Biological Molecules Quiz BWHS

What type of biological molecule is shown? HINT: Made of amino acids.

• carbohydrate

• lipid

• protein

• nucleic acid

Answer explanation

The question hints that the molecule is made of amino acids, which are the building blocks of proteins. Therefore, the correct answer is protein, as carbohydrates, lipids, and nucleic acids are composed of different types of molecules.

What type of biological molecule is shown?

• carbohydrate

• lipid

• protein

• nucleic acid

Answer explanation

The molecule shown is a lipid, characterized by its hydrophobic nature and structure, which typically includes long hydrocarbon chains or rings. Lipids are essential for cell membrane formation and energy storage.

What type of biological molecule is shown?

• carbohydrate

• lipid

• protein

• nucleic acid

Answer explanation

The molecule shown is a carbohydrate, which is characterized by the presence of carbon, hydrogen, and oxygen in a specific ratio. Carbohydrates serve as a primary energy source and include sugars and starches.

Which biological molecule contain carbon, hydrogen, and oxygen in a 1:2:1 ratio?

• proteins

• carbohydrates

• lipids

• nucleic acids

Answer explanation

Carbohydrates are the biological molecules that contain carbon, hydrogen, and oxygen in a 1:2:1 ratio, which is characteristic of their structure. Proteins, lipids, and nucleic acids do not follow this specific ratio.

What type of molecule is sucrose?

• disaccharide

• monosaccharide

• .

• .

Answer explanation

Sucrose is a disaccharide, which means it is composed of two monosaccharides: glucose and fructose. This classification distinguishes it from monosaccharides, which are single sugar units.

What type of molecule is glucose?

• monosaccharide

• disaccharide

• .

• .

Answer explanation

Glucose is a monosaccharide, which is the simplest form of carbohydrates. It consists of a single sugar unit, unlike disaccharides that are made of two sugar units. Therefore, the correct answer is monosaccharide.

The term "Disaccharides" means

• sugar that contains one glucose

• Sugar that contains two glucose

• Sugar that contains more than two glucose.

Answer explanation

The term 'Disaccharides' refers to sugars composed of two monosaccharides, which can include two glucose molecules or one glucose and another sugar. Therefore, the correct choice is 'Sugar that contains two glucose'.

Fatty acids is the building blocks of ______________

• lipids
• carbohydrates

• proteins

• Nucleic Acid

Answer explanation

Fatty acids are the fundamental components of lipids, which include fats, oils, and other related substances. Therefore, the correct answer is 'lipids'.

What Biological Molecules is responsible for muscle formation?

• Carbohydrates

• Lipids

• Protein

• Nucleic Acids

Answer explanation
