What is Respiration

The transfer of oxygen from the outside environment to cells within
tissues, as well as the removal of carbon dioxide in the opposite way, is
referred to as respiration. It is a biological reaction that takes place within
the cells of living organisms.

The process by which organisms exchange gases, especially oxygen and
carbon dioxide, with the environment. In air-breathing vertebrates,
respiration takes place in the lungs.

What is Aerobic Respiration?

Aerobic Respiration is the process of cellular respiration that takes place in the
presence of oxygen gas to produce energy from food. This type of respiration is
common in most of the plants and animals, birds, humans, and other mammals. In
this process, water and carbon dioxide are produced as end products.

Example of aerobic Respiration.

Examples for aerobic respiration are all multicellular organisms like;

Birds

Animals

insects

Humans

And more

Examples of respiration in living organisms.

Insects breathe through holes in their body called
spiracles. Tubes called trachea carry oxygen throughout
the body. Fishes and other animals that live in water use
organs called gills instead of lungs to take in oxygen from
the water. Some fishes and many amphibians exchange
gases through their skin as well.

Importance of Respiration of living organism.

Respiration is important because it produces energy that is necessary for the
functioning of the body. It provides oxygen to the cells and expels toxic carbon
dioxide. When oxygen reaches the cells, this oxygen breakdown glucose which is
present in digested food, and releases energy.

Importance of Aerobic respiration

Aerobic respiration is important because our cells use this process to
convert oxygen and food into the energy that we depend on for life. Gas
exchange may not seem like a thrilling concept, but the ability to
exchange gas is the reason why you and nearly every creature on this
planet are alive.

The exchanges of oxygen and carbon dioxide across the alveoli.

Blood passes through the capillaries, entering through your PULMONARY
ARTERY and leaving via your PULMONARY VEIN. While in the
capillaries, blood gives off carbon dioxide through the capillary wall into
the alveoli and takes up oxygen from air in the alveoli.

The structure and basic function of the human respiratory system

Your respiratory system is made up of your lungs, airways (trachea, bronchi and
bronchioles), diaphragm, voice box, throat, nose and mouth. Its main function is to
breathe in oxygen and breathe out carbon dioxide. It also helps protect you from
harmful particles and germs and allows you to smell and speak.

Difference of photosynthesis and respiration.

Both are processes within the cell which make chemical energy available for
life. Photosynthesis transforms light energy into chemical energy stored in
glucose, and cellular respiration releases the energy from glucose to build
ATP, which does the work of life.

Cellular respiration and photosynthesis are important parts of the carbon
cycle. The carbon cycle is the pathways through which carbon is recycled in
the biosphere. While cellular respiration releases carbon dioxide into the
environment.

Describe respiration in energy that released from food either in the
presence or absence of oxygen.

All living cells respire. This process releases the energy stored in glucose for life
processes.

Cellular respiration can occur both aerobically (using oxygen), or anaerobically
(without oxygen). During aerobic cellular respiration, glucose reacts with oxygen,
forming ATP that can be used by the cell. Carbon dioxide and water are created as
byproducts.

Aerobic respiration occurs in the presence of oxygen, whilst anaerobic respiration
occurs without it.Aerobic Respiration: It is the process of cellular respiration that
takes place in the presence of oxygen gas to produce energy from food

The types of criteria required for aerobic respiration.

Aerobic respiration requires oxygen (O2) in order to create ATP. Although
carbohydrates, fats and proteins are consumed as reactants, aerobic respiration is
the preferred method of pyruvate production in glycolysis, and requires pyruvate to
the mitochondria in order to be fully oxidized by the citric acid cycle.

Aerobic respiration equation.

Aerobic respiration: In the presence of oxygen, glucose is broken down to form
carbon dioxide, water and large amounts of energy.

Both

Glucose + oxygen → carbon dioxide + water + energy (38 ATP).

The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen ->
carbon dioxide + water).

Difference between respiration and breathing

Breathing and respiration are two completely different but interrelated
body processes that assist body organs to function properly.

Breathing is a mechanical process where the air volume changes in the
chest cavity. On the other hand, respiration is a biochemical process
where oxygen is introduced into the bloodstream and carbon dioxide is
expelled from the body.

Compare photosynthesis and respiration and explain how
they are linked.
Respiration is the reversal of the biochemical pathways of photosynthesis.
Photosynthesis stores energy in complex organic molecules, while respiration
releases it.

Photosynthesis makes the glucose that is used in cellular respiration to make
ATP. The glucose is then turned back into carbon dioxide, which is used in
photosynthesis. While water is broken down to form oxygen during
photosynthesis, in cellular respiration oxygen is combined with hydrogen to
form water.
