Answer:

The correct answer will be option-D.

Explanation:

Before Citric acid cycle or Krebs cycle, an intermediate reaction takes place which converts the pyruvate into Acetyl CoA. This reaction is known as pyruvate decarboxylation as it produces Carbon dioxide.  

Coenzyme A reacts with pyruvate which causes the release of two oxygen atoms and one carbon to form CO₂ along with the reduction of  NAD+ to NADH and produce "Acetyl CoA."

Thus,  option-D is the correct answer.

What two characteristics do fungi lack that forced them to become decomposers
Artist 52 [7]
Fungi are decomposers, they obtain their food from dead organic matters. Fungi obtain their nutrient this way because they can not produce their own food. To produce their own food they need chloroplast in their cells to obtain energy from the sun. And they also need the ability to fix nitrogen which they will incorporate into the food they produce. Because they lack the ability to do this thing, they have to adapt to eating dead materials. <span />
