What do all organisms have that is invisible because it involves small differences in biochemical processes?

All organisms share metabolism , which is the set of chemical reactions that occur within their cells to maintain life. These reactions involve the breaking down of nutrients for energy and the building up of complex molecules necessary for growth and repair.

성장과 움직임과 같은 신진 대사의 외부 표현을 볼 수 있지만 실제 화학 과정 자체는 보이지 않습니다 to the naked eye. These processes are based on tiny molecules and involve subtle changes in their structure and interactions.

Here are some examples of invisible aspects of metabolism:

* 효소 : These proteins act as catalysts, speeding up specific chemical reactions. Their action is invisible, but their presence is essential for life.

* 세포 호흡 : The process of breaking down glucose for energy involves a complex series of reactions involving molecules like ATP and NADH. These reactions are microscopic and invisible.

* 광합성 : Plants use sunlight to convert carbon dioxide and water into sugars. This process involves the absorption of light energy, the transfer of electrons, and the creation of chemical bonds. All of these steps occur on a molecular level and are invisible.

So, while we may not see the intricate workings of metabolism, it's the driving force behind life for all organisms, from the simplest bacteria to the most complex animals.
