What events occur during respiration quizlet?
Terms in this set (5)
- pulmonary ventilation. O2 into lungs from inspired air; CO2 out of lungs from expired air.
- external respiration. gas exchange between alveoli and the capillaries.
- respiratory gas transport. gasses are transported in blood (via vessels) to tissues.
- internal respiration.
- cellular respiration.
What events occur with respiration?
Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells. Every 3 to 5 seconds, nerve impulses stimulate the breathing process, or ventilation, which moves air through a series of passages into and out of the lungs.
What are the 4 process of respiration?
There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation. During glycolysis, glucose molecules (six-carbon molecules) are split into two pyruvates (three-carbon molecules) during a sequence of enzyme-controlled reactions. This occurs in both aerobic and anaerobic respiration.
What is the 4 phases of respiration?
The respiratory cycle is divided into 4 phases: inspiration (light green), end-inspiration (dark green), expiration (light red) and end-expiration (dark red).
What are the four steps of respiration?
Inhaling and exhaling may seem like simple actions, but they are just part of the complex process of respiration, which includes these four steps:
- Ventilation.
- Pulmonary gas exchange.
- Gas transport.
- Peripheral gas exchange.
What are the 4 main stages of cellular respiration?
The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
What are four functions of the respiratory system?
What does the respiratory system do?
- Allows you to talk and to smell.
- Warms air to match your body temperature and moisturizes it to the humidity level your body needs.
- Delivers oxygen to the cells in your body.
- Removes waste gases, including carbon dioxide, from the body when you exhale.
What are the four types of respiration?
Key Takeaways: Types of Respiration External respiration is the breathing process. It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells. Cellular respiration involves the conversion of food to energy.

What are the 4 stages of cellular respiration?
4 stages of cellular respiration are metabolic pathways that contribute to the production of ATP molecules in cells. The breakdown of glucose include such cellular respiration steps as glycolysis, the transition reaction, the Krebs cycle and oxidative phosphorylation. 4 main steps of cellular respiration – Biology Toggle Navigation Biology
What type of gas exchange occurs during cellular respiration?
internal respiration gas exchange between capillaries and tissue cells (individual cells) cellular respiration cell uses O2 to convert fuel to ATP Recommended textbook explanations
How many ATP are produced during cellular respiration?
Metabolic pathways that contribute to the production of ATP molecules in cells are collectively referred to as cellular respiration. When a molecule of glucose undergoes aerobic cellular respiration, 36 molecules of ATP are produced. Glucose is an energy-rich molecule.
