All organic compounds contain what element ? User: Why is water important for a cell? User: DNA contains instructions for making what? User: Enzymes are important because why>
Weegy: Enzymes are one of the most essential elements in our body. Enzymes are more important than the air you breathe, the water you drink, and the food you eat. [ Why is this? Enzymes are required for your body to function properly because without enzymes you wouldn't be able to breathe, swallow, drink, eat, or digest your food. To do all of these things, your body needs some help. You must have enzymes to help perform these tasks. Enzymes are an absolute necessity to live. Enzymes are your body's workers. They are responsible for constructing, synthesizing, carrying, dispensing, delivering, and eliminating the many ingredients and chemicals our body uses in its daily business of living. Your body makes enzymes. When you were young, you had an abundant supply of enzymes. You felt great. Your energy level seemed never ending. You had "enzymes to burn" which kept you running at tip top efficiency. As time goes by, you SLOWLY begin to lose this efficiency. For years you don't even notice the changes. But then you are less able to eat the spicy foods you love or less able to recover as quickly from the aches and pains of weekend sports. This reduced vitality and stamina can signal a weakened and compromised body. You’re running low on the enzymes you need to fuel your life. The process of depleting your enzymes is a slow one, and most likely you didn't notice your energy and vitality disappearing until one day something you once loved to do was suddenly too much work. You aren't getting too old to enjoy life, you are running out of enzymes that would ensure you the energy you need to enjoy life. You simply need to restore your enzyme potential. ] User: how do you restoe them? Weegy: There is much you can do to combat your waning enzyme potential. The sooner you start, the quicker you begin to restore and extend the vitality you once had. [ If you still think you have it, you might be surprised what you have ever so slowly lost without knowing it until you ... (More)
