What is the difference between saturated and unsaturated fats?

Back

Saturated fats tend to be solid at room temperature, while unsaturated fats are liquid at room temperature.

What are the components of a nucleic acid monomer?

Back

A nucleic acid monomer consists of a pentose sugar, a nitrogenous base, and a phosphate group. Amino acids are not part of nucleic acid monomers.

Front

What type of protein structure involves R group bonding?

Back

The tertiary structure of a protein involves R group bonding to form its final three-dimensional shape.

Front

Which macromolecule contains phosphorus?

Back

Nucleic acids are the macromolecules that contain phosphorus.

Front

What are the results of hydrogen bonding in water molecules?

Back

Hydrogen bonding in water molecules results in cohesion, adhesion, and surface tension. It does not result in dissolving fats.

Front

Define saturated fats.

Back

Saturated fats are fats that have no double bonds between carbon atoms, leading to a straight structure that allows them to pack closely together.

Front

Define unsaturated fats.

Back

Unsaturated fats contain one or more double bonds between carbon atoms, resulting in a bent structure that prevents tight packing.

Front

What is the primary structure of a protein?

Back

The primary structure of a protein is the linear sequence of amino acids linked by peptide bonds.

What is the secondary structure of a protein?

Back

The secondary structure of a protein refers to local folded structures that form within a polypeptide due to hydrogen bonding, such as alpha helices and beta sheets.

What is the role of phospholipids in cell membranes?

Back

Phospholipids form the bilayer of cell membranes, with hydrophilic heads facing outward and hydrophobic tails facing inward, creating a barrier.
