Unit 1: Macromolecules & Enzymes & Cells

Front

What are lipids?

Back

Lipids are a group of macromolecules that include fats, oils, and waxes. They are hydrophobic and play key roles in energy storage, insulation, and forming cell membranes.

Front

What are the monomers of carbohydrates?

Back

Monosaccharides are the monomers of carbohydrates. They are simple sugars like glucose and fructose.

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a simple, unicellular organism that lacks a nucleus and membrane-bound organelles. Bacteria are examples of prokaryotic cells.

Front

What is the function of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are responsible for storing and transmitting genetic information.

Front

What are examples of nucleic acids?

Back

DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are examples of nucleic acids.

Front

What is the primary function of proteins?

Back

Proteins serve various functions including acting as enzymes, structural components, and signaling molecules.

Front

What are carbohydrates?

Back

Carbohydrates are macromolecules made up of sugar molecules. They are a primary source of energy for living organisms.

Front

What is the role of enzymes in biological processes?

Back

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

Front

What is the structure of a lipid?

Back

Lipids are composed of long hydrocarbon chains or rings, making them hydrophobic. They can be saturated or unsaturated based on the presence of double bonds.

Front

What is the difference between saturated and unsaturated fats?

Back

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