What is dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction where two molecules are joined together by the removal of a water molecule, forming a covalent bond.

Front

What is hydrolysis?

Back

Hydrolysis is a chemical reaction that involves the breaking down of a compound by the addition of water, cleaving covalent bonds.

Front

What is the role of water in dehydration synthesis?

Back

In dehydration synthesis, water is removed to form a covalent bond between monomers.

Front

What is the role of water in hydrolysis?

Back

In hydrolysis, water is added to break the covalent bond in a compound.

Front

What is capillary action?

Back

Capillary action is the ability of water to move through narrow spaces against gravity, due to cohesion and adhesion forces.

Front

What is the electron-dot structure of carbon?

Back

The electron-dot structure of carbon has 4 dots, representing its four valence electrons.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the difference between dehydration synthesis and hydrolysis?

Back

Dehydration synthesis combines molecules by removing water, while hydrolysis breaks down molecules by adding water.

Front

What is the significance of enzymes in biochemical reactions?

Back

Enzymes are catalysts that speed up biochemical reactions by lowering the activation energy required.

Front

What is the importance of water in biological systems?

Back

Water is essential for life; it acts as a solvent, participates in chemical reactions, and helps regulate temperature.
