Answer:
Ratio = 9 : 2
Explanation:
We have been given two resistors, one with 2ohms rating and another with 4 ohms rating.
First they are connected in series. When resistors are connected into series, Equivalent resistance is given by:
Resistance (Equivalent) = R₁ + R₂ = 6 ohms
When these are connected in parallel, equivalent resistance becomes:
1 / Resistance (Equivalent) = 1/R₁ + 1/R₂ = 1/2 + 1/4
1 / Resistance (Equivalent) = 3/4
Resistance (Equivalent) = 4/3
Ratio = R(Series)/ R(Parallel)
Ratio = 6 : 4/3
Ratio = 18 : 4
Ratio = 9:2
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!
