Answer:
A subunit of Rubisco takes approximately 0.33 s to perform one reaction
Explanation:
The kcat it's a kinetic first order constant that related the properties of the enzyme substrate complexes in a mechanisms and represents the overall first order process of the transformation of the substrate-enzyme complex into product.
Also kcat can be seen as the turnover number of an enzyme, representing the maximum number of substrate molecules that the enzyme can transform into product per time unit and per active site.
If the kcat is 3 s^-1, it means Rubisco can catalyse the transformation of 3 substrate molecules per second.
So, the time that takes a single reaction, should be the inverse of kcat.
To see it more clearly, the time needed for a single reaction is the time observed divided by the number of reactions done during that time.
In other words:
3 reactions ----------- 1 s
1 reaction -------------- x
- x=1 reaction/3 reactions.s^-1 = 1/kcat = 1/3 s ~ 0.33 s
So the time that takes one Rubisco subunit to do one reaction is approximately 0.33 s
Answer:
A molecule with 32 percent or more amount of Cytosine.
Explanation:
DNA is the genetic material of all the living organism but in few viruses, RNA can also acts as the genetic material. DNA contain nitrogenous bases ( adenine, guanine, thymine and cytosine), deoxyribose pentose sugar and the phosphate bond.
The triple bond is more stable than the double bond. Since, cytosine and guanine shows triple hydrogen bonding and shows more stability. The DNA molecule that contains more residues of guanine and cytosine is stable than the molecule containing adenine and thymine residues.
Thus, the answer is molecule with 32 percent or more amount of Cytosine.
Answer:
false
Explanation:
Mars has no rings. the only planets that do are Jupiter, Saturn, Neptune, and Uranus
Answer:
here is the answer
Explanation:
Scarlet king snakes cannot camouflage and so instead they mimic a dangerous neighbor. Scarlet king snakes have evolved over the years to look like coral snakes so that they could scare away other predators that may be dangerous and would want to hurt them
this is the reason
----- now the simplified answer
the scarlet snake has a very random ( rare ) genetic variation , it mimcs or
( behaves a like or looks like coral snake ) , it turns out that this trait helps the snake high chance of survival, snake with this kind of trait are often likely to reproduce and pass their traits to their children
now most of the scarlet snakes have this trait
trait ; a distinguishing quality or characteristic, typically one belonging to a person.
thank you
Has varied greatly over time
