Atype of enzyme catalyzed chemical reaction that is very common in biology and involves joining building blocks monomers together to build a larger molecule known as polymer

condensation or dehydration synthesis

Explanation:

A condensation reaction can be described as a reaction in which two molecules combine to form a larger molecule. A water molecule is usually dispersed during this reaction.

For example, two amino acids join to form a protein. The bond formed between them is known as dipeptide bond.

Dehydration synthesis is also a reaction in which molecules via covalent bonds to form larger molecules. As water molecule is released during this process, this reaction is termed as dehydration synthesis.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
