Why are all enzymes hormones, but all hormones are not enzymes?Why enzyme action is considered highly specific?What is the role of enzymes as a catalyst?Why are enzymes secreted in an inactive form?Explain how an enzyme speeds up a reaction as a catalyst.Enzymes are catalysts because they op...
Why can xylitol only participate in 3 enzyme-catalyzed biological reactions? Why is an enzyme considered a catalyst? Give two characteristics of catalysts. What is an active site? What is a substrate? What is a product? Describe how enzymes facilitate chemical reactions. Make a drawing or descri...
Describe the natural cycle of nitrogen from the atmosphere to biological organisms and back to the atmosphere. To what class of biomolecules do enzymes belong? Describe the methods that cells used to transport glucose into cells, and briefly discuss the biochemical reaction that ensures that glucose...
What are the properties of an enzyme that make it a good biological catalyst? Explain the functions of enzymes and enzyme inhibitors. Describe why scientists measure the initial rate of product formation in an enzyme catalyzed reaction. What would a protein enzyme do when mixed with a starc...
We produce over 100,000 different enzymes, each doing a unique task. 我们体内的酶分为两种,代谢酶和消化酶。人体合成超过10万种酶,每一种酶都承担着独一无二的作用。 11. Enzymes are the catalyst of every chemical reaction in our bodies. Without them, there can be no cellular division, immune...
Enzymes are the catalyst for the hundreds of thousands of chemical reactions that occur throughout the body. Cooked foods and dry convenience diets have been denatured and are devoid of enzymes and life promoting elements. While they may maintain life, they do not promote optimum health or ...
in the US is exploring the use of bacteria to precipitate carbon-capturing minerals from seawater, locking up the CO2. This work is based on a catalyst enzyme that is also being examined by scientists in China, who are looking at hot vents on the ocean floor for heat-resistant enzymes. ...
Why are enzymes important to the human body?Catalysts:Catalysts are substances that speed up the rate of a chemical reaction. They do this by lowering the energy barrier, called the activation energy, for a reaction to occur. In the process, the catalyst is not changed so it does not need...
The specificity of enzymes is necessary to control the metabolic reactions in the body. Every enzyme in the body is specialized in a particular function. Enzyme specificity reduces the chances of the formation of abnormal products in the body....
The process of DNA replication is an important one, and so must be checked during the checkpoint. Enzymes: An enzyme is a biological molecule that act as a catalyst for biological reactions. Enzymes are vital for life and also perform a variety of functions.A...
