Pyruvate is a direct precursor of anapleurotic reactions which produce which intermediates of the tca cycle?

Biology
1 answer:
Virty [35]3 years ago
7 0

The correct answer is:  oxaloacetate

Anaplerotic reactions are chemical reactions that form intermediates that can be used in the further steps of metabolic pathways. These reactions are very important, because it is crucial for the cell to regulate concentrations of TCA cycle metabolites and intermediates.

The reaction in which pyruvate is converted to oxaloacetate is catalyzed by pyruvate carboxylase and it occurs in mitochondria. Also, pyruvate can be converted to L-malate, in a similar way.

¿Como se sintetiza una proteína?
Arisa [49]
La síntesis de proteínas se realiza en los ribosomas situados en el citoplasma celular. En el proceso de síntesis, los aminoácidos son transportados por ARN de transferencia correspondiente para cada aminoácido hasta el ARN mensajero donde se unen en la posición adecuada para formar las nuevas proteínas.

As blood pressure increases and the hearts is working harder the most vulnerable arteries area? Located near the heart, because
KIM [24]

As blood pressure increases and the hearts is working harder the most vulnerable arteries area are those <u>Located near the heart, because they are absorbing the most shock.</u>

<u></u>

Explanation:

When the heart pumps blood, the highest pressure is felt close to the heart. This is why the aorta, the artery that carries blood away from the heart is made up of thick walls to withstand this pressure, otherwise, these vessels would rupture. Away from the heart, this pressure lessens, and the blood vessels are not so thick-walled.

What is the approximate rate of plate movement??
VikaD [51]
<span>Some sources stated that in the North Atlantic, the rate of movement is only about 1 cm (about 0.4 in) per year, while in the Pacific it amounts to more than 4 cm (almost 2 in) annually, while two others said the plates, in general, traveled from 5 to 10 cm/yr.</span>

Describe the chemical make up and type of bonding found in water molecules?
andre [41]
Water molecules consist of 2 Hydrogen and 1 Oxygen atom. They are bonded by a polar covalent bond, meaning the electrons shared by the covalanet bonds are not evenly distributed. Oxygen is more electronegative than Hydrogen and will pull the electrons from its bonds with Hydrogen closer to itself. Thus results in a partial positive dipole on the Hydrogen of the water molecule and a partial negative dipole on the Oxygen of the water molecule. These partial charges allow water to hydrogen bond with one another through a process called cohesion.

Water, H2O, and methane, CH4, are both covalent substances. Why is water a liquid at room temperature while methane is a gas? A
tino4ka555 [31]

The right answer is D.

Intermolecular forces lead to the assembly of microscopic systems. They are responsible for the cohesion of matter in most macroscopic phases. These are weak forces compared to covalent bond strengths. They do not modify the nature of the molecular species and only influence their mode of assembly. The most well-known intermolecular bonds are the Van der Waals bond and the hydrogen bond.

The greater the intermolecular forces, the more the aspect of the element will tend to be more condensed (gas <liquid <solid).
