Which of the following statements are correct about macromolecules? (choose all correct responses) macromolecules are large molecules which are made by chemically bonding smaller molecules (monomers or subunits) together carbohydrates, proteins, lipids and nucleic acids are all examples of organic macromolecules because they are all large and they all contain carbon because all the energy is tied up in the bonds, macromolecules have very little energy in them enzymes can break macromolecules down into their respective subunits or monomers.

Every compound can be represented by a chemical formula. a chemical formula is the set of symbols showing the elements that make up a compound and their proportions. water’s chemical formula is h 2 2 o. that means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. a molecule is a group of two or more atoms bonded together. molecules can range in size from two to thousands of atoms. a molecule of a compound is the smallest unit of that compound. every molecule of water has all the physical and chemical properties of water. that’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! which of the following is a true statement? a every molecule of the same compound will have different properties. b every molecule of a compound has the same proportion of elements. c molecules can be physically separated into smaller units of a compound. d molecules cannot be represented by chemical formulae.
