What elements make up respiration?
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
Which element is an important part of respiration?
Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive.
What are 6 parts of respiration?
These are the parts:
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
What are the 3 processes of respiration?
Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.
What are the functions of the respiratory system?
In addition to air distribution and gas exchange, the respiratory system filters, warms, and humidifies the air you breathe. Organs in the respiratory system also play a role in speech and the sense of smell. The respiratory system also helps the body maintain homeostasis, or balance among the many elements of the body’s internal environment.
What are the three stages of cellular respiration?
The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP.
Which is the correct equation for aerobic respiration?
The overall equation of aerobic respiration can be summed up as: sugar + oxygen → carbon dioxide + water + energy You may recognize that this is the opposite reaction to photosynthesis which uses the sun’s energy and water to convert carbon dioxide into sugar and oxygen.
What happens to the energy released during respiration?
The series of reactions gradually releases the energy of molecules such as glucose. The released energy is transferred to molecules such as ATP and used to power activity within cells. Cellular respiration can be both aerobic or anaerobic.
