Answer:
In 1953, scientist Stanley Miller performed an experiment that may explain what occurred on primitive Earth billions of years ago. He sent an electrical charge through a flask of a chemical solution of methane, ammonia, hydrogen and water. This created organic compounds including amino acids.
Making amino acids is tricky, even in the laboratory. We know amino acids exist in some kinds of meteorites and interplanetary dust particles. When they rain down on a planet's surface, they import the possible building blocks of life, not necessarily life itself. Scientists think that along the way, there must have been a crucial step that turned atoms into organisms, but they still don't know what it is.
Answer:
<h3>A) Enzymes are highly specific protein catalysts</h3>
Explanation:
- Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
- Enzymes have an active site by which it binds to substrate at that specific site.
- Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
- Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.
I’m sorry if i get this wrong but I’m guessing it’s either 2 and 3 or 1 and 4
