Explanation / Answer

chapter 6

1.Both anabolism and catabolism are metabolic processes, but the two are contrastingly different from each other.
• Catabolism produces energy but anabolism uses energy.
• In the catabolic pathways, the large molecules are broken down into small monomers whereas, in anabolism, small molecules are connected with each other, to form large molecules.
• Catabolism is independent of anabolism. However, anabolism requires the ATP produced via catabolism.
• Catabolism is functional at a higher rate during an activity, which needs energy to contract muscles, while anabolism is more functional during sleeping or resting.
• Catabolic processes tend towards using up the stored food to produce energy, while anabolic processes likely to form, repair, and furnish the tissues and organs.

2.The capacity to do work is called as Energy. This energy can be stored in different forms. Energy is one of the physical quantities as it is proportional to the mass of the object. The ability of the body to exert a push or a pull against the natural forces like the gravity identifies as to what kind of energy is it. When an object is at rest, the body is said to possess potential energy. In another case, when the object is in motion, then it is said to possess kinetic energy.
Potential energy tends to affect the object within the environment if and only when it gets transformed to other kinds of energy. A rock which rests at the top of cliff said to be an example of the body possessing potential energy. When the rock falls, it possesses kinetic energy. The energy which is stored in a body because of the elevation is called as gravitational potential energy. Some bodies like waterfalls contain both kinetic as well as potential energy. The height of the waterfall is one of the basis for potential energy, while the movement of water is a base for the kinetic energy.
The property of body decides as to what kind of energy is contained in it. The Potential energy changes into kinetic energy when an object moves. Unlike the potential energy, the kinetic energy can be transferred from one body to another body by the process of collision.
The difference between these two kinds of energies are as explained below-
# Kinetic Energy
@ Potential Energy
1.
# Kinetic energy is the kind of energy present in a body due to the property of its motion
@ Potential Energy is the type of energy present in a body due to the property of its state
2.
# It can be easily transferred from one body to another
@ It is not transferrable
3.
# The determining factors for kinetic energy are Speed or velocity and mass
@ Here, the determining factors are Height/ distance and mass
4.
# Flowing water is one of the examples for kinetic energy
@ Water present at the top of hill is an example of potential energy
5.
# It is relative with respect to nature
@ It is non-relative with respect to nature .

you must post only one question at a time. Because an expert could not answer so many questions in the given time limit to him/her. Please keep this thing in mind from next time onwards. I have solved two questions from chapter 6 because the questions in chapter 5 are not clear. Hope you understand. Thank you!
