WebEnzymes are biological catalysts. Enzymes are the catalysts involved in biological chemical reactions. They are the “gnomes” inside each one of us that take molecules like nucleotides and align them together to create DNA, or amino acids to make proteins, to name two of … WebThe hydrogen bonds will start to break apart at higher temperature. The hydrogen bonds help give the protein or enzyme is folded shape. With this increase in temperature, the … WebApr 9, 2024 · As discussed earlier, the shape of a protein is critical to its function. For example, an enzyme can bind to a specific substrate at a site known as the active site. If this active site is altered because of local changes or changes in overall protein structure, the enzyme may be unable to bind to the substrate. port wentworth ga utilities
