For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Amino acids<\/strong> join to form <strong>proteins<\/strong>.<\/li>\n\n\n\n<li><strong>Nucleotides<\/strong> join to form <strong>nucleic acids<\/strong>.<\/li>\n\n\n\n<li><strong>Simple sugars<\/strong> (like glucose) link to form <strong>polysaccharides<\/strong> (like starch or cellulose).<\/li>\n<\/ul>\n\n\n\n<p>The chemical reaction responsible for polymer formation is known as <strong>dehydration synthesis<\/strong>, also called a <strong>condensation reaction<\/strong>. In this process, a water molecule (H\u2082O) is removed when two monomers are joined together. For example, when two amino acids link, the -OH group from one and the -H from another are removed, forming water and a <strong>peptide bond<\/strong>.<\/p>\n\n\n\n<p>This type of reaction is <strong>endergonic<\/strong>, meaning it <strong>requires energy input<\/strong> to proceed. In living organisms, this energy is typically provided by molecules like <strong>ATP (adenosine triphosphate)<\/strong>. For instance, during protein synthesis, ATP is used during translation to assemble amino acids into polypeptide chains.<\/p>\n\n\n\n<p>This energy requirement occurs because the formation of bonds in polymers is not energetically favorable by itself. The system must absorb energy to overcome the activation energy barrier and drive the formation of stable covalent bonds between monomers.<\/p>\n\n\n\n<p>In contrast, <strong>breaking down polymers<\/strong> (e.g., during digestion) is usually an <strong>exergonic<\/strong> process \u2014 it <strong>releases energy<\/strong> and often involves <strong>hydrolysis<\/strong> (adding water to break the bond).<\/p>\n\n\n\n<p>In summary, the synthesis of biological macromolecule polymers involves <strong>dehydration synthesis reactions<\/strong> that are <strong>endergonic<\/strong>, requiring energy input. This energy investment is vital for building the complex molecules necessary for life, including enzymes, genetic material, and structural components of cells.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What kind of reaction is in terms of energy input\/output in biological macrmolecules polymers The correct answer and explanation is: Correct Answer: The formation of biological macromolecule polymers involves a dehydration synthesis (condensation) reaction, which is an endergonic reaction (requires energy input).
