AP Biology Semester 1 Final Review

Front

What is a polar covalent bond?

Back

A type of bond where electrons are shared unevenly between two atoms, resulting in partial positive and negative charges.

Front

What is hydrolysis?

Back

A chemical process that involves the addition of water to break down compounds, such as breaking the bond between monosaccharides in carbohydrates.

Front

What is dehydration synthesis?

Back

A chemical reaction that involves the removal of water to form a bond between two molecules, such as linking amino acids to form proteins.

Front

What type of bond is formed when electrons are transferred from one atom to another?

Back

Ionic bond.

Front

Which element is more electronegative, Oxygen (O) or Beryllium (Be)?

Back

Oxygen (O) is more electronegative.

Front

What is the primary function of carbohydrates in living organisms?

Back

To provide energy and serve as structural components.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is the difference between a monosaccharide and a polysaccharide?

Back

Monosaccharides are single sugar molecules, while polysaccharides are long chains of monosaccharides linked together.

Front

What is an example of a polar molecule?

Back

Water (H2O) is an example of a polar molecule due to its bent shape and uneven distribution of charge.

Front

What is the significance of electronegativity in chemical bonding?

Back

Electronegativity determines how strongly an atom attracts electrons in a bond, influencing bond type and molecular properties.
