Answer:
Lysine 63.
Explanation:
The coenzyme may be defined as the non protein part of an enzyme that plays an important role in the enzyme functioning. Any cation or small molecule like amino acids can acts as coenzyme.
Lipoamide is important coenzyme that plays an important role in the metabolic pathways by undergoes the decarboxylation reactions. The reduced lipoamide known as dihydrolipoamide is used for the covalent attachment at Lysine 63 residues.
Thus, the correct answer is option (D).
Answer:
2.52 g H₂
Explanation:
To find the mass of hydrogen gas, you need to (1) convert moles H₂O to moles H₂ (via mole-to-mole ratio from reaction coefficient) and then (2) convert moles H₂ to grams H₂ (via molar mass from periodic table values). When multiplying the given value by the mole-to-mole ratio, you need to use the coefficients of the balanced equation. An reaction is balanced once there is an equal amount of each element on both sides.
<u>(Step 1)</u>
The unbalanced equation:
Ca(s) + H₂O(l) ----> Ca(OH)₂(aq) + H₂(g)
<u>Reactants</u>: 1 calcium, 2 hydrogen, 1 oxygen
<u>Products</u>: 1 calcium, 4 hydrogen, 2 oxygen
The balanced equation:
1 Ca(s) + 2 H₂O(l) ----> 1 Ca(OH)₂(aq) + 1 H₂(g)
<u>Reactants</u>: 1 calcium, 4 hydrogen, 2 oxygen
<u>Products</u>: 1 calcium, 4 hydrogen, 2 oxygen
<u>(Step 2)</u>
Molar Mass (H₂): 2(1.008 g/mol)
Molar Mass (H₂): 2.016 g/mol
<u>(Step 3)</u>
2.50 moles H₂O 1 mole H₂ 2.016 g
--------------------------- x ------------------------- x ---------------------- = 2.52 g H₂
2 moles H₂O 1 mole
