Biomolecules in Chemistry

What are the building blocks of carbohydrates?

• Proteins, vitamins, and minerals

• Monosaccharides, disaccharides, and polysaccharides

• Fatty acids, triglycerides, and cholesterol

• Amino acids, nucleotides, and lipids

Name the two types of carbohydrates.

• Primary carbohydrates and secondary carbohydrates

• Simple carbohydrates and complex carbohydrates

• Easy carbohydrates and difficult carbohydrates

• Basic carbohydrates and advanced carbohydrates

What is the function of lipids in the body?

• Lipids have no role in the body

• Lipids serve as a source of energy, help in the absorption of fat-soluble vitamins, provide insulation and protection for organs, and are essential for the structure and function of cell membranes.

• Lipids function as enzymes in the body

• Lipids are only used for energy storage

What are the main components of a triglyceride?

• Three fatty acid molecules and two glycerol molecules

• Two fatty acid molecules and one glycerol molecule

• Three fatty acid molecules and one glycerol molecule

• Four fatty acid molecules and one glycerol molecule

What are the functions of proteins in the body?

• Proteins are responsible for maintaining blood sugar levels

• Proteins help in the production of red blood cells

• Proteins function as neurotransmitters in the body

• The functions of proteins in the body include building and repairing tissues, producing enzymes and hormones, and serving as a source of energy.

What are the four levels of protein structure?

• Primary, Secondary, Tertiary, Quaternary

• A, B, C, D

• Red, Blue, Green, Yellow

• Basic, Advanced, Expert, Master

What are nucleic acids and their role in the body?

• Nucleic acids are primarily used for energy storage, not genetic information

• Nucleic acids are essential for the storage and transmission of genetic information, and they play a key role in protein synthesis and cell function.

• Nucleic acids have no role in protein synthesis or cell function

• Nucleic acids are only found in plants, not in the human body

Name the two types of nucleic acids.

• Carbohydrate and Fiber

• DNA and RNA

• Enzyme and Hormone

• Protein and Lipid

What are enzymes and their role in biochemical reactions?

• Enzymes are unstable and easily denatured, making them ineffective in speeding up biochemical reactions.

• Enzymes are only found in plants and have no role in biochemical reactions.

• Enzymes are inorganic molecules that inhibit biochemical reactions by increasing the activation energy required for the reaction to occur.

• Enzymes are biological molecules that act as catalysts to speed up biochemical reactions by lowering the activation energy required for the reaction to occur.

Explain the lock and key model of enzyme-substrate interaction.

• The lock and key model of enzyme-substrate interaction describes the specific and complementary fit between the enzyme's active site and the substrate.

• The lock and key model of enzyme-substrate interaction describes the random collision between the enzyme and substrate.

• The lock and key model of enzyme-substrate interaction involves the enzyme changing its shape to fit the substrate.

• The lock and key model of enzyme-substrate interaction explains the non-specific interaction between enzyme and substrate.
