The Km of your favorite enzyme that operates by normal Michaelis-Menten kinetics is 10-6 M. You start off with a substrate conce
swat32

Answer: (a) 0 no free enzyme left

(b) 10^-9M

Explanation:

ANSWER:

Given that

Kcat = 10 sec-1

Km = 10^-6 M

[S] = 10^-3 M

[Enzyme] = 10^-9 M

The reaction follows the following path-

Enzyme (E) + Substrate (S) <=> ES complex -> E + Product (P)

According to the improved model of Michaelis-Menten kinetics, upon addition of substrate and the enzyme, instead of dynamic equilibrium, a steady state is reached. The time taken is very less, almost instantaneously (since Kcat is much higher than the concentrations we are dealing with (10 per second! Whereas we are dealing with concentrations as low as 10-9).

In this steady state, the Enzyme and substrate instead of existing individually, exist as an Enzyme-Substrate complex, or ES complex.

Physically, Km is a measure of how well substrate complexes with an enzyme, i.e. It's binding affinity.

You can imagine this as if 1 unit of the substrate can bind to "Km" units of Enzyme. For the give conditions, 1 M of the substrate requires 10^-6 M enzyme for complete binding. So, 10^-3 M of the substrate will require 10^-3 x 10^-6 = 10^-9 M of the enzyme, which is the exact amount of enzyme added to the reaction mixture.

So it is safe to assume that when the steady state is reached, all of the enzyme is bound to the available substrate producing the ES complex with the concentration equal to the limiting reactant, i.e. the enzyme = 10^-9 M

Hence, there will be no free enzyme left after the short duration of the reaction. And the concentration of the ES complex will be 10^-9 M

Describe how the structures of proteins differ from the structures of carbohydrates (150 words)
Veronika [31]

well both are considered macromolecules. proteins are like big lego construction. each single piece gets pieced together to make a larger thing. each single piece is a monomer, and the larger construction is the polymer. the monomers are called amino acids and they get pieced together to form the polymer which is called a protein. the linkage that they use is an amide bond, and in biology it is usually called a peptide bond. carbohydrates can be singular monomers or polymer units. they are made of completely different compounds usually aldehydes or ketones. and they link together through different chemical linkages (acetal or ketal linkages for polymers, hemiacetal or hemiketal linkages for monomers). both can be large, 3D strucutres proteins are only functional as a large, 3D structure, while carbohydrates can be singular. (you might wanna word it differently for safety reason)

What is Pricipitation
irinina [24]

Answer:

Precipitation is rain, snow, sleet, or hail — any kind of weather condition where something's falling from the sky. Precipitation has to do with things falling down, and not just from the sky. It's also what happens in chemical reactions when a solid settles to the bottom of a solution.

Which consist of sperm cells and egg cells?gametes tetrads diploids chromosomes
REY [17]
<span>The sex cells, more scientifically known as the ova and spermatozoa, are composed of 23 of the usually 46 human chromosomes. They have half the usual number because they of course combine to form a new, genetically distinct, cell, termed the zygote. The correct term for this type of cell, one with half of the complete genome, is GAMETE. Therefore the answer is option (a).</span>
