What is it called when a string of islands that forms where two convergent boundaries collide?

Biology

7 0

When two convergent boundaries collide, especially in the ocean, an Island arc is formed.

When these  two convergent plates collide, the older plate which is denser subducts beneath the younger plate.  As the subducting plate is pushed deeper into the mantle, it melts. The magma this creates rises and erupts. This forms a line of volcanoes known as an island arc , with considerable earth quakes created.

Examples of island arcs include Japan, Indonesia, the Phillipine Islands and the Aleutian Islands  of Alaska.

How many atp are made in the electron transport part of cellular respiration
Dmitry [639]

Answer:

34

Explanation:

The electron transport chain of cellular respiration includes oxidation of NADH and FADH2. The electrons from these reducing powers are passed to the terminal electron acceptor via electron transport chain. During the transfer of electron via electron transport chain, the generated electrochemical gradient drives ATP synthesis.

The net yield of NADH from glycolysis and Kreb's cycle is 2 and 6 per glucose molecule respectively. In addition, decarboxylation of pyruvate also obtains 2 NADH per glucose. Kreb's cycle forms 2 FADH2 molecules during reduction reactions. In total, 10 NADH and 2 FADH2 are formed which then enter the electron transport chain and drive ATP synthesis.

One molecule of NADH generates the electrochemical gradient enough to drive the synthesis of 3 molecules of ATP while each FADH2 obtains 2 ATP molecules. Therefore, total 10 x 3 = 30 ATP molecules from oxidation of NADH and 2 x 2 = 4 ATP from oxidation of FADH2 are obtained.

LiRa [457]

Cytotoxic T cells are rapid killers of infected target cells. Within minutes of the interaction of a cytotoxic T cell with a target cell, the program of apoptosis in the target cell is initiated. This rapid activity is a consequence of The extremely rapid production of granzymes and perforin by cytotoxic effector cells upon encountering a target cell.

  • A type of T cell known as a cytotoxic T cell (CD8+ T cell) is in charge of removing things that the immune system recognizes as dangerous.
  • Cytotoxic T cells are essential for controlling bacterial growth and illnesses in the body.
  • By instructing their targets to undergo apoptosis, cytotoxic T lymphocytes kill their prey.
  • Cytotoxic T cells can instruct antigen-specific target cells to die within 5 minutes of coming into contact with them when they are mixed with target cells and quickly brought into contact by centrifugation.
  • The speed with which cytotoxic T cells can induce apoptosis in their targets is due to the release of prepared effector molecules that trigger the target cell's own endogenous apoptotic pathway.
