What is the action of a catalyst

Chemistry
1 answer:
AfilCa [17]2 years ago
8 0

Answer: A catalyst is a substance that speeds up the rate of a chemical reaction without being used up and remains chemically unchanged itself .

Explanation: For a reaction to take place the particles must collide with enough energy for bonds to break and reaction to occur .

BUT when a catalyst is present the reactants are able to react in a way that requires less energy ,leading to more successful collision so the reaction speeds up without the chemical composition of the catalyst being affected

NOTE: the catalyst must be chosen to suit the particular reaction

The nucleus represents a major evolutionary transition. As a consequence of separating translation from transcription many new functions arose, which likely contributed to the remarkable success of eukaryotic cells. Here we will consider what has recently emerged on the evolutionary histories of several key aspects of nuclear biology; the nuclear pore complex, the lamina, centrosomes and evidence for prokaryotic origins of relevant players.
