Adobe PDF documents can be multi-page documents or single-page documents, and can include an array of graphics and text in an assortment of colors.
Which fact is most important in explaining how enzymes speed reactions? Very low potential energy tends to make molecules unstable. High-energy collisions are less common than low-energy collisions. It takes less energy to break a hydrogen bond than a covalent bond. Large molecules collide more energetically than small molecules. Every reaction step adds to the time required for the overall reaction. Study Enzyme Activity.
Enzymes are large molecules that speed up the chemical reactions inside cells. Each type of enzyme does on specific job. Enzymes are a type of protein, and like all proteins, they are made from long chains of different amino acids. Biological catalysts Enzymes are soluble protein molecules that can speed up chemical reactions in cells. These reactions include respiration, photosynthesis and making new proteins. For this reason enzymes are sometimes called biological catalysts. Enzymes speed up (catalyse) chemical reactions occurring inside and outside of living cells.
