Let's go through the 2.2.5 Respiration Worksheet and fill in the blanks with correct answers, along with explanations for each section.
---
- The food involved in respiration is usually _glucose_.
*Explanation:* Glucose is the primary fuel molecule used in cellular respiration. It is a simple sugar that cells break down to release energy.
- Internal respiration is controlled by _mitochondria_ which allow energy to be released in _small, manageable amounts_.
*Explanation:* Mitochondria are the organelles where aerobic respiration occurs. They regulate the process so that energy is released gradually and efficiently, preventing damage from sudden energy bursts.
- The energy is trapped in molecules called _ATP (Adenosine Triphosphate)_.
*Explanation:* ATP is the energy currency of the cell. The energy from glucose breakdown is stored in ATP bonds and used for cellular work.
---
- Aerobic Respiration – the release of energy from food in the _presence_ of oxygen
*Explanation:* Aerobic means "with oxygen." This process requires oxygen to fully break down glucose and produce maximum ATP.
- Anaerobic Respiration – the release of energy from food _without_ the presence of oxygen
*Explanation:* Anaerobic means "without oxygen." This process occurs when oxygen is limited, producing less ATP than aerobic respiration.
---
- Most living things get energy from aerobic respiration and are called _aerobes_.
*Explanation:* Organisms that rely on oxygen for respiration are known as aerobes.
- The energy stored in _chemical bonds_ in glucose is released and used to make _ATP_.
*Explanation:* Glucose contains high-energy chemical bonds. When these bonds are broken during respiration, energy is captured to form ATP.
- When ATP breaks down it _releases energy_ for all the reactions in a cell such as movement of muscles, growth of new cells, etc.
*Explanation:* ATP stores energy in its phosphate bonds. When ATP is hydrolyzed (broken down into ADP + Pi), energy is released and used for cellular processes.

There are two versions of the equation:
1. Word Equation:
_Glucose_ + _Oxygen_ → _Carbon dioxide_ + _Water_ + _Energy_
2. Chemical Equation:
_C₆H₁₂O₆_ + _6O₂_ → _6CO₂_ + _6H₂O_ + _Energy_
*Explanation:* This is the balanced chemical equation showing how one molecule of glucose reacts with six molecules of oxygen to produce six molecules of carbon dioxide, six molecules of water, and energy (stored in ATP).
---
- Aerobic respiration is relatively _efficient_, 40% of the energy in glucose is used to make ATP
*Explanation:* Although only about 40% of the energy from glucose is converted into ATP, this is still highly efficient compared to anaerobic respiration.
- Any energy not used to produce ATP is _lost as heat_.
*Explanation:* The remaining 60% of energy is released as heat, which helps maintain body temperature in warm-blooded animals.

Respiration is the controlled release of energy from food
- The food involved in respiration is usually glucose.
- Internal respiration is controlled by mitochondria which allow energy to be released in small, manageable amounts.
- The energy is trapped in molecules called ATP.
Types of Respiration
- Aerobic Respiration – the release of energy from food in the presence of oxygen.
- Anaerobic Respiration – the release of energy from food without the presence of oxygen.
Aerobic Respiration
- Most living things get energy from aerobic respiration and are called aerobes.
- The energy stored in chemical bonds in glucose is released and used to make ATP.
- When ATP breaks down it releases energy for all the reactions in a cell such as movement of muscles, growth of new cells, etc.
Equation for Aerobic Respiration
- Glucose + Oxygen → Carbon dioxide + Water + Energy
- C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy
Final Statements
- Aerobic respiration is relatively efficient, 40% of the energy in glucose is used to make ATP.
- Any energy not used to produce ATP is lost as heat.
