Unit 2 Biochemistry

Abigail, Henry, and Michael are in a biology class. Their teacher asks them, 'If you were to build a protein in a lab, what would you use as your building blocks?'

• Nucleic acids

• Amino acids

• Carbohydrates

• Fatty acids

Rohan, Hannah, and Avery are studying for their biology exam. They come across a question about the building blocks (monomers) of carbohydrates. What would be the correct answer?

• Monosaccharides

• Nucleotides

• Amino acids

• Fatty acids

Abigail, Lily, and Aiden are working on a science project about macromolecules (polymers). They discovered that enzymes are examples of which of these macromolecules?

• Carbohydrates

• Lipids

• Nucleic acids

• Proteins

Henry, Aiden, and Michael are planning to make homemade candles. They are discussing the materials they need. They know that oils, waxes, and phospholipids are examples of these macromolecules (polymers). What are these macromolecules called?

• Nucleic acids

• Lipids

• Carbohydrates

• Proteins

Hannah, Abigail, and Luna are working on a science project about macromolecules (polymers). They found that Deoxyribonucleic acids (DNA) and ribonucleic acids (RNA) are examples of which type of these macromolecules?

• Proteins

• Lipids

• Carbohydrates

• Nucleic acids

During a biology class, Benjamin, James, and Arjun were discussing the structure of DNA. They were trying to identify the building blocks for nucleic acids. What did they conclude?

• Lipids

• Carbohydrates

• Proteins

• Nucleotides

During a biology class, Benjamin, Kai, and Aria were discussing the process of digestion. They learned that when they eat a sandwich, a protein in their saliva known as salivary amylase begins to break down the starch in the bread into smaller chains of glucose. They were curious to know, what type of substance is this salivary amylase?

• Hormone

• Vitamin

• Mineral

• Enzyme

Maya, Scarlett, and Charlotte are studying DNA samples. In one of the samples, they found that 30% of the nitrogenous bases are Thymine (T). They are curious to know what percentage of the nitrogenous bases in the sample are Guanine (G).

• 50%

• 20%

• 30%

• 40%

James, Scarlett, and Daniel are studying for their biology exam. They come across a question about the composition of their hair and feathers of their pet bird. They found out that keratin is a protein found in both. Which of the following elements is most abundant in keratin?

• Hydrogen

• Carbon

• Oxygen

• Sulfur

Mia, Arjun, and Jackson are having a discussion about the high amount of the carbohydrate lactose in milk that they drink every day. They are curious to know, what is the basic structure of lactose?

• two fatty acids joined to a phosphate group

• A chain of amino acids in a helix (twisted) shape

• a chain of alternating sugar and phosphate groups

• two monosaccharides joined together
