The number of ATPs that will be made in the complete oxidation of arachidonic acid is 155.

There are 9 β-oxidation cycles for complete oxidation of arachidonic acid (it has 20 carbon atoms).

Arachidonic acid has 20 carbon atoms and four double bonds (see picture below).

One β-oxidation (beta-oxidation) cycle produces 1 NADH, 1 FADH2, and 1 acetyl CoA (sea the picture below).

For 9 cycles: 9 NADH, 9 FADH2, and 10 acetyl CoA.

NADH and FADH2 enter Electron Transport System (ETS) cycle to generate 3ATP and 2ATP respectively.

Acetyl CoA enter into tricarboxylic acid cycle (TCA) and each CoA gives 12 ATP.

9 NADH = 9 x 3 = 27 ATP

9 FADH2 = 9 x 2 = 18 ATP

10 acetyl-CoA = 10 x 12 = 120 ATP

Net yield of ATP = 27 ATP + 18 ATP + 120 ATP -2 ATP - 8 ATP (it has four double bonds)

Net yield of ATP = 155 ATP

Answer:

0.0872g

Explanation:

Since mg is smaller than g, you will have to multiply the mg by milli which is equal to 10⁻³.

87.2 × 10⁻³ = 0.0872 grams

A cup of coffee contains 87.2 mg of caffeine. The number of grams  present in the cup of coffee is 0.0872g.

Grams and milligrams are the measurement units that measure the amount or quantity of matter. It measures the solid mass and the quantity of matter. It is the SI unit of mass. There are seven units of measurement.

These units are Length - meter (m), Temperature - kelvin (K), amount of substance - mole (mole), Luminous intensity - candela (cd), Electric current - ampere (A), Mass - kilogram (kg), Time - second (s).

Here the mass of caffeine is asked in grams, which are given in milligrams.  

As we know, 1 gram is = 1000 milligrams.

0.0872g = 87.2 mg

Thus, the number of grams present in the cup of coffee is 0.0872g.

what is specific heat capacity?

"The amount of heat required to change the temperature of a unit mass of the substance by one degree" is the definition of specific heat capacity for any substance. This is expressed as: Specific heat capacity is a sort of thermal inertia since it shows how resistant a substance is to changes in temperature.

Water has a specific heat capacity of about 4.2 J/g°C. As a result, to increase 1 gramme of water by 1 degree Celsius, 4.2 joules of energy are required.

By formula,

Q = mcΔT = 32*4.2*42 = 5644.8 J

One calorie= 4.184 joules

thus, Q = 5644.8/4.184 calorie = 1349.13 calories.

When water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into solution. The property of water that accounts for this occurrence is the polarity of water.

The water molecule is made up of one oxygen atom and two hydrogen atoms. The three atoms are arranged in such a way that the hydrogen atoms carry a partial positive charge, and the oxygen atom carries a partial negative charge.

Thus, there is a tendency for the partial negative oxygen atom to be attracted to the positively charged portion of another substance, and the partial positive hydrogen atoms to be attracted to the negative portion of the substance.

This attraction is called polarity. A substance is said to be polar when it carries both a positive and negative charge in its neutral state. Hence water dissolves a substance when weak charges on the water molecule attract the oppositely charged portion of that substance due to its polarity.

In chemistry, polarity is the separation of electric charge, which causes a molecule or its chemical groups to have an electric dipole moment, with a negatively charged end and a positively charged end.

Due to a difference in electronegativity between the bound atoms, polar molecules must have one or more polar bonds. If the bond dipoles cancel each other out through symmetry, molecules with polar bonds have no molecular polarity.

Dipole-dipole intermolecular forces and hydrogen bonding are two ways that polar molecules communicate with one another. Surface tension, solubility, melting and boiling points, as well as other physical characteristics, are all governed by polarity.

4.6 ml of a 5.0 M solution of sodium borate must be added to a 200 ml solution of 50 mM boric acid in order for the pH to be 9.6.

Henderson–Hasselbalch equation for buffer solution:

pH = pKa + log(cs/ck)

pH = 9.6; pH of the buffer solution of sodium borate and boric acid

pKa = 9.24

log(cs/ck) = 9.6 - 9.24

log(cs/ck) = 0.36

cs/ck = 2.29; ratio of sodium borate and boric acid

nk = 0.05 M × 0.2 l

The bonding of water molecules to each other with hydrogen bonds is called hydrogen bonding.

In chemistry, hydrogen bonding is crucial as it holds water molecules together tightly.

Individual water molecules are made up of oxygen and hydrogen atoms which are linked together through covalent bonds.

While adjacent molecules are attached to each other through electrostatic attractions called hydrogen bonding.

Moreover, a water molecule is a dipole substance as uneven sharing of electrons creates two poles on it. One is on the hydrogen atom which is positively charged and the other is on the oxygen atom which is negatively charged. Overall it's a neutral compound.

When comparing two hydrocarbons, the larger, higher molecular weight molecule would have a higher melting point due to greater amounts of dispersion forces.

Hydrocarbons are organic compounds made up of only carbon and hydrogen. They are non-polar molecules; therefore, they do not have partial charges or hydrogen bonds. The only form of intermolecular attraction between them are dispersion forces.

Dispersion forces are the weakest type of intermolecular forces. They exist in non-polar molecules and gases like neon, hydrogen gas and oxygen gas. It is formed by the attraction between electrons and the nucleus.

Hydrocarbons with higher molecular weights have more electrons surface area than hydrocarbons with lower molecular weights. This causes the dispersion forces between the molecules to increase, thereby causing an increase in boiling point.

mass of carbon in the carbon dioxide, C = (12 x 2.45)/44 = 0.668 g

note molar mass of carbon dioxide = 44 g/mol

mass of hydrogen in the water, H = (1 x 1.5)/18 = 0.083 g

note molar mass of water = 18 g/mol

mass of oxygen, O = 2.62 g - (0.668g + 0.083 g) = 1.869 g

H = 0.083 g/ 1 = 0.083 mole

O = 1.869 g/16 = 0.1168 mole

Divide through by the smallest number of mole

C = 0.056/0.056 = 1

H = 0.083/0.056 = 1.5

According to the atomic radius, the largest atom or ion in each grouping are – [tex]S^2^-[/tex], [tex]Mg[/tex] , [tex]Sb[/tex] , [tex]Ca[/tex] , [tex]Na[/tex] .

A measure of the size of an atom is the atomic radius of a chemical element, which is normally the average distance between the core of the nucleus and the outermost isolated electron. There are several non-equivalent descriptions of atomic radius since the border is not a clearly defined physical object.

Since the net nuclear charge steadily rises as a result of higher electron attraction to the nucleus, the radius of atoms decreases across a period. However, as the number of shells in each atom grows along the group, the atomic radius increases.

Neutral atoms typically become larger down a group and smaller across a period. The radius of a neutral atom increases or decreases as it acquires or releases an electron, becoming an anion or cation, respectively.

In the given groupings, the size of the atoms and ions according to the atomic radius is as follows:

Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.

One or more terms as well as the derivatives of the dependent variable in respect to the independent variable make up a differential equation (i.e., independent variable) dydx. = f (x) The independent variable in this case is "x," while the dependent variable is "y." For instance, dydx.

The chemical force most directly responsible in the given case is hydrophobic interactions.  

The interactions between hydrophobes and water, or low water-soluble compounds, are illustrated by the hydrophobic interactions. Nonpolar hydrophobes often have a longer carbon chain than polar molecules and do not interact with the water molecules. By removing a peptide from the N terminus of trypsinogen, it can become trypsin, which allows a salt bridge to develop between the new N-terminal.

The trypsin "activation domain" undergoes a conformational shift in response to the development of this salt bridge, resulting in the establishment of the oxyanion hole and S1 binding site. Trypsinogen activation thus seems to be an illustration of protein folding influenced by electrostatic interactions. The activation domain receives 5 kcal/mol of stabilization energy through hydrophobic interactions with the Ile16 side chain.
