Both metabolism and digestion are important processes that occur in living organisms. As mentioned above, metabolism refers to the whole set of chemical and physiological reactions occurring in a living organism, including the animals and plants. Digestion, which is the breakdown of food, is also a part of metabolism.

什么是新陈代谢?
Metabolism is an extremely vital set of biochemical reactions taking place in order to sustain the life of organisms. Metabolic processes are essential to maintain the growth and development of the organisms, and the extraction of energy through metabolic pathways. Metabolism consists of two major processes known as分解代谢和合成代谢,分别负责收获和消费能量。此外,消化等分解代谢过程将有机物分解为小分子,细胞呼吸产生并满足能量需求。使用在分解代谢过程中产生的能量,合成代谢过程形成重要成分,例如蛋白质和核酸,以维持生物体的生命。
The metabolic reactions are well organized as pathways due to the controlling of hormones and enzymes. Interestingly, metabolic pathways of all organisms are remarkably similar even in very distinctive species. Ecology and evolutionary biology provide explanations for these remarkable similarities. That means; the potential of metabolic activity determines the sustainability of life of a particular organism.
What is Digestion?
Digestion is the breaking down of food. Digestion usually contains a series of processes. There are two main types of digestion:机械消化和化学消化。在消化中,将大分子简化为小单体。因此,消化是一个分解代谢过程。此外,基于操作地点,主要有两种消化系统形式。原始生物具有外部消化,而越来越多的先进动物具有内部消化系统。
在先进的动物中,消化从口中开始,继续穿过胃,并在空肠。While food passes through the oesophagus, the peristaltic movements help to breakdown it into smaller particles. Inside the stomach, the chemical digestion becomes predominant with the secretion of digestive enzymes and acids with optimum temperature. Protein digestion starts in the stomach and ends up in the small intestine after converting proteins into their monomers; amino acids. Lipid digestion starts and ends in the small intestine, which converts lipids into their monomers: glycerol and fatty acids. The mouth starts carbohydrate digestion, and it concludes in the small intestine after forming simple sugars. After all the digestive processes, the nutrients in food are ready for the absorption into the bloodstream.
代谢和消化之间有什么相似之处?
- 代谢和消化是生物体中发生的重要过程。
- Both processes include catabolic reactions.
- 化学消化或食物的酶促分解是一种代谢过程。因此,化学消化属于代谢领域。
- 此外,酶参与这两个过程。
代谢和消化有什么区别?
Both metabolism and digestion are reactions occurring in an organism. Digestion is a part of metabolism. Metabolism is the all chemical and physiological reactions occurring in a living organism that are necessary to maintain life. On the other hand, digestion is the breakdown of foods into small molecules that can be absorbed into the bloodstream. Therefore, this is the key difference between metabolism and digestion.
Moreover, digestion occurs only in the digestive system, but metabolism occurs in all systems in our body. Also, a further difference between metabolism and digestion is the type of reactions they involve. Metabolism includes both catabolic and anabolic reactions, but, digestion includes only catabolic reactions.
此外,消化仅发生在动物中,而代谢发生在所有生物体中。因此,这也是代谢和消化之间的显着差异。
摘要 - 代谢与消化
Metabolism refers to the whole set of chemical and physiological reactions occurring in a living organism including the animals and plants. In contrast, digestion, a part of metabolism, refers to the chemical and mechanical reactions involving in the breakdown of ingested foods into small molecules in order to absorb into our body. Digestion is a type of catabolism. But, metabolism consists of both catabolism and anabolism. Furthermore, metabolism occurs in all the organ system in our body while digestion occurs only in the digestive system. Moreover, metabolism takes place in all living organisms while digestion takes place only in animals. Thus, this is a summary of the difference between metabolism and digestion.
