Unit 3a Energy Flow CP

Front

What are nucleotides?

Back

Nucleotides are the monomers that make up nucleic acids, which are essential macromolecules for storing and transmitting genetic information.

Front

What macromolecule do animals primarily use to store excess energy?

Back

Animals store most of their excess energy reserves as fat because it provides twice as much energy per gram compared to carbohydrates.

Front

What is a catalyst?

Back

A catalyst is a substance that decreases the activation energy needed for a chemical reaction, thereby increasing the reaction rate without being consumed in the process.

Front

What role do lipids play in the body?

Back

Lipids cushion and protect organs, serve as energy reserves, and are important components of cell membranes.

Front

What type of macromolecule is glucose?

Back

Glucose is a type of carbohydrate, which is a primary source of energy for cells.

Front

Define macromolecule.

Back

Macromolecules are large, complex molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the primary function of carbohydrates?

Back

The primary function of carbohydrates is to provide energy for the body, as well as to serve as structural components in cells.

Front

How do proteins function in the body?

Back

Proteins serve various functions including acting as enzymes, providing structural support, transporting molecules, and facilitating communication between cells.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids, which link together in specific sequences to form polypeptides.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats contain no double bonds between carbon atoms, making them solid at room temperature, while unsaturated fats contain one or more double bonds, making them liquid at room temperature.
