FAQs on NCERT Solutions for Class 10 Science Chapter 6 - Life Processes
1. What are Enzymes? Give one Example of the Enzyme Present in the Human Body and Write its Function in the Human Body?
Enzymes are biological molecules that significantly speed up the rate of chemical reactions in a cell within a human body. They are an essential part of life, and they serve a wide range of functions in the body. From digestion to maintaining one's body's metabolism, enzymes are working everywhere to make things easier for the human body.
Enzymes help in breaking large molecules into smaller pieces so it can be easily absorbed by the body. Other than that, enzymes help in binding two molecules together to produce new molecules. Each enzyme has its own work to do, so they are selective catalysts meaning they only speed up a specific reaction in the human body. Respiration, excretion, etc. are different forms of life processes and work of enzymes in a body.
2. Why do Herbivores Have Much Longer, Smaller Intestine in Comparison to Carnivores?
Herbivores are animals that consume plants and no meat for their food intake. The plants and the byproducts that the herbivores animals eat contain cellulose in their cell wall. As a result, when it comes to digestion of cellulose in the gut takes a longer time; hence animals need larger, small intestine.
3. What concepts are used in Chapter 6 of Class 10 Science?

4. In the human digestive system, what are the functions of the pancreas and liver, according to Chapter 6 of Class 10 Science?
The liver does the secretion of the bile juice. This bile salt helps break down the large globules of fat so that enzymes can act on them. The organ pancreas secretes the pancreatic juice, which contains enzymes like trypsin used to digest proteins. The enzyme lipase is used for breaking emulsified fats. The intestinal juice secreted by the glands of the small intestine converts proteins to amino acids, carbohydrates into glucose, and fats into glycerol and fatty acids.

5. How is oxygen used by different types of animals, according to Chapter 6 of Class 10 Science?
The organisms living on the land use oxygen directly from the atmosphere. The different organs absorb this oxygen. These organs have a structure that increases surface area to absorb this oxygen. Marine animals have to use dissolved oxygen. The amount of oxygen in water is fairly low as compared to the atmosphere. Because of this, the breathing rate of aquatic animals increases. The fishes take oxygen from the mouth, and then the oxygen passes through the gills, which are taken up by the blood.
6. How does the excretory system work in the human body, according to Chapter 6 of Class 10 Science?
The excretory system of the human body consists of the following organs, a pair of kidneys, a pair of ureters, a urinary bladder, and a urethra. The kidneys produce urine which passes into the urinary bladder through the ureters. Kidneys are also known as basic filtration units. Each kidney has filtration units called nephrons which are present in large numbers. This urine is stored in the urinary bladder, which is passed out through the urethra.
7. What are the major differences between arteries and veins, according to Chapter 6 of Class 10 Science?
Arteries:
These vessels carry oxygenated blood except for pulmonary arteries.
The walls of the arteries are elastic and thick.
The arteries are located deep inside the body.
The colour of the arteries is red.
These help in transporting blood away from the heart to different organs.
Veins:
The veins carry deoxygenated blood except for the pulmonary veins.
These have thin walls.
The location of the veins is closer to the skin.
The colour of the veins is blue.
The transportation of blood to the heart from various parts of the body is done by veins.
