Phospholipids and sterols are very important for human diet.

  • Phospholipids are molecules connected to fat that include phosphorus, fatty acids, and a base that contains nitrogen.
  • They have a glycerol backbone similar to triglycerides, but instead of three fatty acids, it is joined to two fatty acids and a phosphorus group.
  • Phospholipids are crucial molecules since they make up a crucial part of cell membranes. They support the flexibility and lack of rigidity of organelle and cell membranes. 
  • As the majority of a cell's membrane, phospholipids are crucial for cells.
  • Sterols have a distinctive four-ring structure with carbon and hydrogen atoms as its main building blocks.
  • The most well-known sterol is cholesterol, which is essential for cell membrane formation and the building block of many significant chemicals in the body.

nikdorinn [45]

A lion and a leopard  have almost  the  same characteristics  in terms  of feeding habitat and behavior. because the lion rules the wild. The lion is the forest's king, and he is feared by every animal that lives there. Additionally, lions hunt other large or small animals in packs.

Leopards and lions differ significantly in terms of their physical characteristics, size, and socialization. The majority of lion species have manes, and they are exceptionally huge quadrupedal cats that live in groups called prides. Leopards lack manes, are more solitary than lions, have spotted fur, and are smaller than lions.

The hybrid offspring of a male leopard and a female lion is known as a leopon. The animal resembles lions in the head, whereas leopards are more likened to in the rest of the body. These hybrids are created in facilities; they are not expected to appear naturally. The Leopard's greatest foe is undoubtedly the Lion, with whom it will engage in a fight to the death. Leopards, especially the young cubs, have been known to be attacked and killed by baboons and hyenas.

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.
