Answer:
C
Explanation:
pyruvate dehydrogenase is the enzyme which catalysis pyruvate to acetyl Co -A. Thus,it ensures the formation of link reaction/ bridge reaction for linking glycolysis with Citric acid cycle. Therefore, inhibition of this enzyme, prevent link reaction, and there reduction in pyruvate utilization and therefore prevent the commencements of Citric acid cycle, with consequent reduction in glucose oxidation. as there is no reaction of acetyl Co A (from link reaction from pyruvate ) with 4C oxaloacatate in the kreb Cycle to form Citrate in Kreb's cycle. Thus the heart depends on fatty acid supply for energy.
Answer:
They help you live longer
Explanation:
Research has shown that social connections not only impact your mental health, but your physical health as well. A review of 148 studies (308,849 participants) indicated that individuals with stronger social relationships had a 50% increased likelihood of survival.
Answer:
Transcription and RNA processing (splicing)
Explanation:
Although Howard is almost right, the DNA sequence does not precisely relate to the protein sequence. First of all, the DNA is transcribed to an primary mRNA molecule. Bur before the mRNA is ready to be translated into an amino acid sequence, it must be processed into a mature mRNA.
This includes adding a 3' poly A tail, and a 5' cap, and importantly for this question, splicing.
Splicing is the removal of non protein coding intermediate sequences called introns from the protein coding regions (exons) of a primary mRNA. This means that lots of the DNA sequence is not dictated by the final protein, as many of the intervening sequences have been removed by splicing.

Answer:
e. infection causes lymphocytes to divide more rapidly
Explanation:
The cell cycle includes interphase and M phase which in turn together produce daughter cells from the existing parent cells. DNA replication occurs during the S phase of interphase to ensure that the daughter cells obtain the identical DNA present in the parent cell.
Lymphocytes are one of the types of white blood cells and are involved in cell-mediated and antibody-mediated immune responses. These cells are present in the blood as well as in lymphatic tissues. During the given experiment, lymphocytes exhibited a higher rate of incorporation of labeled nucleotide after the introduction of a pathogen in the culture. This suggests that the introduction of pathogen triggered the cell division in lymphocytes to produce more lymphocytes to fight the infection.
