This is a reaction going on in your muscle cells right this very minute:The enzyme triose phosphate isomerase catalyzes this rea

Arisa [49]

Explanation:

The given reaction is as follows.

$E + S \rightleftharpoons ES \xrightarrow[]{k_{2}} E + P$

Here, [E] = triose phosphate isomerase = 0.1 $nm = 0.1 \times 10^{-9}m$

[S] = Dihydroxy acetone phosphate = 5 $\mu m = 5 \times 10^{-6}m$

[P] = Glyceraldehyde-3-phosphate = 2 $\mu m = 2 \times 10^{-6}m$

Therefore, velocity of the reaction will be as follows.

v = $\frac{d[P]}{dt}$ = $\frac{K_{2}[E][S]}{K_{M} + [S]}$

where, $K_{M}$ = Michaelic menten constant = $\frac{K_{1} + K_{2}}{K_{1}}$

v = $\frac{900 \times 0.1 \times 10^{-9}m \times 5 \times 10^{-6}m}{10^{-5} + 5 \times 10^{-6}}$

= $30 \times 10^{-9} m$

or, = 30 nm/s

Hence, we can conclude that the actual velocity of the forward reaction under physiologic conditions if KM = 10 μM is 30 nm/s.

What is the volume of 25 g iodine, density = 4.93 g/cm^3??

aniked [119]

Mass=25g
Density=4.93g/cm^3

$\\ \rm\rightarrowtail Volume=\dfrac{Mass}{Density}$

$\\ \rm\rightarrowtail Volume=\dfrac{25}{4.93}$

$\\ \rm\rightarrowtail Volume=5.1cm^3$

Why is it possible to bend metals but not ionic crystals

dezoksy [38]

It pushes the positive ions together, the positive ions repel each other, causing the crystal to shatter
