How is the ATP produced in glycolysis like earning a return on an investment ?
telo118 [61]

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!

If biological species are defined in terms of reproductive compatibility, the formation of a new species hinges on ________.
soldier1979 [14.2K]

Answer:

  • <u> Option-(B): </u> If biological species are defined in terms of reproductive compatibility, the formation of a new species hinges on <u>reproductive isolation.</u>                            

Explanation:

  • There is diversity among being and we see that millions of species roam the face of land, all this happens in the tenure of centuries. While the process of evolution or creation of new species happens when a certain specie is kept inside such an environment or a very unique environment that the species is tempted to cross with another form of organism belonging to a different specie, so, this process initiates the creation of new species or organisms having a very different set of characteristics as compared to there ancestors.

Is Natural selection a universal process?
bezimeni [28]
The probability of life evolving into a complex form is one of the factors in the Drake equation. Drake himself estimated that probability as 1.0, for what that's worth.

<span>He had that confidence precisely because descent-with-variation seems pretty certain to be a universe process because it's so straightforward. If you have something that reproduces imperfectly, eventually more complex versions will be the result. Even the "natural selection" part is optional if you were just imagining searching through the vast space of genetic possibilities, but finite resources make selection inevitable.</span>
