Lipoamide is a covalently attached coenzyme that plays a key role in several decarboxylase reactions, including glycine decarbox

ylase, and is attached to a lysine residue in the enzyme.
Review the molecule again. Manipulate it in order to identify the specific lysine residue that serves as the attachment site for lipoamide in the enzyme glycine decarboxylase. You may want to view the hint if you need help.

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).

How many atoms of the element with atomic number 11 are in the reactants of the given formula?
liq [111]

The number of Na atoms in the reactants = 2

<h3>Further explanation</h3>

Every chemical reaction involves compounds that can act as reactants or products

The reactants will react to produce products

The reactants are usually written on the left side of the reaction, while the products on the right side of the reaction

Reaction

2 NaCl + H₂SO₄ → 2 HCl + Na₂SO₄

The element with atomic number 11  = Na(Natrium)

The number of atoms of the element that reacts or is produced can be seen from the reaction coefficient and the number of atoms in the compound

Na in NaCl = 1 atom

From equation, cofficient for NaCl = 2, so number of atoms of Na=2 x 1 = 2

The ΔHvap of a certain compound is 49.09 kJ·mol–1 and its ΔSvap is 53.69 J·mol–1·K–1. What is the boiling point of this compound
rusak2 [61]
Hey there !

<span>Convert Joule to KJ :
</span>
1 j ---------------- 0.001 kj
53.69 j ----------- Kj

Kj = 53.69 * 0.001

=>  0.05369 Kj

T = ΔH / <span>ΔS

T = 49.09 / 0.05369

T = 914.32ºC</span>

In sediments and waterlogged soil, dissolved O2 concentrations are so low that the microorganisms living there must rely on othe
kakasveta [241]

Answer:

1) SO₄ ²⁻ : (+6)

  H₂S : (-2)

Explanation:

a) <u>Sulfate reducers</u> are widespread in muds and other sediments, water-logged soils, etc., environments that contain SO₄ ²⁻ and become anoxic as a result of microbial decomposition.

Sulfate (SO₄ ²⁻), the most oxidized form of sulfur (+6), <u>is reduced</u> by these

sulfate-reducing bacteria. The end product of sulfate reduction is hydrogen sulfide, H₂S, (oxidation number -2) an important natural product that participates in many biogeochemical processes. The H₂S they generate is responsible for the pungent smell (like that of rotten eggs) often encountered near coastal ecosystems. When sulfate-reducing bacteria grow, the H₂S formed from SO₄ ²⁻ reduction combines with the ferrous iron to form black, insoluble ferrous sulfide, which is not toxic. This is important for the conservation of the environment.

b) The net ionic equation under acidic conditions is:

              4 H₂ + SO₄²⁻ + H⁺ → HS⁻ + 4 H₂O

    Global reaction:  SO₄²⁻ + 2H⁺ → H₂S + O₂
