Answer the following question given this paragraph: An enzyme is an organic catalyst produced by a living cell. Enzymes are such powerful catalysts that the reactions they promote occur rapidly at body temperature. Without the help of enzymes, these reactions would require high temperatures and long reaction times. The molecule or molecules on which an enzyme acts are called its substrates. An enzyme has an active site where its substrate or substrates bind to form an enzymesubstrate complex. The reaction occurs, and product is released:. Q: An enzyme is an organic catalyst produced by what? Choices: - DNA - the liver - amino acid - living cell A:
(Answer)
living cell

Ques:Answer the following question given this paragraph: Tremetol, a metabolic poison found in the white snake root plant, prevents the metabolism of lactate. When cows eat this plant, it is concentrated in the milk they produce. Humans who consume the milk become ill. Symptoms of this disease, which include vomiting, abdominal pain, and tremors, become worse after exercise. Why do you think this is the case? Alcohol Fermentation Another familiar fermentation process is alcohol fermentation ( Figure 7.15) that produces ethanol, an alcohol. The first chemical reaction of alcohol fermentation is the following (CO2 does not participate in the second reaction):. Q: Tremetol, a metabolic poison found in the white snake root plant, prevents the metabolism of what? Choices: - sugars - sodium - lipids - lactate A:

Ans:lactate
Question: Answer the following question given this paragraph: High summer temperatures on the desert create high winds and monsoon storms. Strong winds in the desert can pick up dust and blow it around. A dust storm known as a haboob ( Figure below ) forms in the downdrafts on the front of a thunderstorm. Q: What causes high winds and monsoon storms in the desert? Choices: - moderate spring temperature - and-12 summer temperature - low winter temperature - high summer temperature A:
