Answer:
DNA Ligase
Explanation:
DNA ligase is an enzyme that connects nucleotides of DNA from the phosphate to the sugar. This seems to match the provided description, therefore I believe it to be the correct answer.
Answer:
The correct answer is - each macromolecule has its own function and role in the body of an organism.
Explanation:
There are four major macromolecules that are essential for the energy and growth and development of an organism, are Proteins, carbohydrates, fat and nucleic acids. Each macromolecule is essential and found in various food sources so any specific macromolecule can not found in a healthy diet.
Proteins play various roles in the body such as support, building blocks, carriers, enzymes, and hormones. On other hand, carbohydrate provides energy for the cells, the transmission of the genetic information will be transferred by a nucleic acid. Fat also helps provide insulation, make lipid membranes.
Answer:
The Citric Acid cycle and Electron Transport chain processes are part of a set of steps that occurs in cellular respiration.
During cellular respiration, a glucose molecule is gradually decomposed into carbon dioxide and water. Along the way, some ATPs are produced directly in the reactions that transform glucose. However, much later ATP is produced in a process called oxidative phosphorylation. Oxidative phosphorylation is fueled by the movement of electrons through the electron transport chain, a series of proteins incorporated into the inner membrane of mitochondria. Thus, Citric Acid cycle is responsible for degrading the acetyl CoA produced by previous reactions (glycolysis and pyruvate oxidation) producing four more carbon dioxide molecules, plus energized electrons and H + ions, which will be captured by NAD + and another acceptor. of electrons and hydrogen called FAD (Flavine Adenine Dinucleotide), originating NADH and FADH2 molecules. During this process, two GTP (Guanosine triphosphate - very similar to ATP) molecules are also formed. After this process, through the electron transport chain reaction NAD and FADH2 produced in the other steps deposit their electrons in the electron transport chain returning to the "pure" form (NAD + and FADH2). As electrons travel down the chain, energy is released that is used to pump protons out of the matrix, forming a gradient. Protons return to the matrix by means of an enzyme called ATP synthase, producing ATP. At the end of the electron transport chain, oxygen receives electrons and acquires protons to form water.
Explanation:
<span>The transcription of mRNA begins in the nucleus. The DNA is uncoiled and the nucleic acids with nitrogen bases adenine, thymine, guanine, and cytosine combine to form an incomplete mRNA. The current RNA contains exons (the coding region) and introns (non-informational regions). The introns are cut out and remaining exons are spliced together. Now the mRNA goes through polyadenylation. This is the process where the 3' end of the mRNA is attached with multiple adenine nucleotides. On the 5' end of the mRNA, a 5' cap is attached. This is the complete and functional mRNA. At this point, the mRNA exits the nucleus to join with the ribosome, ending the transcription and starting the process of translation. </span>
