Which metabolic pathway requires a proton gradient?

Biology

Ad libitum [116K]2 years ago

Oxidative phosphorylation requires a proton gradient.

  • Cells use enzymes to oxidize foods in the metabolic pathway known as oxidative phosphorylation, electron transport-linked phosphorylation, or terminal oxidation, which releases chemical energy to create adenosine triphosphate.
  • This happens inside mitochondria in eukaryotes. The majority of the energy required for biosynthesis, maintaining a healthy ion balance, and mechanical effort is provided by oxidative phosphorylation, which is the principal source of ATP in higher animals.
  • A succession of proteins and electron carriers in the mitochondrial membrane, as well as the electron transport chain, are all involved in the process of oxidative phosphorylation.

List three types of evidence for seafloor spreading

<span>Molten material found in the bottom of seafloors indicated underwater eruptions that formed new areas of the seafloor was presented as evidence for seafloor spreading. Due to earths magnetic polarity and its tendency to switch, iron present on the sea floor contained a magnetic record of sea floor expansion progress. Finally, drilling samples obtained in the seafloor indicated the deeper samples of were significantly older than the shallower samples that were brought up.</span>

The correct options are as follows:
1. D.
Natural selection refers to the process by which living organisms that are more  adapted to their environments usually survive and produce offspring that are like them. In the case of giraffes, the giraffes with the longest necks were able to survive in their environment and they reproduce offspring that are like them.
2. D
In the scientific world, scientists have open minds and they welcome all new ideas. These new ideas have to be tested to ensure that they are correct and superior to the facts that are already known. When a new hypothesis is put forward by a scientist, many scientists all over the world will test the hypothesis is order t confirm if it correct. If the hypothesis is found to be correct it will be accepted by all scientists.
3. A.
DNA test is a laboratory analysis that can be used to assess the level of relationship between living organisms. Related living organisms usually have some similar genes in their DNA, the level of closeness of these organisms will determine the quantity of similar genes that will be found in their DNA. Unrelated organisms on the other hand will have little or no similar genes in their DNA.
4. C.
The genetic code is the same across species, this fact points to the possibility that all living organisms originated from common ancestors. This support the evolution theory which stated that all living organisms descended from a common ancestor.
5. B.
Antibiotic drugs are usually effective against bacteria and other microbes, but the microbes can evolve and develop resistance to these drugs. Microbes are considered to have evolved when drugs that are used to inactivate them before no longer have any effect on them, thus they can easily survive in the presence of the drugs.
6. B.
If a particular specie of animal is able to avoid predators, it will increase in number more that those that are prey on by predators. The kings snakes were probably able to avoid predators, that is why, they were able to survive, reproduce offspring and increase in population in that particular ecosystem.

Turgor pressure is the pressure exerted on a plant cell wall by water. When wilted plants are placed in water, they demonstrate
Rus_ich [418]

Answer: When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.

Explanation:

Turgor is a phenomenon in plant cells in which the cell expands due to the pressure exerted by the fluids and also by the cell content on the walls. It is related to osmosis, since the external pressure is usually very high and this internal pressure dilates the cell as much as the elasticity of the membranes allows. <u>Then, the cells swell by absorbing water, tensing the membranes because of the pressure against them.</u> When the fluid exerts outward pressure on the cell wall it is called turgor pressure.  Whereas, the inward pressure exerted on the cell contents by the stretched cell wall is called wall pressure. Generally, both pressures, turgor pressure and wall pressure, are counterbalanced and balanced.

So, this pressure of turgor facilitates the elongation of the cells in the plant, and also, the cells use this phenomenon to regulate the transpiration through the opening and closing of the stomach.

Thereby, the turgor of a living cell is influenced by three primary factors:

  • An adequate supply of water.
  • The formation of osmotically substances.
  • A semi-permeable membrane.

Vacuoles are organelles bounded by a single membrane and present in plant and fungal cells, and where water is stored. Plant cells control their turgor pressure through the movement of water into or out of vacuoles. When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
