Animals

उत्तर
Animals eat green plants or eat animals that feed on green plants.
Respiration - The process of biochemical decomposition of organic compounds like simple carbohydrates, glucose, in living cells with the release of energy.
- Energy is released in the form of ATP (Adenosine triphosphate).
- One mole of glucose on complete oxidation yields 38 molecules of ATP.
- It is a high energy molecule which serves as an immediate source of energy.
- It is a form of chemical energy which can be used for all processes in the cell.
- Therefore ATP is called the currency of the cell.
Metabolism Is the set of life-sustaining chemical reactions within the cells of living organisms
Two Types of metabolic processes take place in living things
|
Catabolic process - it is a destructive (breaking down) process in which energy is released. e.g. Respiration |
Anabolic process - It is a construction (uses energy to construct) process in which energy is used for biosynthetic processes. e.g. Photosynthesis |
