Answer:

It is an amorphous solid and hence also called pseudo solid. So it flows very slowly over thousands of years. It is not visible to the n*ked eye.

What would happen if a cell membrane let too much water into a cell?

Sloan [31]

Answer:

<u>Animal Cell</u>

When water moves into an animal cell (e.g. a red blood cell), the cell membrane stretches and the cell gets bigger. If this continues, the cell membrane will burst – this is called lysis.

<u>Plant Cell</u>

When too much water moves out of a plant cell the cell contents shrink. This pulls the cell membrane away from the cell wall. A plasmolyzed cell is unlikely to survive.

Furkat [3]

Answer:

The value of the Michaelis–Menten constant is 0.0111 mM.

Explanation:

Michaelis–Menten 's equation:

$v_o=V_{max}\times \frac{[S]}{(K_m+[S])}=k_{cat}[E_o]\times \frac{[S]}{(K_m+[S])}$

$V_{max}=k_{cat}[E_o]$

Where:

$v_o$ = rate of formation of products

[S] = Concatenation of substrate

$[K_m]$ = Michaelis constant

$V_{max}$ = Maximum rate achieved

$k_{cat}$ = Catalytic rate of the system

$[E_o]$ = Initial concentration of enzyme

On substituting all the given values

We have :

$\frac{v_o}{V_{max}}=0.90$

[S] = 0.10 mM

$\frac{v_o}{V_{max}}=\frac{[S]}{(K_m+[S])}$

$0.90=\frac{0.10 mM}{K_m+0.10 M}$

$K_m=0.0111 mM$

The value of the Michaelis–Menten constant is 0.0111 mM.

One thing incorrect is that when dealing with a compound, such as H2SO4, that has 7 atoms in the chemical formula, the polyatomic ion SO4 doesn’t dissociate into one Sulfur and four Oxygens. SO4 stays and a PAI.
