Why lysosome are called suicidal bag?

Posted by Aman Verma 6 years, 11 months ago

CBSE > Class 11 > Biology

2 answers

Yogita Ingle 6 years, 11 months ago

Lysosomes can be termed as waste disposal system of the cell. For almost all type of organic materials they contain digestive enzymes. For example, when cell gets damaged, lysosome may burst and the enzymes digest their own cell. Therefore lysosomes are known as the Suicidal bags of a cell or we can say that they posses different kind of hydrolases on release of these enzymes that cause death of cell.

Lysosome itself burst to destroy an unwanted (damaged or teared) cell. So it is called as suicidal bag.

Why dark reaction is called dark reaction

Posted by Aman Verma 6 years, 11 months ago

CBSE > Class 11 > Biology

2 answers

Yogita Ingle 6 years, 11 months ago

Dark reaction is also called carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from the carbon dioxide and water molecules. This reaction occurs in the stroma of the chloroplast where they utilize the products of the light reaction. Plants capture the carbon dioxide from the atmosphere through stomata and proceed to the Calvin cycle. In the Calvin cycle, the ATP and NADPH formed during light reaction drives the reaction and convert 6 molecules of carbon dioxide into one sugar molecule i.e. glucose.

Give structures, chemical properties of Heavy water and hydrogen peroxide

Posted by Md Arman 6 years, 11 months ago

CBSE > Class 11 > Chemistry

1 answers

Yogita Ingle 6 years, 11 months ago

A peroxide is any compound which has two oxygen atoms bonded together. The O-O group is the peroxide group of the compound. And Hydrogen Peroxide is the simplest peroxide. The chemical formula for hydrogen peroxide is H₂O₂. It is a water molecule with one extra atom of oxygen,.

Properties of Hydrogen Peroxide

Hydrogen Peroxide is an almost clear, pale blue liquid in its pure state
It has an odour similar to that of nitric acid
Hydrogen peroxide has a viscosity higher than water. It is about 40% denser than water
It is acidic in nature.

Heavy water or deuterium oxide (D₂O) is a form of water that contains a large amount of the hydrogen isotope deuterium which is also known as heavy hydrogen.
1)It is colourless, odourless and tasteless mobile liquid heavier than water. Because of higher molecular mass there is a marked difference in physical properties of ordinary water and heavy water.
2)Dielectric constant of heavy water is lower than that of ordinary water therefore ionic compounds are less soluble in heavy water than in ordinary water.

Newton law of motion

Posted by Prashant Kumar 6 years, 11 months ago

CBSE > Class 11 > Physics

4 answers

Ankit Singh 6 years, 11 months ago

Newton’s First Law of Motion also known as Law of Inertia states that every object persists to stay in uniform motion in a straight line or in the state of rest unless an external force acts upon it. Newton’s Second Law of Motion states that force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration, i.e. F = m*a. Learn about the Acceleration in detail here. Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction. Derivation of Newton’s Second Law of Motion According to Newton’s second law: F⃗ =dP⃗ /dt, where P⃗ = momentum and P⃗ =mv⃗ If the time interval for the applied force is increased, then the value of the applied force will decrease. In cricket players use this while catching the ball. They pull their hands back so that time of contact with ball increases and they would experience less jerk due to the motion of the ball. From Newton’s second law of motion, F⃗ ∝dP⃗ /dt F⃗ =k×dP⃗ /dt=kma⃗ For simplicity, the constant of proportionality (k) is chosen to be 1, therefore F⃗ =ma⃗ Hope this will help u

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force acting on an object (if all the external forces cancel each other out) then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. If an external force is applied, the velocity will change because of the force. The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time. Newton also developed the calculus of mathematics, and the "changes" expressed in the second law are most accurately defined in differential forms. (Calculus can also be used to determine the velocity and location variations experienced by an object subjected to an external force.) For an object with a constant mass m, the second law states that the force F is the product of an object's mass and its acceleration a: F = m * a For an external applied force, the change in velocity depends on the mass of the object. A force will cause a change in velocity; and likewise, a change in velocity will generate a force. The equation works both ways. The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B
