By hydrolyzing starch into glucose

Describe the role of hydrolysis in the digestion of proteins.

It breaks down polypeptides into amino acids

It combines amino acids to form polypeptides

It converts proteins into nucleic acids

It synthesizes new proteins from amino acids

Compare the structures of saturated and unsaturated fatty acids.

Unsaturated fatty acids have double bonds; saturated do not

Saturated fatty acids have double bonds; unsaturated do not

Both have the same number of hydrogen atoms

Both have the same number of carbon atoms

Explain how the structure of nucleic acids enables their function in storing genetic information.

The sequence of nucleotides encodes genetic information

The double helix structure allows for energy storage

The sugar-phosphate backbone provides structural support

The presence of uracil allows for protein synthesis

Discuss the importance of protein folding in determining protein function.

Folding affects the protein's ability to catalyze reactions

Folding determines the sequence of amino acids

Folding is unrelated to protein function

Folding only affects the protein's solubility

Analyze the impact of dehydration synthesis on the formation of triglycerides.

It joins glycerol and fatty acids to form triglycerides

It breaks down triglycerides into glycerol and fatty acids

It converts triglycerides into phospholipids

It hydrolyzes triglycerides into energy

Evaluate the role of hydrolysis in the metabolism of carbohydrates.

It breaks down carbohydrates into simpler sugars for energy

It synthesizes carbohydrates from carbon dioxide and water

It converts carbohydrates into lipids for storage

It forms complex carbohydrates from simple sugars

Predict how a mutation in the nucleotide sequence of DNA might affect protein function.

It may alter the amino acid sequence, affecting protein function

It will have no effect on protein function

It will always result in a nonfunctional protein

It will only affect the protein's solubility

Design an experiment to test the effect of temperature on protein folding.

Compare the structural changes in proteins at different temperatures

Measure the solubility of proteins at different temperatures

Observe the rate of enzyme activity at various temperatures

Analyze the amino acid sequence of proteins at different temperatures

Assess the significance of lipid structure in the formation of cell membranes.

Lipids form flexible bilayers that create a barrier

Lipids form rigid structures that provide support

Lipids dissolve in water to form membranes

Lipids are not involved in membrane formation

Explain how the structure of carbohydrates relates to their function as energy sources.

Their simple sugars are easily broken down for quick energy

Their complex structure makes them difficult to break down

Their structure allows them to store large amounts of energy

Their structure prevents them from being used as energy

Identify the role of dehydration synthesis in the formation of nucleic acids.

It joins nucleotides to form DNA and RNA

It breaks down nucleotides into smaller units

It converts nucleic acids into proteins

It hydrolyzes nucleic acids into energy

Discuss how hydrolysis is involved in the breakdown of lipids.

It breaks down triglycerides into glycerol and fatty acids

It combines fatty acids to form triglycerides

It converts lipids into carbohydrates

It synthesizes new lipids from fatty acids

Analyze the relationship between protein structure and enzyme specificity.

The three-dimensional structure of proteins determines enzyme specificity

Enzyme specificity is unrelated to protein structure

Enzyme specificity is determined by the protein's amino acid sequence alone

Enzyme specificity is determined by the protein's solubility
