Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose and oxygen.

Front

What are the products of cellular respiration?

Back

The products of cellular respiration are carbon dioxide, water, and energy (ATP).

Front

How are photosynthesis and cellular respiration related?

Back

The reactants of cellular respiration (glucose and oxygen) are obtained from the products of photosynthesis (glucose and oxygen).

Front

What is a control group in an experiment?

Back

A control group is a standard of comparison in an experiment that is not exposed to the experimental treatment.

Front

What is a dependent variable?
