Answer:
It lacks a cytochrome oxidase for passing electrons to oxygen.
Explanation:
During aerobic respiration, the NADH and FADH2 formed during glycolysis and Kreb's cycle are oxidized through the electron transport chain. NADH and FADH2 pass their electrons to the molecular oxygen via four complexes electron transport chain. Cytochrome oxidase is also called a complex IV of the electron transport chain. It serves to carry the electrons from cytochrome c to molecular oxygen, reducing it to H2O.
In the absence of cytochrome oxidase, electrons from NADH and FADH2 will not be passed to the molecular oxygen. Oxidation of NADH and FADH2 is required to continue glycolysis and Kreb's cycle. Therefore, in the absence of cytochrome oxidase, the cells will perform anaerobic respiration to oxidize NADH into NAD+ so that glycolysis can be continued as a source of energy.
Answer:
The lower pressure balloon will expand. Figure 2 (above left) shows a typical initial configuration: the smaller balloon has the higher pressure. So, when the valve is opened, the smaller balloon pushes air into the larger balloon. It becomes smaller, and the larger balloon becomes larger.
Hope this is helps out
Explanation:
Answer:
Viruses have the characteristic to multiply when they enter a living cell. But, they actually cannot reproduce.
The answer is two, haploid.
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so each of these two haploid cells will in meiosis II produce two haploid cells. In total, meiosis results in four haploid cells.
