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.
Hi!
The answer is ribosomes.

The root nodules of leguminous plants houses nitrogen-fixing bacteria called Rhizobia. Rhizobia has a symbiotic relationship with leguminous plants that allows both to benefit from each other.
By binding to hydrogen, the Rhizobia bacterium is able to convert or fix nitrogen gas into ammonia , a form that the plant can use. Likewise, the legume plant provides the rhizobia bacterium with carbohydrate which the rhizobia depends on for energy. It is important to note that the carbohydrate sent to the nodules for the rhizobia is also what is used as a source of hydrogen to help the bacterium convert nitrogen to ammonia.
The fact that each plant gets only one allele from each parent plant is detailed in the law of law of segregation. Mendel found that each pair of alleles segregates independently of the other pairs of alleles during gamete formation. When sperm and egg unite at fertilization, each contributes its allele, restoring the paired condition in the offspring. The allele pairs separate or segregate during gamete formation, and randomly unite at fertilization.
