Answer:
B) A series of chemical reactions where enzymes work one at a time to convert a reactant into intermediates and the intermediates into a final product.
Explanation:
In our cells there are multiple chemical reactions happening all the time to convert the elements we ingest (food, water, air) into the products the organism needs.
This processes can be very complex and offen involves various reactions (steps). Also, many of this reactions need to by catalized by enzymes in order to happen.
Gallium is the metal that will be solid at room temperature but will melt in the hands when picked up. Gallium is the metal that has the property of melting at a temperature which is just above the room temperature. It is a very rare property of a metal.This property of the metal makes it totally unusable for making anything.
This is a metal that can only be used for doing certain
tricks for making people laugh and happy.
Answer:
Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme
Explanation:
Enzyme are biological catalysts.
So they do alter the path of the reaction where the free energy change (or activation energy) is low then the non enzymatic pathway.
Thus the statement
Enzymes alter the free energy change (ΔG) of the reactions which they catalyze : True
It is known that for enzyme we function they need an optimum temperature and pH condition so the statement
Enzyme function is dependent on the pH and temperature of the reaction environment: true
This is also true that
Enzyme activity can be inhibited if the enzyme is bound by a noncompetitive inhibitor.
The false statement is : Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme
Answer:
Mass = 72.52 g
Explanation:
Given data:
Mass of hydrogen phosphate produced = ?
Mass of P₂O₅ react = 105.9 g
Solution:
Chemical equation:
P₂O₅ + 3H₂O → 2H₃PO₄
Number of moles of P₂O₅:
Number of moles = mass/molar mass
Molar mass of P₂O₅ 283.9 g/mol
Number of moles = 105.9 g/ 283.9 g/mol
Number of moles = 0.37 mol
Now we will compare the moles of P₂O₅ with H₃PO₄ from balance chemical equation.
P₂O₅ : H₃PO₄
1 : 2
0.37 : 2/1×0.37= 0.74 mol
Mass of H₃PO₄ :
Mass = number of moles × molar mass
Mass = 0.74 mol × 98 g/mol
Mass = 72.52 g
