The main purpose of respiration is
to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs
. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
What is the importance of respiration in plants?
Respiration is
essential for growth and maintenance of all plant tissues
, and plays an important role in the carbon balance of individual cells, whole-plants and ecosystems, as well as in the global carbon cycle.
What is importance of respiration in living things?
Respiration is the process of releasing energy from food and this takes place inside the cells of the body. Respiration is essential for life
because it provides energy for carrying out all the life processes
which are necessary to keep the organisms alive.
What are the importance of respiration in plants and animals?
Respiration is the
process of releasing energy from food
and this takes place inside the cells of the body. Respiration is essential for life because it provides energy for carrying out all the life processes which are necessary to keep the organisms alive.
What is difference between breathing and respiration?
Breathing and respiration are two completely different
but interrelated body processes which assist body organs to function properly
. Breathing is the physical process of exchanging gases whilst respiration is a chemical process which takes place at a cellular level and produces energy.
What do we need for respiration?
Glucose and
oxygen
react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work.
What is the importance of respiration in plants and human?
The main purpose of respiration is
to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs
. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
What are three importance of respiratory system?
These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it
brings oxygen into our bodies
, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.
What is the role of respiration in oxygen cycle?
The role of respiration in oxygen cycle is
to release carbon dioxide which is then taken up by the plants to carry out photosynthesis
, that release oxygen which is used up by human beings in respiration to produce carbon dioxide for plants again and this cycle goes on.
What is the respiration process?
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 types of respiration?
Three types of respiration include
internal, external, and cellular 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.
What is the importance of respiration in biology and our daily lives?
It is
the energy releasing and supplying process in all living organisms
. It converts food energy into metabolically usable forms of chemical energy. Respiration releases energy in a controlled and step-wise manner. Hence, most of the released energy is properly utilised for the cellular activities.
What is meant by breathing?
Breathing:
The process of respiration
, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction and then exhaled due to muscle relaxation.
What is a simple definition of respiration?
Respiration:
The act of inhaling and exhaling air in order to exchange oxygen for carbon dioxide
.
What is the most basic function of respiration?
The main function of the respiratory system is
the exchange of oxygen from the atmosphere for carbon dioxide produced by the cells of the body
.
What are the two types of respiration?
There are two types of cellular respiration (see Cellular Respiration concept):
aerobic and anaerobic
. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic).
