Glycolysis is the first step of cellular respiration - the process comprised of series of reactions in which energy is extracted from glucose molecules. The process of glycolysis is almost same in all living organisms.
If we quickly overview the process of glycolysis, we see that it is a process of earning ATPs as a return on ATP investment, why?
- 2 ATP molecules are invested during the first or preparatory phase pf glycolysis.
- 2 ATP molecules are formed for each glyceraldehyde 3-phosphate molecule. Therefore, total four ATP molecules are produced.
- Other than ATP, 1 NADH + H+ is also produced for each molecule of glyceraldehyde 3-phosphate.
Therefore,total amount of 2 NADH and 4ATP molecules are produced.
But since, there was an investment of two ATPs during the preparatory phase of glycolysis. Therefore, a total of 4-2=2 ATPs is formed/ So it is like an earning on an investment.
Hope it help!
Answer: Maintainance of constant internal environment is carried out in a process called Homeostasis.
Explanation:
Maintainance can of several types such as pH, temperature, and other substances such as Concentration of Ammonia in body. These all should maintain at constantly for stability in body. The maintenance of temperature is called thermo regulation.
All the above are correct statement of mRNA !!
It is transcribed from template stand ; moves out of nucleus ; take the gene info to ribosomes which is the site of protein synthesis !!
