What is substrate-level phosphorylation?
Lunna [17]

Answer:

D --  ATP synthesis when the phosphate donor is a substrate with high phosphoryl transfer potential

Explanation:

Substrate- level phosphorylation is the synthesis of ATP from ADP by the transfer of phosphoryl group from a substrate with high phosphoryl group potential to the ADP molecule.

In substrate-level phosphorylation, the donor is a phosphorylated intermediate molecule with a high phosphate transfer potential and it is a way through which phosphate in introduced into a molecule, the other two ways are oxidative phosphorylation and photophosphorylation. In substrate-level phosphorylation, a PO4^2- is transferred from a phosphate intermediate (substrate) to ADP to form ATP. Phosphorylase and kinases are enzymes involved in this reaction. An example is the reaction in glycolysis which involves phosphoenolpyruvate and ADP to form Pyruvate and ATP. This is to ensure adequate supply of energy to cells and also during anoxia so as not to make mitochodria strain the glycolytic ATP reserves.

Which of the following are characteristics of archaeal cell membranes that probably help them survive at very high temperatures?
torisob [31]

Answer:

Option-B, C and E

Explanation:

Archaebacteria are a group of prokaryotes which can survive the extreme conditions. The archaebacteria which can survive very high temperature are called hyperthermophiles. The hyperthermophilic bacteria can survive temperature range between 70 t 125 °C observed in hydrothermal vents.

The archaea bacteria can withstand the high temperature as their membrane is adaptive. The membrane of the archaea is more stable due to the ether linkage which makes carbon less chemically reactive. The phospholipids possess a monolayer which decreases the layer fluidity and thus the unwanted movement of molecules.

The archaea also contain cyclopentane rings in the ester-linked phospholipids which allows tight pacing of the molecules which decrease the movement of solute into and out of the cell.

Thus, the selected options are correct.
