Which macromolecule is primarily responsible for storing genetic information?

• Carbohydrates

• Proteins

• Nucleic acids

• Lipids

What property of water allows it to transport nutrients effectively?

• Cohesion and adhesion

• Neutral pH

• High density

• Low boiling point

How does pH affect enzyme activity?

• It increases the enzyme's size

• It alters the enzyme's shape

• It has no effect on enzymes

• It changes the enzyme's color

What is the role of ATP in cells?

• It provides immune defense

• It stores genetic information

• It acts as a structural component

• It serves as the energy currency

Why is enzyme specificity important?

• It ensures enzymes only catalyze specific reactions

• It allows enzymes to work on multiple substrates

• It enables enzymes to function without substrates

• It makes enzymes resistant to temperature changes
