What makes arteries unique ?
ehidna [41]

Arteries are blood carrying vessels which have thick, elastic,  muscular walls, have no valves and in which blood flows under high pressure. The make up of arteries is unique to their function of transporting blood under high pressure. 

All arteries carry oxygenated blood from the  heart to all other parts of the body, with the exception of the pulmonary artery which carries de-oxygenated blood from the heart to the lungs. It is the only artery that transports blood which has not been oxygenated.

The kcat for Rubisco is 3 sec-1 How long does it takeone<br> subunit of Rubisco to do one reaction.
bekas [8.4K]

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

What is the difference between asexual and sexual reproduction? This is a Science question. PLZ HELP!!!!!!
Olegator [25]

Asexual reproduction only requires one organism. It is normally faster and that’s how organisms make more in a short amount of time. Sexual reproduction uses 2 organisms and it gives the baby more diversity so it can adapt to the environment.
