- Q2An advertisement for a health supplement for dogs claims to build lean muscle and strengthen tendons and ligaments, as well as provide energy. Which two biomolecules must the supplement contain to provide these benefits?ipids and nucleic acidsProteins and carbohydratesCarbohydrates and lipidsNucleic acids and carbohydrates60sBIOL.9a
- Q3Two biomolecules are shown. Which of the following best describes these biomolecules?Molecule X and Molecule Y are both carbohydrates.Molecule X is a carbohydrate, and Molecule Y is a nucleic acid.Molecule X and Molecule Y are both nucleic acids.Molecule X is a nucleic acid, and Molecule Y is a carbohydrate.60sBIOL.9a
- Q4Students were given a list of seven elements and asked to identify the four elements that are most abundant in biomolecules. Which table correctly identifies the four most-abundant elements in biomolecules?30sBIOL.9a
- Q5Some foods that are rich in complex carbohydrates can be difficult to digest. Gas often forms as the foods are slowly digested by bacteria in the large intestine. The advertisement is for a nutritional supplement that prevents intestinal gas. Which of the following represents evidence that could be used to support the claims about this product?Some nutritional supplements provide vitamins and minerals that are missing from a person's diet. These types of nutritional supplements contain important nutrients that reduce the risk of malnutritionSome nutritional supplements add beneficial bacteria to a person's diet. These bacteria populate the stomach and prevent carbohydrate digestion.Consuming enzymes specific for carbohydrate digestion helps the body digest complex carbohydrates more quickly in the stomach and small intestineComplex carbohydrates are found in vegetables and grains, which are good sources of fiber, vitamins, antioxidants, and minerals. Vegetables and grains are known to reduce the risk of heart disease.30sBIOL.9c
- Q6Proteins and carbohydrates have many functions in the body of an organism. Specific proteins and carbohydrates perform specific tasks. Information about a protein and a carbohydrate is given below. How are ferritin and glycogen similar in their primary functions for an organism?Both support the structure of the organismBoth store materials needed by the organismBoth store information for the organismBoth store energy used by the organism30sBIOL.9a
- Q7Four different nucleotides are used as building blocks of DNA. Which of the following can be used to distinguish one nucleotide from another?The shape of the deoxyribose sugarThe type of fatty acidThe nitrogenous baseThe length of the phosphate group30sBIOL.9a
- Q8The complex carbohydrates pictured below are made by linking molecules of glucose. In all three complex carbohydrates, the subunits of glucose are bonded together differently. Because they have different structures, they most likely -form different proteinsperform different functionscarry different nucleotidescontain different chemical elements30sBIOL.9a
- Q9A student preparing for a hike wants to pack a snack that has biomolecules that provide quickly available energy but few excess calories. Which nutrition label lists the best combination of biomolecules that provide quickly available energy while providing the fewest calories from other types of biomolecules?30sBIOL.9a
- Q10A segment of DNA is represented in the illustration. How is information for a specific protein carried on the DNA molecule?As a pattern of phosphates and sugarsAs a sequence of nucleotidesIn the ratio of adenines to thyminesIn the double-helix shape of the condensed chromosome30sBIOL.6a
- Q11The differences between two molecules include the type of sugar that forms a section of the molecules and the identity of one of the four nitrogenous bases that make up another section of the molecules. These two molecules are -proteinscomplex carbohydrateslipidsnucleic acids30sBIOL.9a
- Q12Carbohydrates are more easily metabolized than lipids. However, on a gram-for-gram basis lipids provide cells with more -structureproteinsenergynitrogen30sBIOL.9a
- Q13Which of the following biomolecules typically contains both nitrogen and phosphate?LipidProteinCarbohydrateNucleic acid30sBIOL.9a
- Q14Enzymes are proteins that help increase the rate of chemical reactions inside cells. These proteins are composed of many simpler molecules called amino acids. Which of the following suggests that the shape of an enzyme determines the enzyme's function?Enzymes can be found in all life-formsEnzymes are specific to a substrate.Enzymes are activated by neighboring moleculesEnzymes can operate in a wide range of conditions30sBIOL.9c
- Q15Proteins and polysaccharides are polymers. These polymers are formed by dehydration synthesis. Which statement correctly identifies a difference in the structure of proteins and polysaccharides?Only proteins can be large molecules with thousands of subunitsOnly polysaccharides are comprised of repeating units of cytosine, adenine, guanine, and thymineOnly polysaccharides can be folded and twisted to very specific shapesOnly proteins are formed from amino acids joined by peptide bonds30sBIOL.9a
