BREATHING AND RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Respiration is ____
A
The movement of the diaphragm
B
Breaking down starch to sugar
C
Releasing energy from glucose
D
Breathing
Explanation: 

Detailed explanation-1: -Respiration is the process through which living organisms take in oxygen and give out carbon dioxide to release energy. During respiration, there is a release of carbon-dioxide and water when glucose is broken down in the presence of oxygen. During this reaction, the energy is released.

Detailed explanation-2: -During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).

Detailed explanation-3: -Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use. Cellular respiration consists of three metabolic processes: glycolysis, the Krebs cycle, and oxidative phosphorylation.

Detailed explanation-4: -Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. The hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and phosphoric acid (Pi) releases energy (it is an exergonic reaction).

Detailed explanation-5: -Aerobic respiration It releases energy stored in glucose and without it, these cells would die. Aerobic respiration slowly releases lots of energy stored in glucose . It mostly occurs in tiny parts of your cells called mitochondria which are found in the cytoplasm .
