Question

Define the process of respiration in living organisms

Answer 1

Answer:Respiration is a metabolic process common to all living things

When you breathe, you are taking in oxygen with each inhale and releasing carbon dioxide with each exhale. This gas exchange is important for respiration, but while breathing is a physical process, respiration can be thought of as more of a chemical process. All organisms, from a single bacterial cell to a coral reef colony to a blue whale, undergo respiration.

Food molecules absorbed after digestion are taken in, broken down, and the energy freed in the process is used to power the organism's movements and physiological functioning. Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells).

Respiration is the process which involves the chemical break down of glucose to release ATP (energy) for the body. C02 is a biproduct which is expelled through the lungs.

There are two types of respiration: -

• Aerobic respiration - This is the breakdown of Glucose in the abundance of oxygen this is the more efficent of the two processes and creates the most amount of energy. 52 molecules of ATP.

CHEMICAL FORMULA for Aerobic respiration : -

• $\bf \: C_6H_{12}O_6 + 6O_2 \: \rightarrow \: 6CO_2 + 6H_2O + Energy$

• Anaerobic respiration - This is the breakdown of Glucose in the absence of oxygen. This is not an efficient process, only 2 molecues of ATP are produced and a biproduct is lactic acid. which is what causes aches and cramps in muscles after excercise.

CHEMICAL FORMULA for Anearobic respiration : -

• $\bf \ C_6H_{12}O_6 \ \rightarrow \ 2C_3H_6O_3 + 2 ATP$
