One substrate level phosphorylation occur in the citric acid cycle in the reaction catalyzed by succinyl CoA synthetase. Thus,option D is correct.

<h3>What is phosphorylation?</h3>

A process in which a phosphate group is added to a molecule like protein and sugar.

The first step is a condensation step,combining the two- carbon oxaloacetate molecule to form a six- carbon molecule of citrate.

Succinyl CoA synthetase is synthesized from alpha- ketoglutarate by alpha -ketoglutarate dehydrogenase through decarboxylation.

During this process addition of phosphate to an organic compound takes place.

Addition of phosphate to glucose to produce glucose monophosphate and phosphate combined with adenosine diphosphate to form adenosine triphosphate.

The main function of phosphorylation is the regulation of cellular processes like cell cycle and cell growth.

Therefore,succinyle CoA is the substrate that catalyzes one substrate level phosphorylation citric acid cycle reaction.Thus, option D is correct.

Lol pls help i really need help

C would be missing. because when secondary succession occurs, it was previously occupied and re-colonized. im almost positive because i kind of remember doing this a few weeks ago. hope this helps a bit!

anzhelika [568]

Crossing over occurs between homologous chromosomes, and is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.

----------------------------

There are different mechanisms involved in producing genetic variation among descendants. These are,

Crossing-over between homologous chromosomes (prophase 1),

Random lining of homologous chromosomes (metaphase 1),

Random fertilization

The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.

The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.

After crossing over, homologous chromosomes get separated again.

In the attached imaged there are four different stages of meiosis.

Stage C is the one that contributes the most to diversity.

We can see that crossing over has already occurred between homologous chromosomes, and they have already interchanged segments.

In the image you will see the difference between chromosomes that has gone through the crossing over mechanism, and chromosomes that has not. The difference in color represents segments interchange and variation.
