AP Biology Unit 1 Review

Front

What are peptide bonds?

Back

Peptide bonds are the covalent bonds that join amino acids together in a protein.

Front

What property of water allows it to regulate temperature?

Back

The high specific heat of water, which results from its polarity and hydrogen bonding, allows it to retain temperature.

Front

What is a characteristic of unsaturated fats?

Back

Unsaturated fats have one or more double bonds in the fatty acid chain.

Front

What is hydrolysis?

Back

Hydrolysis is a chemical process that involves the digestion of larger molecules into their monomers, such as breaking down sucrose into glucose and fructose.

Front

Which statement about carbon is false?

Back

Carbon has the capacity to form polar covalent bonds with hydrogen.

Front

What is the role of hydrogen bonds in nucleic acids?

Back

Hydrogen bonds form between nitrogen bases, stabilizing the structure of nucleic acids like DNA.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats contain only single bonds between carbon atoms, while unsaturated fats contain one or more double bonds.

Front

What is the significance of carbon's ability to form four covalent bonds?

Back

Carbon's ability to form four covalent bonds allows it to create complex molecules and extensive carbon skeletons.

Front

What is the process of dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction that joins two molecules by removing a water molecule, forming a covalent bond.

Front

What is the function of enzymes in biological reactions?

Back

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