How many moles would there be in 100 g of glucose? In 500 g of glucose? SHOW WORK
vivado [14]

Answer:

a) 0.56moles

b) 2.78moles

Explanation:

The number of moles can be calculated by using the formula;

Mole (n) = Mass (M) ÷ Molar mass (MM)

For a glucose molecule, with chemical formula: C6H12O6

Where atomic mass of C= 12, H=1, O= 16

Molar mass of C6H12O6= 12(6) + 1(12) + 16(6)

= 72 + 12 + 96

= 180g/mol

a) In 100g of glucose;

Mole = 100/180

Mole = 0.56moles

b) In 500g of glucose

Mole = 500/180

Mole = 2.78moles

How does a noncompetitive inhibitor decrease the rate of an enzyme reaction?
Wittaler [7]

Answer :B. By changing the shape of the enzyme's active site.

check the attachment

Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the  active site.

On binding, it disrupts the  normal hydrogen bond and hydrophobic   interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and   ACTIVE SITE of the  enzyme (changed it shape).

Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit  for binding with the substrate, therefore  the efficiency  is reduced. No substrate-enzyme complex, and hence no substrate-product  complex for the release of  products, this brings down the turnover rate and eventually

<u>the rate of reaction of the enzyme</u>

Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
