Question

Pyruvate oxidation takes place where in a cell

Answer 1

It happens in the mitochondrial network on the grounds that pyruvate is delivered by glycolysis in the cytoplasm.

Indeed, pyruvate oxidation occurs in the mitochondrial grid of eukaryotic cells.

When pyruvate enters the mitochondrial lattice in eukaryotes, it is oxidatively decarboxylated (with the assistance of the catalyst PDH) to frame Acetyl CoA.

Answer 2

" Photosynthesis "

It is the process by which green plant and some other organism use sunlight to synthesize nutrients from carbon dioxide and water.

The main product form here is glucose and by products are oxygen and water.

Here it takes place in chlorophyll and I'm presence of sunlight.

There are two stages of photosynthesis :

1. Light reactions :

It occurs in the grana where photon are absorbed so as to excite electrons of chlorophyll to a higher energy level. These activated elctrons are harnessed to form ATP from the ADP and reduce NADP to NADPH. Wayer ia also spotted here and oxygen is released.

2. Dark reactions :

Calvin cycle occurring in chlorophyll here carbon combine with 5-carbon sugar called ribulose biphospahte. This unstable compound breaks down into 3-carbon compound. This then forms glucose.
