Pepsin and trypsin function |
|
Answer» Trypsin and pepsin are two proteases which act on proteins and break down into peptides and amino acids. Trypsin is produced by the pancreas and secreted into the small intestine. Pepsin is produced by stomach glands. It is one of the main gastric enzymes. This is the difference between trypsin and pepsin.\tPepsin and trypsin break down proteins. Both are principal proteases in the human digestive system.\tBoth enzymes are secreted in inactive forms such as pepsinogen and trypsinogen. Pepsin is the protein digesting enzyme secreted by gastric glands.Trypsin for digesting proteins. |

What are the difference between fission and budding? |
| Answer» Binary fission occurs under favorable environmental condition. It is the division of one cell into two similar cells.this is the simplest way of asexual reproduction. It occurs in unicellular organism like bacteria, yeast, Euglena ,Amoeba and paramoecium. Where as some times new individual develop from the body wall of the parents as a bulblike projections called buds. The bud may unicellular or multicellular depending upon the parents type organism.

Describe how soaps is prepared |
| Answer» Animal fat or vegetable oil act as glyceride or glyceryl ester. And sodium hydroxide and potassium hydroxide act as bases.Take about 30 ml of vegetable oil in a beaker. Then add 60 ml of 20% sodium hydroxide solution to it.This mixture is heated slowly till it boils. After the mixture has boiled for five to ten minutes add 5grams of sodium chloride in order to separate soap from the solution. Allow the solution to cool. The creamy layer floating on top of the solution is the soap.\xa0Thus soap is prepared by hydrolysing fat or oil with bases such as sodium hydroxide or potassium hydroxide This process of soap preparation is known as saponification.Generally soaps are prepared by heating animal fat or oil with alkalies like sodium hydroxide or potassium hydroxide. This is saponification reaction.Fat or Oil + Alkali → Soap + Glycerol\xa0 | |

State in brief of the action of soaps in removing oily spot from a shirt? |
| Answer» Most dirt is oily in nature and oil does not desolve in water . The soap molecules when disolved in water from nucleas with their tails inside and heads outside. This forms an emulsion in water. The micelles stay in the solution as colloid and will not come together to precipitate because of ion-ion repulsion. Thus, the dirt suspended in the nucleas can be easily rinsed away. | |

What is the difference between the chemical composition of soaps and detergents? |
| Answer» \tSoapsDetergentsConsist of a ‘-COONa’ group attached to a fatty acid having a long alkyl chain.Consist of a ‘-SO3Na’ group attached to a long alkyl chain.They are not effective in hard water and saline waterThey do not lose their effectiveness in hard water and saline water.Soaps are completely biodegradableDetergents containing a branched hydrocarbon chain are non-biodegradableThey have a tendency to form scum in a hard water environment.These compounds do not form scum.They are derived from natural sources such as vegetable oils and animal fats.Detergents are synthetic derivatives.Soaps are environment-friendly products since they are biodegradable.These compounds can form a thick foam that causes the death of aquatic life.Examples of soaps: sodium palmitate and sodium stearate.Examples of detergents: deoxycholic acid and sodium lauryl sulfate.\t | |

Newton 1st law |
| Answer» Definition:“A body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it.”Putting Newton’s first law in simple words, a body will not start moving until and unless an external force acts on it. Once it is set in motion,it won’t stop or change its velocity until and unless some force acts upon it once more. Let us understand Newton’s First Law of Motion by an example: Let’s take a block on a smooth surface. By smooth, we mean that there is no friction acting on the surface. The block is at rest, that is, it is not moving.Now, let’s examine the forces acting on the block. The only forces acting on the block are the force of gravity and the normal reaction by the surface. There is no force acting on it in the horizontal direction. Since the forces in the vertical direction are equal to each other in magnitude, they cancel each other out, and hence there is no external force on the block. Since this block is at rest, we can say that it confirms Newton’s first law of Motion.Newton’s First LawNow, if we apply a constant force F on the block in horizontal direction, it will start moving with some constant acceleration, in the direction of the applied force.Newton’s First LawThus, Newton’s first law is confirmed again.Note: Newton’s laws are valid only in inertial frames of reference. Examples of Newton’s First Law of Motion in daily life: Wearing a seat belt in a car while driving is an example | |
