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:
The Viking tubing is meant to be the cell membrane. Glucose manages to move out of the bag and into the surrounding water but starch does not. Not all substances can pass through the cell membrane; some molecules, like starch are too large. The cell membrane is called selectively permeable because of this.
