A pigment solution contains compound A with 4 polar groups and compound B with 2 polar groups. You plan to separate these compou
Karolina [17]

The more polar A compound moves ahead of the less polar B compound.

Explanation:

The analytical process that involves the separation of colored substance or chemicals is named as paper chromatography, a replacement of thin-layer chromatography. In this method, there is the use of two solvents and rotation of paper at 90^0. It helps in isolating two complex compounds of equal polarity.

A non-polar mixture of solvent is required in the mobile phase of this method. In accordance with the retention factor of this process, the more polar compound A will go further than compound B as the solvent is non-polar.

During transcription, enzymes bind to a molecule of DNA. Then, the enzymes unwind and separate the DNA's double helical strands.

How do enzymes influence the amount of activation energy needed?
ser-zykov [4K]

What your cells have to help overcome a problem of high activation energy are called enzymes. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.

Enzymes make things easier for your cells to work properly and help chemical reactions occur. There are hundreds of different kinds of enzymes in your cells, which all participate in different types of reactions. Enzymes can break molecules apart, build or add molecules, and even rearrange them.

In lowering the activation energy of a reaction, enzymes decrease the barrier to starting a reaction. It's important to note, however, that the change in energy remains the same between the start and end of a chemical reaction.
