Which of the following best describes the relationship between breathing and respiration?
- Breathing and respiration are the same process and can be used interchangeably.
- Breathing is the process of gas exchange, while respiration is the release of energy from glucose.
- Respiration is the mechanical process of moving air, while breathing is the chemical process of energy release.
- Breathing is the mechanical process of moving air into and out of the lungs, while respiration is the chemical process of energy release. (correct)
During inhalation, which of the following occurs?
During inhalation, which of the following occurs?
- The diaphragm contracts, and the intercostal muscles relax.
- Both the diaphragm and intercostal muscles relax.
- Both the diaphragm and intercostal muscles contract. (correct)
- The diaphragm relaxes, and the intercostal muscles contract.
Which equation represents aerobic respiration?
Which equation represents aerobic respiration?
- $C_6H_{12}O_6 + 6O_2 → 6CO_2 + 6H_2O + Energy$ (correct)
- $C_6H_{12}O_6 → 2C_2H_5OH + 2CO_2$

Human Respiration and Energy Release
- Organisms require energy for various reasons.
- An experiment can demonstrate the release of energy from food.
- Results of experiments can be more reliable by controlling variables.
- Food contains energy.
- Respiration is a chemical reaction that releases energy from glucose.
- ATP is a chemical that stores energy.
- ATP is produced during respiration.
- Cells require two substances to release energy in aerobic respiration.
- Aerobic respiration produces waste products.
- Aerobic respiration can be represented by an equation.
- Cells can obtain energy without oxygen.
- Fermentation in animal cells can be represented by an equation.
- Fermentation in plant and yeast cells can be represented by an equation.
- Aerobic respiration and fermentation have three key differences.
- Breathing and respiration have four key differences.
- An experiment can demonstrate the difference in carbon dioxide levels between inhaled and exhaled air.
- Inhaled and exhaled air differ in composition in three ways.
- Inhalation (inspiration) and exhalation (expiration) describe the process of air entering and exiting the lungs.
- Two muscles are involved in inhalation and exhalation.
- Gas exchange happens within the lungs.
- Alveoli have four key features that make them efficient at gas exchange.
- A peak flow meter can be used to measure lung function.
- A peak flow meter measures a person's peak flow.
- Knowing someone's peak flow reading provides useful information about their respiratory health.
- Cilia plays a role in keeping the lungs clean.
- Mucus plays a role in keeping the lungs clean.
- Cilia and mucus work together to keep the lungs clean.
- Smoking or vaping can affect the cleaning system of the lungs.
- Lifestyle choices or diseases can affect the human respiratory system.
Key Vocabulary
- Breathing involves the intercostal muscles and diaphragm working together to inflate and deflate the lungs.

- Fermentation is a process where sugar is broken down by bacteria or yeast.
- Alveoli are tiny air sacs in the lungs where oxygen goes into the blood and carbon dioxide comes out.
- Inhalation is the process of breathing in air.
