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 .

If a 2 kg ball is traveling at a speed of 4 m/s, what is its kinetic energy?

MariettaO [177]

Answer:

Option D is the correct answer.

Explanation:

It is given that a 2 kg ball is traveling at a speed of 4 m/s, so we have to find its kinetic energy.

KE = 1/2 mv²

KE = 1/2 × 2×(4)²

KE = 1/2 × 2×16

KE = 16 J

<u>Some information about Kinetic Energy</u>.

Kinetic Energy is the energy an object has because of its motion. It is directly proportional to the velocity of the particle and its mass. Kinetic energy is given by,

KE = ½mv²
It occurs due to the motion of the particle.
If a particle at rest position, then the kinetic energy will be zero because that particle won't be accelerating.

Why do you think a small surface area to volume ratio would cause a problem?

Scilla [17]

Answer:

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.

Choose all that apply.

Elodia [21]

The correct answers are options:

1. Amphibians evolved before land reptiles.

4. Elephants appear in the fossil record after dinosaurs became extinct.

The relative dating is a technique of dating with respect to any past event. In this case, two events are discussed to be occurred in a sequence related to one-another. In the option 1, the amphibians are said to be evolved before reptiles. So, the evolution of the amphibians is relatively dated with the evolution of reptiles. Same in the option 4, the evolution of the elephants is relatively dated with the extinction of the dinosaurs.

What type of rock is formed from compaction or cementation?

Marina CMI [18]

Sedimentary rocks are formed by cementation and compaction. This happens when sediment particles are compressed and fused together over very long periods of time.
