Enzymes and Macromolecules Practice Questions 20241217 Part 2

Front

What are lipids?

Back

Lipids are a class of macromolecules that include fats, oils, and waxes. They are hydrophobic and play key roles in energy storage, insulation, and cellular structure.

Front

What is the optimum temperature for enzyme activity?

Back

The optimum temperature is the temperature at which an enzyme's activity is at its highest. For many enzymes, this is around 37-40 degrees Celsius.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What class of macromolecules does sugar belong to?

Back

Sugar belongs to the class of macromolecules known as carbohydrates.

Front

What is the primary function of nucleic acids?

Back

The primary function of nucleic acids, such as DNA and RNA, is to store and transmit genetic information.

Front

What are the main types of macromolecules?

Back

The main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the role of enzymes in biological reactions?

Back

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

Front

What are carbohydrates?

Back

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

Front

What are proteins made of?

Back

Proteins are made of amino acids, which are linked together by peptide bonds.

Front

What is the difference between saturated and unsaturated fats?

Back

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