5 Questions
Match the macromolecule type with its primary function:
Carbohydrates = Give us energy Proteins = Act as enzymes and do much of the work of the cell Nucleic Acids = Genetic information of the cell Lipids = Store energy and create cell membranes
Match the macromolecule type with its monomer:
Carbohydrates = Monosaccharides Proteins = Amino acids Nucleic Acids = Nucleotides Lipids = Long fatty acids
Match the following terms with their definitions:
Monomer = Molecule made of one unit Polymer = Molecule made of two or more units Bond = Energy that holds atoms and molecules together Enzymes = Catalysts that speed up chemical reactions by lowering activation energy
Match the following scientific method terms with their definitions:
Independent variable = The changed or manipulated variable, what you are testing in an experiment Dependent variable = The measured variable, what you record, it's what you see in your results Controlled Variables = All the other variables that you don't change in an experiment Controlled experiments = Experiments that use only one variable (the independent variable) changed at a time
Match the following terms with their descriptions:
Enzymes = Proteins that act as catalysts and end in -ase Catalysts = Substances that speed up chemical reactions by lowering activation energy Activation energy = The energy required to start a chemical reaction Macromolecules = Large molecules made of many cells and bonds
Test your knowledge of the scientific method with this final exam review quiz. Review the key concepts of controlled experiments, independent and dependent variables, and the evidence-based approach used by scientists to remove bias.
