Answer:
begins in the mouth(ptyalin converting carbohydrate to maltose), stops in the illeum (secretion of amylase) and Is completed in the body cells(to release energy)
Answer: b. Acetyl Co-A
Explanation:
Acetyl CoA produced through pyruvate, amino acids, and fatty acids are oxidized in the Krebs cycle in CO2, obtaining as products NADH, FADH2 and GTP (ATP). Parallel to this oxidation, the Krebs cycle produces compounds used as precursors for biosynthesis. As it is a cycle, an oxaloacetate molecule could, in principle, oxidize an amount indefinite of acetyl CoA. Acetyl-CoA is formed from the oxidative decarboxylation of pyruvate, sequentially performed by pyruvate dehydrogenase -PDH (complex multi enzymatic of 3 enzymes), in the mitochondrial matrix.
Answer:
The TATA box is an alternating sequence of Adenine and Guanine nucleotides that transcription factors bind to. The TATA box is found just before a gene. The transcription factors tell the RNA polymerase where to bind to begin transcription. This ensures the RNA polymerase will know where to start and which gene to transcribe.
Explanation:
Answer:
ion even know what this means
Explanation:
Ans. (4). protein synthesis.
Protein synthesis can be defined as a process that involves formation of polypeptides or proteins by using information present in DNA. It is divided into two steps, transcription and translation.
During transcription, DNA is transcribed into mRNA and information present in DNA is transferred to mRNA as codons. Codons represent triplet of nucleotides and each codon codes for a specific codon.
Translation involves formation of protein, during which amino acids are added to the growing polypeptide chain with the help of codons.
The given diagram represents process of translation. Thus, the correct answer is option (4).
