After all this info you have given me, the correct one is Keystone species. As defined in sources like National Geographic, <span> These are types of plants or animals that play a unique and crucial role in the way an ecosystem functions. Without </span>keystone species<span>, the ecosystem would be dramatically different or cease to exist altogether. I hope this helps you a lot </span>
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.
Creo que sería D: Procariotas y eucariotas. Desafortunadamente, no es you 100% segura. Si no es D, entonces tal vez A: Unicelulares y pluricelulares.
Answer: A.Minerals are the basic building blocks from which nearly all rocks are made.
The Election Transport Chain
