The type of reproduction that is most often used by multicellular organisms is.

Nezavi [6.7K]

Meiosis is involved in the formation of the gametes of multicellular organisms.

<h3>How do multicellular organisms reproduce?</h3>

Both plants and animals reproduce by developing new individuals, through gametes or reproductive cells.

<h3>Characteristics of multicellular organisms reproduction</h3>

Many multicellular organisms always arise from a single cell called a zygote, the result of the union of two gametes (female and male).

The zygote subdivides rapidly throughout gestation, forming the entire body of the creature that, from its birth, begins to grow.

Therefore, multicellular organisms reproduce by means of certain types of reproductive cells that are generated and take care of building a complete new individual.

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 .

Deifferentiate between Catabolism and Anabolism.Explain with help of examples

Usimov [2.4K]

Answer:

Anabolism builds molecules required for the body's functionality. The process of catabolism releases energy. Anabolic processes require energy. ... Examples of catabolic processes are proteins becoming amino acids, glycogen breaking down into glucose and triglycerides breaking up into fatty acids.
