Question

releasing energy
energy is released during all stages of cellular respiration. a small amount of energy is released when the sugar molecules are broken down in the cytoplasm. a large amount of energy is released by the chemical reactions in the mitochondria. cells use this energy for life processes. the other products of cellular respiration—water and carbon dioxide—are released by the cell.

1. use the word bank to write the chemical equation for cellular respiration.

word bank

• 6h₂o • 6co₂
• 6o₂ • energy
• c₆h₁₂o₆

Explanation:

Step1: Recall cellular respiration equation

The chemical equation for cellular respiration is the breakdown of glucose (\(C_6H_{12}O_6\)) in the presence of oxygen (\(O_2\)) to produce carbon dioxide (\(CO_2\)), water (\(H_2O\)) and energy. The balanced equation is \(C_6H_{12}O_6 + 6O_2
ightarrow 6CO_2 + 6H_2O + \text{energy}\).

Step2: Match with word bank

From the word bank, the reactants are \(C_6H_{12}O_6\) (glucose) and \(6O_2\) (oxygen), and the products are \(6CO_2\) (carbon dioxide), \(6H_2O\) (water) and energy. So the equation should be filled as \(C_6H_{12}O_6 + 6O_2
ightarrow 6CO_2 + 6H_2O + \text{energy}\) (placing each compound in the respective boxes from left to right as per the equation structure: reactants on left of arrow, products on right).

Answer:

\(C_6H_{12}O_6\) + \(6O_2\) \(
ightarrow\) \(6CO_2\) + \(6H_2O\) + energy (filling the boxes in order: first box \(C_6H_{12}O_6\), second \(6O_2\), third \(6CO_2\), fourth \(6H_2O\), fifth energy)
