Respiration is catabolic and exergonic.

Respiration is the process by which organisms convert energy stored in the chemical bonds of organic molecules into usable energy in the form of ATP (adenosine triphosphate). It can be divided into two main types: aerobic respiration, which requires oxygen, and anaerobic respiration, which does not.

Catabolic Process:
Respiration is a catabolic process because it involves the breakdown of complex organic molecules, such as glucose, into smaller, simpler molecules. During respiration, glucose is oxidized to produce carbon dioxide, water, and energy in the form of ATP. This breakdown of glucose releases energy that was stored in its bonds. Catabolic processes provide the necessary building blocks and energy for anabolic processes, such as the synthesis of new molecules.

Exergonic Process:
Respiration is also exergonic because it releases energy. Exergonic reactions release energy as a byproduct, which is used to perform work in the cell. In the case of respiration, energy is released as glucose is broken down and ATP is produced. This energy is then utilized by the cell for various cellular processes, including growth, movement, and active transport.

Overall Explanation:
So, respiration is catabolic because it involves the breakdown of complex molecules, and it is exergonic because it releases energy. The breakdown of glucose during respiration allows cells to obtain the necessary energy to carry out their functions. The energy released is stored in the high-energy bond of ATP molecules, which can be readily used by the cell when needed.

In conclusion, respiration is a catabolic and exergonic process that breaks down organic molecules, such as glucose, to release energy in the form of ATP. This energy is essential for the functioning and survival of cells.

Respiration is a catabolic and exergonic cellular process. Respiration, which is also known as cellular respiration, is an enzymatic process of biological oxidation of food materials in a living cell, using molecular O₂, producing CO₂, H₂O and releasing energy in small steps and then storing it in the form of ATP. When required, this ATP is utilised by the cell. Chemically it is a catabolic process and brings about the oxidation and decomposition of organic compounds like carbohydrate, fat, protein in the cells of plants and animals with the release of energy. But all the energy present in respiratory substrate is not released free into the cell.
