Answer:
is usually structurally similar to the substrate.
Explanation:
Competitive inhibitors resemble normal substrate and binds to enzyme at the active site usually and prevents substrate from binding.
Active sites are main location for the substrate-enzyme binding. These sites involve weak as well as reversible bonds between the substrate and the enzyme. These inhibitors bind to the active sites and form weak and reversible bonds. Competitive inhibitors can be dissociated from active site by increasing concentration of the substrates. Substrates has to compete for active site and displace the bound competitive inhibitors.
<u>Hence, correct option is - is usually structurally similar to the substrate.</u>
Answer:
65.4 is the mass for 1.9×10²⁴ atomsof Pb
Explanation:
1mol of atoms of Pb has → NA (6.02×10²³ atoms) and weighs → 207.2 g
Therefore 1.9×10²⁴ atomsof Pb may weigh (1.9×10²⁴ . 207.2) / NA = 65.4 g
Molarity of methanol is 0.223 M.
<u>Explanation:</u>
We need to find the molarity of methanol by using the given mass and volume in litres by finding its moles using the given mass and molar mass and then using the moles and volume, we can find the molarity of the solution.
Molarity = 
Moles = 
= 
= 0.78 moles
Now, we can find the molarity as,
= 0.223 M
So the concentration of methanol solution is 0.223 M.
