Explanation:

• Question 1: Cellular respiration is a metabolic process. The general chemical reaction is \(C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O+\text{ATP}\). Reactants are glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)). Products are carbon dioxide (\(CO_2\)), water (\(H_2O\)) and ATP.

• Question 2: Mitochondria are the power - houses of the cell. In cellular respiration, carbon dioxide is a waste product released. So the substance represented by the arrows is carbon dioxide.
• Question 3: The raw materials for cellular respiration are glucose and oxygen. Among the options, oxygen is a raw material.
• Question 4: The diagram shows the reaction \( \text{Nutrient (sugar)}+\text{Oxygen}

ightarrow\text{Water}+\text{Carbon dioxide}+\text{Energy}\), which is the process of cellular respiration.

• Question 5: In cells, the energy released from cellular respiration is transferred to ATP (adenosine triphosphate) which acts as the energy currency of the cell.
• Question 6: Mitochondria are the organelles responsible for producing energy (ATP) through cellular respiration.
• Question 7: Mitochondria (if structure C is mitochondria) produce ATP most efficiently. ATP is synthesized in mitochondria through oxidative phosphorylation.
• Question 8: Glucose (\(C_6H_{12}O_6\)) is the energy - rich organic compound that is broken down in cellular respiration to synthesize ATP.
• Question 9: If structure A is a mitochondrion, its function is to produce ATP through cellular respiration.

Answer:

1. \(C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O+\text{ATP}\); Reactants: \(C_6H_{12}O_6\), \(O_2\); Products: \(CO_2\), \(H_2O\), ATP

1. (3) carbon dioxide
2. (3) oxygen
3. Cellular respiration
4. (2) ATP
5. (3) mitochondrion
6. (3) ATP is produced most efficiently by structure C (assuming C is mitochondrion)
7. Glucose (\(C_6H_{12}O_6\))
8. If A is mitochondrion: Mitochondrion; Function: Produce ATP through cellular respiration
