Nature of Science
What is the process scientists use to test hypotheses?
What is the scientific method?
What type of macromolecule are enzymes?
What are proteins?
What are the four main types of macromolecules?
Carbohydrates, lipids, proteins, and nucleic acids.
What type of bond forms between water molecules?
What is a hydrogen bond?
What is the main molecule our bodies use for quick energy?
What are carbohydrates?
What is the variable that is measured or observed in an experiment?
What is the dependent variable?
What do enzymes do in chemical reactions?
They speed up reactions by lowering activation energy.
Which macromolecule stores genetic information?
What are nucleic acids?
Why is water called the “universal solvent”?
Because it can dissolve many substances.
Why is water so important for cells?
It helps transport substances and maintain temperature.
What is a control group used for?
To compare results and see the effect of the independent variable.
What happens to an enzyme when it is heated too much?
It denatures or loses its shape.
What is the main function of carbohydrates?
To provide quick energy.
What property allows water to stick to itself?
What is cohesion?
What happens to an enzyme after it helps a chemical reaction?
It stays the same and can be reused.
Why is peer review important in science?
It ensures accuracy and helps verify results.
What is the specific area on the enzyme where the substrate binds?
What is the active site?
Which macromolecule makes up cell membranes?
What are lipids?
What property allows water to stick to other surfaces?
What is adhesion?
How are proteins and enzymes related?
Enzymes are special types of proteins.
What is the difference between a scientific law and a theory?
A law describes what happens; a theory explains why it happens.
What is it called when an enzyme only works with one type of substrate?
What is enzyme specificity?
What element is found in all organic molecules?
What is carbon?
What happens to water when it freezes that makes ice float?
It becomes less dense.
How do macromolecules work together to keep organisms alive?
They provide energy, build cells, store information, and regulate reactions.
