Pyruvate kinase catalyzes the transfer of a phosphoryl group from phosphoenolpyruvate to ADP in the last step of glycolysis, for

ming pyruvate in the process. Vertebrates have several isozymes of pyruvate kinase, which can be allosterically inhibited by compounds including ATP and acetyl-CoA. What is an effect of cAMP-dependent protein kinase (PKA) inactivation of the liver isozyme but not the muscle isozyme?
A. Phosphate from the dephosphorylation of the liver isozyme is used to generate ATP and provide energy for movement.
B. Glycolysis is inhibited in the muscle, but not liver, when blood sugar is low.
C. Under stress (fight-or-flight) conditions, muscle can use glycolysis to break down glucose.
D. Glycogen synthesis is promoted in the liver as an energy store.

Answer:

The correct answer is under C under stress condition muscle can can use glycolysis to breakdown glucose.

Explanation:

Each and every metabolic process of our body remains under tight regulation by various compounds present inside our body.

   For example the catabolic process glycolysis is regulated by ATP,citrate,acetyl CoA etc.

     The cAMP dependent protein kinase inactivation of liver isozyme but not the muscle isozyme result in the occurrence of glycolysis in muscle during stress condition as gluconeogenesis cannot occur in muscle.

Ne4ueva [31]

Answer : The total mass of carbon dioxide and water produced will be, 65.7 grams.

Explanation :

Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The balanced chemical reaction will be,

C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O

According to the law of conservation of mass,

Total mass of reactant side = Total mass of product side

Total mass of C_6H_{12}O_6+6O_2 = Total mass of 6CO_2+6H_2O

As we are given :

Total mass of C_6H_{12}O_6+6O_2 = 65.7 grams

So,

65.7 grams = Total mass of 6CO_2+6H_2O

Therefore, the total mass of carbon dioxide and water produced will be, 65.7 grams.

hi, I need help with this question. Is it possible to determine the position and energy of an electron at the same time? why or
butalik [34]

Answer:

Explanation:

I searched it up:

"The Heisenberg uncertainty principle states that the exact position and momentum of an electron cannot be simultaneously determined. This is because electrons simply don't have a definite position, and direction of motion, at the same time! ... We know the direction of motion."

Hope this helps :D

Answer these questions based on 234. 04360 as the atomic mass of thorium-234. The masses for the subatomic particles are given.
nikdorinn [45]

The mass defect for the isotope thorium-234 if given mass is 234.04360 amu is 1.85864 amu.

<h3>How do we calculate atomic mass?</h3>

Atomic mass (A) of any atom will be calculated as:

A = mass of protons + mass of neutrons

In the Thorium-234:

Number of protons = 90

Number of neutrons = 144

Mass of one proton = 1.00728 amu

Mass of one neutron = 1.00866 amu

Mass of thorium-234 = 90(1.00728) + 144(1.00866)

Mass of thorium-234 = 90.6552 + 145.24704 = 235.90224 amu

Given mass of thorium-234 = 234.04360 amu

Mass defect = 235.90224 - 234.04360 = 1.85864 amu

Hence required value is 1.85864 amu.
