    Dude we have good search engines these days, just shoot your question and you will have plenty of answers..

    Answer for respiration:

    In the most simple terms, "respiration" simply means "breathing". But more formally, the term depends on what type of respiration you are referring to. Essentially, "respiration" refers to gaseous exchange of unwanted carbon dioxide and much-needed oxygen for the body's use. In direct terms, oxygen is essential for life.

    There are two types of 'respiration': pulmonary (visible breathing) and cellular (which is not visible). Regular, visible (pulmonary) respiration is simply another term for breathing - or the inhalation-exhalation process. As unwanted air containing carbon dioxide is expelled from the body during exhalation, the chest 'falls' and a vaccuum is created inside the lungs. As new air containing needed oxygen is then sucked into the body to fill the vaccuum, the chest "rises". We call this the inhalation-exhalation process.

    In this process, the unwanted gas expelled is mainly carbon dioxide. This is then replaced during the inhalation breathing phase by the oxygen content within the air inhaled.

    The other respiration is called "cellular respiration". It occurs in the very local level of the cell itself, where a gaseous exchange takes place as unwanted carbon-dioxide is expelled through the cell walls and oxygen is diffused into the cell for energy purposes within the cell itself.

    There are different types of respiration. But the main two are cellular respiration and respiration as per physiology.

    Cellular respiration, also known as 'oxidative metabolism', is one of the key ways a cell gains useful energy. It is the set of the metabolic reactions and processes that take place in organisms' cells' mitochondria to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions that involve the oxidation of one molecule and the reduction of another.Nutrients commonly used by animal and plant cells in respiration include glucose, amino acids and fatty acids, and a common oxidizing agent (electron acceptor) is molecular oxygen (O2).

    In physiology, respiration (often mistaken with breathing) is defined as the transport of oxygen from the outside air to the cells within tissues, and the transport of carbon dioxide in the opposite direction. This is in contrast to the biochemical definition of respiration, which refers to cellular respiration: the metabolic process by which an organism obtains energy by reacting oxygen with glucose to give water, carbon dioxide and ATP (energy).

    Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the animal, while physiologic respiration concerns the bulk flow and transport of metabolites between the organism and the external environment.

    Hope it helps !

    if youre talking about cellular respiration, its the process of creating energy from glucose (sugar). Oxygen is used and Carbon Dioxide is the byproduct.

    Basic: It is the process you're body does to get energy. It uses glucose and oxygen and turns it into energy (ATP), carbon dioxide and water.

    There are two types of respiration, aerobic and anaerobic, the one mentioned above is aerobic.

    respiration is when oxygen is used with sugar to create energy (plus water and carbon dioxide)

    the formula is 6O2 +C6H12O6 --> 6CO2 + 6H2O

    oxygen glucose carbon dioxide water

    Breathing. Simple Enough?

    The mode of which an organism takes in a gas, such as oxygen, and exhales a gas, such as carbon dioxide.
