All of the following contribute to the movement of venous blood EXCEPT A. ventricular systole B. pressure changes in the thorax

AlladinOne [14]

Answer: B. pressure changes in the thorax

Explanation:

The veins are the blood vessels which returns the deoxygenated blood from all the tissues and cells of the body back to the heart. The ventricular systole, venous valves, activity of the skeletal muscles and neural control over venoconstriction all influence the movement of the blood in the venous.

The pressure changes in the thorax occurs due to inspiration and expiration. During the process of inspiration, the diaphragm below the lungs contracts and moves downward while the muscles of the ribs pulls downward. When the size of the thoracic cavity increase the air pressure inside the cavity decreases and vice-versa. The pressure inside the thoracic cavity is not related with the movement of the venous blood as it regulates the exchange of the gases not the blood.

The central dogma states that information flows from

IgorC [24]

Information is encoded in DNA, then copied onto RNA during transcription. Then, ribosomes convert the information carried in RNA into a protein, in the process of translation. Also, A and D could be ruled out because DNA and RNA are solely involved with proteins, but polysacchariades are chains of sugars.

Pyruvate dehydrogenase is regulated by feedback inhibition and covalent modification. Which molecules inhibit the pyruvate dehyd

Oksi-84 [34.3K]

ADP, NAD+, CoA-SH, and pyruvate are the molecules that inhibit the pyruvate dehydrogenase complex.

<h3>What is pyruvate dehydrogenase complex?</h3>

PDC3 triggers the oxidative decarboxylation of pyruvate, resulting in the creation of acetyl-CoA, CO2, and NADH.

The PDC plays a crucial role in the oxidation of glucose by connecting the glycolytic pathway to the tricarboxylic acid cycle's oxidative pathway.

ADP, NAD+, CoA-SH, and pyruvate all inhibit it. PDK prevents glycolysis from being coupled to GO by inhibiting its target enzyme PDH.

Thus, the answer is ADP, NAD+, CoA-SH, and pyruvate .
