LIFE SCIENCE

Detailed explanation-1: -They act as catalysts, which means that they make biochemical reactions happen faster than they would otherwise. Without enzymes, those reactions simply would not occur or would run too slowly to sustain life.

Detailed explanation-2: -In the absence of enzymatic catalysis, most biochemical reactions are so slow that they would not occur under the mild conditions of temperature and pressure that are compatible with life.

Detailed explanation-3: -Without them, your body can’t break foods down so that nutrients can be fully absorbed. A lack of digestive enzymes can lead to a variety of gastrointestinal (GI) symptoms. It can also leave you malnourished, even if you eat a nutritious diet.

Detailed explanation-4: -Enzymes bind substrates at key locations in their structure called active sites. They are typically highly specific and only bind certain substrates for certain reactions. Without enzymes, most metabolic reactions would take much longer and would not be fast enough to sustain life.

Detailed explanation-5: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.
