Question

question 4 what are compounds that have the same molecular formulas but different structures and different molecules? isotope isomer monomer amino acid question 5 what substance is removed during a condensation reaction? polymer carboxyl group hydrocarbon water question 6 what carbohydrate energy storage molecule is found in animal liver and muscle cells? glycogen cellulose glucose starch

Explanation:

• Question 4: Isomers have the same molecular formula but different structures. Isotopes are variants of an element with different numbers of neutrons. Monomers are small molecules that can form polymers. Amino - acids are the building blocks of proteins.
• Question 5: In a condensation reaction, water is removed when two molecules combine to form a larger molecule. Polymers are large molecules formed by monomers. A carboxyl group is a functional group. Hydrocarbons are compounds composed of carbon and hydrogen.
• Question 6: Glycogen is the carbohydrate energy - storage molecule in animal liver and muscle cells. Cellulose is a structural component in plant cell walls. Glucose is a monosaccharide and a source of energy. Starch is a plant energy - storage molecule.

Answer:

Question 4: Isomer
Question 5: Water
Question 6: Glycogen
