biological molecules

• What are biological molecules primarily used for in the body?

  They can be broken down to fuel respiration.
• What elements make up carbohydrates?

  Carbon, hydrogen, and oxygen.
• What are monosaccharides?

  They are the smallest units of carbohydrates, simple sugars like glucose or fructose.
• How can monosaccharides be combined?

  They can be joined together in long chains to form polymers.
• What are examples of large, complex carbohydrates?

  Starch and glycogen.
• What happens to polymer molecules in carbohydrates?

  They can be broken down back into simple sugars.
• Where in the body are carbohydrates digested?

  In the mouth and small intestine.
• What are proteins made up of?

  Long chains of monomers called amino acids.
• What atoms do amino acids contain?

  Carbon, nitrogen, hydrogen, and oxygen.
• Where are proteins broken down in the body?

  In the stomach and small intestine.
• What are lipids made from?

  Glycerol and three fatty acids.
• Why are lipids not considered polymers?

  They do not form a long chain of repeating units.
• What atoms do lipids contain?

  Carbon, hydrogen, and oxygen.
• Where are lipids broken down in the body?

  In the small intestine.
• What is the procedure to test for sugars?

  • Use Benedict's reagent.
• How is starch tested for?

  • Use iodine.
• What test is used for lipids?

  • Use the emulsion test.
• What test is used for proteins?

  • Use the Biuret test.
• What is the Anger Test?

  It involves annoying the test subject to see if anger is present.
