Answer:
(D) acetyl CoA, NADH, H+, and CO2.
Explanation:
The given explanation is about oxidative decarboxylation of pyruvate into acetyl CoA and carbon dioxide. The reactions are catalyzed by enzyme complex pyruvate dehydrogenase. During the reaction, pyruvate loses one of its carbon atoms in the form of CO2 and the rest of two carbons form the acetate which in turn combines with CoA to form the acetyl CoA.
Since it is an oxidative decarboxylation, the released electrons are accepted by NAD+ which in turn is converted into NADH + H+.
Overall, there is the formation of one molecule of acetyl-CoA, CO2 and NADH + H+ each from one molecule of pyruvate.
Answer:
The nuclear membrane dissolves, and spindle fibers form.
Explanation:
This occurs during prophase. the chromosomes become shorter and thicker. The centrioles migrate to the opposite poles. The nuclear envelope is broken down, the nucleolus disappears, and microtubules attach to the chromosomes at the kinetochores present in the centromere. Microtubules that are associated with the alignment and separation of chromosomes are referred to as spindle fibers. Chromosomes visible under a microscope are connected at the centromere. In meiosis, the homologous chromosomes break in their DNA strands at the same point, following a recombination of the fragmented parental DNA strands into non-parental combinations, known as crossing over.
