What processes drive motion of the plates?

2 answers:

5 0

Earth's crust are pushing against each other miles below the Earth's surface, causing earthquakes, volcanoes and the movement of the continents. Approximately 30 plates are mapped out throughout the world. The plates consist of the Earth's crust and of the mantle, which is a thick layer of hot rock. Below that lies a sea of magma.

Hope this helps

Ridge push or sliding plate force is a proposed driving force for plate motion in plate tectonics that occurs at mid-ocean ridges as the result of the rigid lithosphere sliding down the hot, raised asthenosphere below mid-ocean ridges.The name comes from earlier models of plate tectonics in which ridge push was primarily ascribed to upwelling magma at mid-ocean ridges pushing or wedging the plates apart.

Usually, the best practices would dictate that a guest account would be placed in a secure network, isolated from the production network by firewall barriers. If it is impractical, then specific areas of access should be determined and they should be as restrictive as possible.

Describe the adaptations of the mammalian kidney to selective reabsorption<br><br>

Anvisha [2.4K]

Answer: The tubule is long and highly coiled to provide a large surface area for selective reabsorption. The coiling of the tubule reduces the speed of the flow of the filtrate to give more time for efficient reabsorption. The tubule is well supplied with blood capillaries to increase a steep diffusion gradient for selective re-absorption.

Explanation: Selective reabsorption occurs because during ultrafiltration, important components of the blood are filtered out and they need to be reabsorbed into the body.

If ethyl alcohol contains almost as much energy as the original pyruvic acid, what can you infer about the efficiency of ferment

shusha [124]

Explanation:

Fermentation has a comparatively low efficiency as it produces the same amount of energy, whereas aerobic respiration produces up to 38 molecules of ATP .

Aerobic respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Within cells, aerobic respiration may not occur due to several factors:

- a lack of inorganic, final electron acceptors
-incomplete or lack of a complete electron transport system
-missing genes for enzymes within the Kreb's cycle

Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation.

Net production of ATP in fermentation: 2 ATP
Net production of ATP in aerobic respiration ≈38 ATP

Further Explanation:

overall in aerobic respiration: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
