Kinetic energy! is the motion e energy
Answer:
The correct answer is B. pyruvate
Explanation:
In glycolysis, glucose is oxidized to produce 2 molecules of NADH, ATP, and pyruvate. Then this pyruvate molecule is used in the Kreb cycle and gets fully oxidized into carbon dioxide and water.
This oxidation of pyruvate molecule gives rise to more NADH and FADH₂ molecule. These molecules are reduced form of energy which is used as a source of electron during oxidative phosphorylation to produce more ATP molecules.
Therefore pyruvate is the useful product of glycolysis which is utilized to give energy to the cell in the form of ATP.
Answer:
D) can allow the production of different proteins from a single gene.
Explanation:
Alternative splicing:
Alternate splicing is also known as alternative RNA splicing, or differential splicing. Alternate splicing is a regulated process during gene expression in which multiple proteins are produced from single gene.
Actually eukaryotic genes have both Intron and exon sequences. Exons are the sequences present inside mRNA which convert into amino acids and produces peptides while introns are the sequences which are spliced (cut) from pre mRNA.
Some time introns for some proteins becomes exons for other proteins in this ways one gene can produce multiple proteins.
(4) organic catalysts
The job of catalysts in chemical reactions is to make the reaction go faster by lowering the amount of energy needed to activate the reaction. If less energy is needed for the reaction to occur, then the reaction can go faster because a large energy build-up is not needed.
Answer:
NAD+ and FAD+
Explanation:
NAD+ and FAD+ are the electron acceptors in the breakdown pathways. As NADH and FADH2, these carriers transport high-energy electrons to the electron transport chain where the electrons power the production of ATP.
