Front

What are unsaturated fats?

Back

Unsaturated fats are fats that contain one or more double bonds in their fatty acid chains, making them liquid at room temperature and more common in plants than in animals.

Front

What is the molecular formula for glucose?

Back

The molecular formula for glucose is C6H12O6.

Front

What is the relationship between structural isomers?

Back

Structural isomers are compounds that have the same molecular formula but different structural arrangements of atoms.

Front

What happens to DNA when treated with enzymes that catalyze hydrolysis?

Back

The phosphodiester linkages of the polynucleotide backbone would be broken, leading to the breakdown of DNA into its nucleotide components.

Front

What are isotopes?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction that involves the removal of water to join two molecules together, commonly seen in the formation of polymers.

Front

What is the significance of double bonds in fatty acids?

Back

Double bonds in fatty acids create kinks in the chain, preventing tight packing and resulting in liquid fats at room temperature.

Front

What are the components of a nucleotide?

Back

A nucleotide consists of a phosphate group, a sugar (deoxyribose or ribose), and a nitrogenous base.

Front

What is the role of enzymes in biological reactions?

Back

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

Front

What is a polymer?

Back

A polymer is a large molecule made up of repeating subunits called monomers, linked together by covalent bonds.
