugar ribose. These molecules provide energy for various biochemical processes in the body. Therefore, it is called “Energy Currency of the Cell”.
So, the correct option is (c) ATP.
10. (d) All of the above
The three episodes that occur during the photosynthesis cycle are: Light energy is absorbed by chlorophyll, which breaks down water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. The reduction of carbon dioxide leads to the formation of carbohydrates.
So, the correct option is (d) All of the above.
