Food supplies an organism with many small, energy-rich molecules. These molecules are taken in by the organism's cells. Inside cells, the molecules from food are broken down to release energy that cells can use. This energy powers cell processes that allow the entire organism to grow and live. Select all the true statements.
Cells take in small, energy-rich molecules from food. These molecules include sugar molecules. Cells use the molecules in a long series of chemical reactions. These reactions are known together as cellular respiration. Cellular respiration breaks down energy-rich molecules to form different molecules. This process also releases energy. Which of the following statements are true about cellular respiration? Select all that apply.
Glucose, like other sugar molecules, often serves as an energy source for cells. Cells release energy by breaking down glucose through chemical reactions with oxygen gas. This process produces carbon dioxide gas and water. Which of the following substances are key reactants of this process? Select two.
glucose + oxygen --> carbon dioxide + water
Which of the following substances are key products of this process?
Select two.
All organisms need food for energy. But how does an organism's body actually get energy out of food? Food supplies an organism with many small, energy-rich molecules. These molecules are taken in by the organism's cells. Inside cells, the molecules from food are broken down to release energy that cells can use. This energy powers cell processes that allow the entire organism to grow and live. Select all the true statements.
