The oxidation of pyruvate is not the only process that generates acetyl-CoA. In particular, fatty acids are broken down through

oxidation, generating a great deal of acetyl-CoA, which can also enter the TCA cycle to generate high energy molecules. Is there a difference between between the TCA cycle using acetyl-CoA generated from fatty acid oxidation compared to that generated from carbohydrate oxidation?
A. The concentration of malate increases when reacting with acetyl-CoA derived from a fatty acid,
B. A molecule of acetyl-CoA derived from a fatty acid generates more FADH2 than acetyl-CoA from
C. A molecule of acetyl-CoA derived from a carbohydrate generates more NADH than acetyl-CoA but not when reacting with acetyl-CoA derived from a carbohydrate. WI derived from a carbohydrate derived from a fatty acid.
D. There is no difference in the TCA cycle, regardless of the source of acetyl-CoA.

Answer:

The correct answer is D. There is no difference in the TCA cycle,regardless  of source of acetyl CoA.

Explanation:

Acetyl CoA is the central metabolite of aerobic respiration.Acetyl CoA is generated from both decarboxylation of pyruvate and from the beta oxidation of fatty acid in mitochondrial matrix.

            In both cases the generated Acetyl CoA molecule is same but it comes from different source.

  If the Acetyl CoA generated from beta oxidation of fatty acid enter into the TCA cycle it will generate same molecules of NADP and FADH2 as that of Acetyl CoA generated from carbohydrate metabolism

Why are the alkali metals and the halogens very reactive
jeyben [28]

Answer:

Answer in explanation

Explanation:

The reactivity or passiveness of an element depends solely on how close it is to attain a noble gas configuration. This means the closer an element is to attain a noble gas configuration, the greater its reactivity in both direction, positively or negatively.

Alkali metals belong to group 1 of the periodic table while halogens belong to group 17 of the periodic table. This means they are just one electron away from achieving the stability of a noble gas configuration. While alkali metals need to lose one electron to form a univalent positive ion, halogens news to gain one electron to form a univalent negative ion.

They tend to go about this vigorously and as such undergo several chemical reactions because of that single electron they neeed.

How much heat is required to melt 26.0 g of ice at its melting point?
MAXImum [283]

Answer:

Heat required to melt 26.0 g of ice at its melting point is 8.66 kJ.

Explanation:

Number of moles of water in 26 g of water: 26× \frac{1}{18.02} moles

                                                                      =1.44 moles

The enthalpy change for melting ice is called the entlaphy of fusion. Its value is 6.02 kj/mol.

we have relation as:

                                           q = n × ΔH

where:

q  = heat

n  = moles

Δ H  = enthalpy

So calculating we get,

                                        q= 1.44*6.02 kJ

                                        q= 8.66 kJ

We require 8.66 kJ of energy to melt 26g of ice.
