The correct option is D.

Metals have different properties which are utilized in diverse ways to meet the need of man. One of the properties of metals is thermal conductivity. Thermal conductivity refers to the ability of the metal to conduct heat. This property is especially useful in the working of electric pressing iron. The heat released by the metal that is used in the manufacturing of the iron is regulated by mean of thermostat, which keep the heat constant in order to protect the clothes been ironed from damage.

It would most likely be D. Thermal conductivity, as the metal used in ironing is able to conduct heat and allow ironing to be done.

Which best describes nuclear energy?
svet-max [94.6K]

Answer:

The correct answer is - D.  the energy stored inside the center of an atom.

Explanation:

Each atom has a small center in it called the nucleus and the energy that holds the nucleus or center of the atom together in the atom is known as nuclear energy.

It is the energy that is stored in the center of the atom and normally does not come out, however, in some radioactive atoms the sends some part of the energy as radiation.

Thus, the correct answer is - D.  the energy stored inside the center of an atom.

15. The mass of a sample of iron is 114 g, and the density of iron is 7.86 g/cm3. What is the volume of this iron sample?
anyanavicka [17]

Answer:

The answer is

<h2>14.50 cm³</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}

From the question

mass of iron = 114 g

density = 7.86 g/cm³

The volume is

volume =  \frac{114}{7.86}  \\  = 14.50381679

We have the final answer as

<h3>14.50 cm³</h3>

Hope this helps you

Answer:

Breakdown of glucogen.

Glycogen phosphorylase of muscle and liver, which catalyzes the reaction

(Glucose)n + Pi ----> (glucose) n-1 + glucose 1-phosphate

Shortened glycogen chain

* acyl-CoA dehydrogenase

Dehydro genation of fatty acyl–CoA produces a double bond between the alpha and beta carbon atoms

Regulatory Enzyme of fatty acid breakdown

*Pyruvate dehydrogenase complex

Pyruvate derived from glucose and other sugars by glycolysis, is oxidized to acetyl-CoA and CO2 by the pyruvate dehydrogenase (PDH) complex, located in the mitochondria of eukaryotic cells and in the cytosol of bacteria.

Pyruvate converted to acetyl CoA

*Citrate synthase

The first reaction of the citric acid cycle is the condensation of acetyl-CoA with oxaloacetate to form citrate, catalyzed by citrate synthase:

Citric acid cycle.

* Lactate dehydrogenase

When animal tissues cannot be supplied with sufficient oxygen to support aerobic oxidation of the pyruvate and NADH produced in glycolysis, NAD+ is regenerated from NADH by the reduction of pyruvate to lactate.

Anaerobic respiration

*Phosphofructokinase

Glucose 6-phosphate can flow either into glycolysis or through any of several other pathways,

including glycogen synthesis and the pentose phosphate pathway. The metabolically irreversible reaction catalyzed by PFK-1 is the step that commits glucose to glycolysis.

Regulatory enzyme of glycolysis

*succinate dehydrogenase

Part of both the citric acid cycle and oxidative phosphorylation

*adenylate cyclase

Converts ATP to cAMP

*Glucose 6-phosphate dehydrogenase

Glucose 6-phosphate dehydrogenase catalyzes the first step in the pentose phosphate pathway, which produces NADPH.

Pentose phosphate pathway

*Glucose 6-phosphatase

Glucose 6-phosphate is dephosphorylated by glucose 6-phosphatase to yield free glucose.
