The answer is “it is the gap between neurons” and “it ensures that information travels in one direction only.”
Answer:
Option (a).
Explanation:
Homozygotes individuals has the same genotype whereas the genotype of the heterozygotes are different. The homozygotes may refer the true or pure organism.
The gametes obatined from the homozygotes caaries the same gene. The gametes of the heterozygotes carries the different version of the gene. The dominant trait will express themselves in the heterozygotic condition.
Thus, the correct answer is option (a).
More water means more pee (theoretically). Pee is actually just garbage materials from the body (toxins). These color the urine. The more you drink, the more you have to pee and just pee clean because all toxins are out, or you have more water to take out the toxins, having less of it per let's say 0.5 l
Answer:
A. NADH and FADH2 both donate electrons at the same location.
Explanation:
In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.
These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.
Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.
NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.
The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.
If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.
