All of the above are correctly matched.
Glycolysis is the process wherein glucose (from the diet) is broken down to two molecules of pyruvate through a 10-step enzymatic reaction. This reaction occurs in the cell's cytoplasm or cell body. Once pyruvate is formed, the pyruvate dehydrogenase complex, an enzyme complex responsible for converting pyruvate into acetyl-CoA.
Acetyl-CoA will then be transported to the mitochondria and it will cycle through series of reduction-oxidation reactions in the Kreb's cycle (also known as the tricarboxylic acid cycle or the citric acid cycle). Various reducing compounds (NADH and FADH2) are formed and these reducing compounds are oxidized, still, in the mitocondria in the electron transport chain producing ATP via oxidative phosphorylation.
Answer: Gdy uzależnienie od alkoholu lub narkotyków się utrzyma, staje się priorytetem w życiu człowieka. Gdybyście byli uzależnieni, spędzilibyście więcej czasu i pieniędzy na nabywaniu i używaniu narkotyków.
Explanation:
Answer:
The correct answer will be- Meiosis I, anaphase I
Explanation:
Alleles are the variant alternative forms of a gene which determines the trait of an organism. The trait or phenotype is expressed only when the two alleles controlling a single trait on separate chromosomes are aligned in a complementary position.
During gamete formation, the alleles controlling a trait segregate independently of each other. This segregation of alleles takes place during Anaphase I of meiosis I. During anaphase, the sister chromatids are separated by the mitotic spindles so that the chromosomes can reach the opposite poles.
Thus, Meiosis I, anaphase I am the correct answer.
Answer: Eating excessive quantities of such molecules could deregulate this process, increasing methylation and repressing the expression of genes that should normally be expressed.
Explanation:
DNA methylation is one of the epigenetic mechanisms involved in the regulation of gene expression, because it is a process by which methyl groups are added to DNA.
Methylation then modifies the function of DNA when it is found in the promoter gene, it is essential for normal development and is associated with a number of key processes, including genomic imprinting, inactivation of the X chromosome, repression of repeating elements, aging, and carcinogenesis. Usually, <u>it acts to suppress gene transcription.</u>
For example, folic acid is essential for the rapid cell division that occurs during early fetal development and it also plays an important role in methylation and thus in gene regulation. <u>The metabolism of these vitamins is aimed at achieving adequate levels of DNA methylation, necessary for the cellular processes</u>. Eating excessive quantities of such molecules could deregulate this process, <u>increasing methylation and repressing the expression of genes that should normally be expressed</u>.
