Answer:

Exergonic reaction

Explanation:

A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.

An exergonic reaction owing to the negative free energy change is a spontaneous reaction.

The energy that is released in the exergonic reaction is usually observed in the form of heat and light.

The energy is released due to the breaking of the chemical bonds.

Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.

exis [7]

Answer:

EtBr inserts between the stacked bases in the DNA double helix.

Explanation:

EtBr is used for visualizing DNA bands as it fluoresces under the UV illumination.
EtBr is an aromatic compound that is capable of inserting itself between the stacked bases of the DNA double helix.
The hydrophobic environment around the base pairs where the EtBr intercalates is responsible for the fluorescence. As the EtBr molecule intercalates between these base pairs the cation of EtBr sheds the water molecules associated with it and this causes it to fluoresce under UV light as water is a quencher of fluorescence.
