Which of the following are examples of hydrolysis reactions?
A strand of DNA is broken down into individual nucleotides. A sugar is broken down into fructose and glucose molecules.
How do cells obtain energy from glucose?
By breaking its bonds and using the energy they store to build ATP
What are the four categories of macromolecules?
Carbohydrates, lipids, proteins, and nucleic acids
Match each macromolecule to its appropriate function.
Carbohydrates-molecules are broken down to make ATP, while larger molecules may store energy or may play a structural role Simpler molecules are broken down to make ATP, while larger molecules may store energy or may play a structural role Lipids-key components of cell membranes; Also function as hormones and in energy storage Are key components of cell membranes; Also function as hormones and in energy storage Proteins-ChoicePlay a key role in cell structure and carry out diverse array of cellular functions Play a key role in cell structure and carry out diverse array of cellular functions Nucleic acids Nucleic acids-ChoiceFunction in storage of, and access to, genetic information Function in storage of, and access to, genetic information
Which of the following atoms form nonpolar covalent bonds with carbon?
Carbon Hydrogen
Which of the following describes the relationship between condensation reactions and dehydration synthesis?
Condensation reactions and dehydration synthesis occur when two or more molecules combine to form a larger molecule. Dehydration synthesis is a specific type of condensation reaction involving the loss of a water molecule.
