Answer:
The correct answer will be- Protons pumped by the NADH through inner mitochondrial membrane is greater than the protons pumped by the FADH₂.
Explanation:
During the cellular respiration, the electron donors like NADH and FADH₂ are produced which donates the electrons during the electron transport chain.
The NADH molecule contains high energy electron which transmits the electron to complex I. This releases a large amount of energy utilized to pump H⁺ ions from matrix to intermembrane space.
Similarly, the FADH₂ contains low energy electrons as compared to the NADH so fewer protons are pumped to intermembrane space.
Since NADH pumps a large number of protons that is 10 protons whereas FADH₂ pumps only 6 protons and four protons are required to form the ATP therefore, NADH produces about 2.5 ATP whereas FADH₂ forms 1.5 ATP.
Thus, Protons pumped by the NADH through the inner mitochondrial membrane is greater than the protons pumped by the FADH₂ is the correct answer.
The answer for this question is True
Answer: C
Explanation:
In substrate level phosphorylation energy is trapped directly from the substrate, without the help of the complicated electron transport chain reactions.
Substrate-level phosphorylation refers to the formation of ATP from ADP by directly phosphorylating ADP from a high energy substrate catalyze by an enzyme.
But when energy is trapped by oxidation of reducing equivalents such as NADH, it is called oxidative phosphorylation.
Examples of substrate level phosphorylation in glycolysis include conversion of 1, 3-Bisphospho glycerate to 3-Bisphospho glycerate and conversion of phospho enol pyruvate to pyruvate
Answer:
The movement of the plates can contribute to the natural selection of organisms.
Explanation:
Processes such as mutations, duplications, exon shuffling, transposable elements and pseudogenes have contributed to genomic evolution.
