Front

What is the functional group hydroxyl (-OH)?

Back

The hydroxyl group is polar and forms bonds with water.

Front

What is the final electron acceptor of aerobic respiration?

Back

Oxygen.

Front

What is the energy needed to start a reaction called?

Back

Activation energy.

Front

What is the name of the functional group that contains a carbonyl group?

Back

Carboxyl.

Front

What distinguishes a scientific theory from a hypothesis?

Back

A theory is a well-substantiated explanation, while a hypothesis is a testable prediction usually narrower in scope.

Front

What is the structure of a carboxyl group?

Back

A carboxyl group consists of a carbon atom double-bonded to an oxygen atom and also bonded to a hydroxyl group (-COOH).

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to lower the activation energy of reactions, speeding up the process.

Front

Define polar molecules.

Back

Polar molecules have a distribution of electrical charge that leads to partial positive and negative charges, allowing them to interact with water.

Front

What is the difference between a saturated and unsaturated fatty acid?

Back

Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids contain one or more double bonds.

Front

What is the function of ATP in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells.
