Macromolecules proceed through a process of polymerization, where smaller subunits called monomers are joined together to form larger molecules. This process is driven by specific enzymes that catalyze the formation of covalent bonds between the monomers. Once the macromolecule is formed, it can undergo further modifications and interactions to fulfill its specific biological function. Overall, the process of macromolecule formation is highly regulated and essential for the structure and function of living organisms. **

Macromolecules suitable for fiber production include proteins and polysaccharides. Proteins, such as silk and wool, are suitable for fiber production due to their strong and flexible nature, making them ideal for textiles. Polysaccharides, such as cellulose and chitin, are also suitable for fiber production due to their abundance in nature and their ability to form strong and durable fibers. These macromolecules provide the necessary properties for fibers, such as strength, flexibility, and durability, making them suitable for various textile applications. **

Enzymes are proteins because they are made up of long chains of amino acids, which are the building blocks of proteins. These amino acids are arranged in a specific sequence that gives each enzyme its unique structure and function. Proteins are well-suited for the role of enzymes because they can fold into complex three-dimensional shapes that allow them to interact with other molecules in specific ways. Lipids and other macromolecules do not have the same ability to form the diverse range of structures and active sites needed for enzymatic function. Therefore, proteins are the most suitable macromolecules for serving as enzymes in biological systems. **

The caricature of the summit conference in Helsinki shows the leaders of the United States and Russia, Donald Trump and Vladimir Putin, sitting at a table with Trump holding a puppet string attached to Putin. This caricature is a satirical representation of the perception that Trump is under the control or influence of Putin, suggesting that Putin is pulling the strings and manipulating Trump. The image reflects the controversy and speculation surrounding the relationship between the two leaders and the potential influence of Russia on the United States. **

A symposium is a formal gathering or meeting where experts in a particular field come together to discuss and exchange ideas on a specific topic. It is often organized as a series of presentations, panel discussions, and Q&A sessions, allowing participants to share their knowledge and insights with each other. Symposia are commonly held in academic and professional settings, providing a platform for networking, collaboration, and learning within a specific discipline or industry. **

"Der Kongress tanzt" is a German phrase that translates to "The Congress Dances" in English. The phrase originated from the Congress of Vienna in 1814-1815, where European diplomats and leaders gathered to reorganize Europe after the Napoleonic Wars. The phrase is a metaphor for the diplomatic and political maneuvering that took place during the Congress, likening it to a dance where participants carefully navigated their relationships and alliances. It reflects the complex and intricate nature of international diplomacy and negotiations during this historic event. **

A convention is a formal agreement or a set of accepted norms and practices that govern behavior in a particular context or industry. It is a customary way of doing things that is widely recognized and followed by a group of people. Conventions help to establish consistency, order, and predictability in social interactions or professional settings. They can vary across different cultures, societies, or fields of study. **

The G20 summit is a meeting of the leaders of the world's 20 largest economies, representing both developed and developing countries. The summit provides a platform for these leaders to discuss and coordinate on global economic issues, such as trade, finance, and development. It is an opportunity for countries to work together to address common challenges and promote global economic stability and growth. The G20 summit also serves as a forum for leaders to address pressing international issues, such as climate change, terrorism, and global health crises. **
