Adenosine triphosphate (ATP) is the main energy currency used in cells. ATP hydrolysis is coupled with unfavorable reactions, ma

king the net change in energy for the set of reactions less than 0, which is favorable. Although ATP is the main energy currency, other molecules can fulfill this role and take part in coupled reactions. Determine whether each of the phrases or examples describes a thioester, reduced cofactor, or phosphorylated compound.Acetyl COA, Ubiquinol, Phosphocreatine, the Sulfur-Carbon bond is hydrolyzed, These compounds yield H2P04- upon hydrolysis, These compounds accept e- during the oxidation of substrates and energy is released when they are oxidized. Please sort those phrases under "thioester," "reduced cofactor," or "phosphorylated compound," and explain why for each choice!

Answer:

<em>Thioesters- the Sulfur-Carbon bond is hydrolyzed, e.g. AcetylCoA</em>

<em>Reduced cofactor- These compounds accept electrons during the oxidation of substrates and energy is released when they are oxidized, e.g. Ubiquinol</em>

<em>Phosphorylated compounds- These compounds yield H₂P0₄⁻ upon hydrolysis, e.g. Phosphocreatine</em>

Explanation:

<em>Thioesters</em><em> are esters in which the linking oxygen atom is replaced by a sulphur atom. </em>They are the product of esterification between a carboxylic acid and a sulfhydryl group (thiol). They have the functional group R–S–CO–R'. Thioesters are common intermediates in many biosynthetic reactions. Examples include malonyl-CoA, acetyl-CoA, and propionyl-CoA. <em>In the hydrolysis of thioesters, the sulfur-carbon bond is hydrolyzed.</em>

<em>Cofactors</em><em> can be either organic or inorganic molecules that are required by enzymes to function. Cofactors can be oxidized or reduced for the enzymes to catalyze the reactions.</em>  Examples include, NAD, FAD, NADP, <em>Coenzyme Q₁₀.</em> Coenzyme Q₁₀ exists in three redox states, fully oxidized, partially reduced, and fully reduced. Ubiquinol is the reduced (electron-rich) form of coenzyme Q₁₀. Coenzyme Q₁₀ is vital for proper transfer of electrons within the mitochondrial oxidative respiratory chain, whose main function is to produce adenosine triphosphate (ATP). <em>These compounds accept electrons during the oxidation of substrates and energy is released when they are oxidized. </em>

Phosphorylated compounds are compounds with a phosphoryl group (PO₃²⁻) attached to its molecules. <em>These compounds yield an inorganic phosphate (H₂P0₄⁻) upon hydrolysis</em>. Phosphorylation is especially important for protein function as this modification activates or deactivates almost half of the enzymes, thereby regulating their function. Examples include, glucose-1-phosphate, phosphoserine, phosphocreatine, etc.

How many atoms are in 5.2 moles of Na ?
Nastasia [14]

One mole of a substance is defined by Avogadro as consisting of 6.022 x 1023 atoms. This is Avogadro's number. To calculate the number of atoms in two moles of sodium, use dimensional analysis. 2.0 moles Na x 6.022⋅1023g1mol=1.20⋅1024 atoms of Na

In the city a street peddler offers you a diamond ring for 30 bucks how can you test the rock
larisa86 [58]

Explanation:

Hardness test — Scratch the rock with a fingernail, a copper penny, a glass plate or nail, and a ceramic plate. Check your Guide to assign it a rating on the Mohs Scale of Hardness.

Color streak test — Test for the “color streak” of the minerals by rubbing the rock across the ceramic plate in the Mineral Test Kit, or across smooth

cement. Look up which colors indicate which minerals are present.

Magnetism test — Hold the magnet in the Mineral Test Kit near your rock. If there is a magnetic pull, it has a metal mineral in it.

Acidity test — Put vinegar in the bottle included in the Mineral Test Kit. Squeeze out a few drops on the rock. If it fizzes, it contains carbonate.

A quick and easy way to find out whether your diamond is real or fake: try fogging it up with your breath. If it clears up after one or two seconds, then your diamond is real, but if it stays fogged for three to four seconds chances are that you're looking at a fake.
