Unit 3: Organic Compound Review

Front

What are lipids?

Back

Lipids are a group of organic compounds that include fats, oils, waxes, cholesterol, and hormones. They are hydrophobic (do not mix with water) and are important for energy storage and cell structure.

Front

What is the primary function of lipids in the body?

Back

The primary function of lipids is long-term energy storage. They provide more energy per gram than carbohydrates and are essential for various biological functions.

Front

What is a carbohydrate?

Back

Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. They are a primary source of energy for living organisms.

Front

What is the molecular formula for a carbohydrate?

Back

A common molecular formula for carbohydrates is Cn(H2O)n, where 'n' is the number of carbon atoms. An example is C4H8O4.

Front

Where is DNA located in eukaryotic cells?

Back

In eukaryotic cells, DNA is located in the nucleus, which is a membrane-bound organelle.

Front

What element is essential for organic compounds?

Back

Carbon is the essential element for organic compounds, as it can form stable bonds with many elements, including itself.

Front

What are the four main types of organic compounds?

Back

The four main types of organic compounds are carbohydrates, lipids, proteins, and nucleic acids.

Front

What are proteins made of?

Back

Proteins are made of amino acids, which are linked together by peptide bonds. They play crucial roles in the body, including structure, function, and regulation of tissues and organs.

Front

What is the role of nucleic acids?

Back

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

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats have no double bonds between carbon atoms and are typically solid at room temperature, while unsaturated fats have one or more double bonds and are usually liquid at room temperature.
