稳态和代谢之间的差异

中的一个关键差异between homeostasis and metabolism is that体内平衡是指能够在体内保持稳定和恒定的内部环境，而不管外部环境的变化如何，而新陈代谢是指生物体内发生的一系列化学反应。

所有生物体都具有某些基本特性，例如细胞组织，敏感性，生长，发展，繁殖，调节和稳态。这些特性基本上使地基奠定了基础。稳态和代谢是生物体一生必须维持的两个主要过程。没有这些过程，生物将无法生存。

什么是体内平衡？

通常，无论环境变化如何，所有生物体都必须保持恒定的内部身体状况。体内平衡是生物体调整自身以限制外部变化并保持身体内部功能状态的这种能力。因此，体内平衡对于生活至关重要。它维护着许多高级生物的大多数调节机制（脊椎动物）例如心率，呼吸速率，血糖水平，液体水平和体温等。稳态的优势在于，它允许生物体在广泛的环境条件下生存并有效地生存并有效地发挥作用。

In many organisms, the nervous system controls the homeostasis via nerve impulses. Maintenance of homeostasis involvesnegative feedback loops该努力朝身体的固定点起作用。例如，当体温升高时，负反馈回路将体温带到设定点37⁰C，这是正常体温。同样，体内平衡在生物体体内保持相对恒定和稳定的环境。但是，干扰负反馈回路的事情可能会破坏体内平衡​​。这样的病是糖尿病，由于胰腺无法产生胰岛素激素。

什么是新陈代谢？

Metabolism is the set of all chemical reactions that occur in an organism. In simple words, it refers to the set of life-sustaining chemical reactions in an organism. Organisms need energy for many of their actions such as moving, breathing, thinking, blood circulation, eating, singing, etc. To produce energy, the body cells convert the fuel (food) into energy by chemical reactions. Some specific proteins in the body control these chemical reactions, and certain body functions coordinate these reactions.

有两种类型的代谢分解代谢和合成代谢。分解代谢是指将有机物分解为小分子的一组代谢途径。另一方面，合成代谢是指构建有机分子（例如蛋白质，脂质，核酸等）的一组代谢途径。所有这些化学反应都使用一系列酶发生。同样，一种化学物质转化为另一种化学物质，其中一系列反应步骤组织为代谢途径。酶在代谢中起着至关重要的作用，因为它们调节反应速率。更重要的是，酶提高了生化反应的速度，并使反应能够快速有效地进行。

稳态和代谢之间有什么相似之处？

• Homeostasis is required for metabolism.
• 稳态和代谢都通过一系列反应发生。
• 另外，两者都发生在活生物体中。

What are the Differences Between Homeostasis and Metabolism?

Homeostasis is the ability to maintain the internal system of an organism in a dynamic constant functioning state. In contrast, metabolism is the collection of all chemical reaction carried out in an organism. Therefore, we can consider this as the key difference between homeostasis and metabolism. Furthermore, there are more differences between homeostasis and metabolism.

Unlike homeostasis, metabolism can be divided into two categories as anabolism and catabolism. Due to the metabolism of the body, certain internal properties (internal body temperature, pH etc.) could be changed. In contrast, regulating and keeping these properties in constant level is done by the homeostasis. So, this is also a significant difference between homeostasis and metabolism. Also, normally, hormones are involved in controlling homeostatic regulations while enzymes are involved as catalysis, and they control metabolic pathways. Thus, we can take this also as a difference between homeostasis and metabolism.

此外，人体中的特定蛋白质控制着代谢反应，而神经系统控制稳态法规。此外，稳态调节机制可以降低或提高代谢率，但不能通过代谢来控制稳态。因此，这些是稳态和代谢之间的一些重要差异。

Summary – Homeostasis vs Metabolism

体内平衡是保持一个稳定的趋势relatively constant internal environment inside the body. On the contrary, metabolism is the collection of all chemical reactions occurring in an organism. Homeostasis is necessary for metabolism. But metabolism cannot control homeostasis. Furthermore, enzymes control metabolism while the nervous system controls homeostasis. This is a summary of the differences between homeostasis and metabolism.
