PFK can be allosterically inhibited by ATP at high concentrations. Which of the following is the benefit of regulating glycolysi
melamori03 [73]

Answer:

The principle benefit of regulating glycolysis by the concentration of ATP is to signals the cell to stop glycolysis as sufficient amount of ATP is already present in the biological system.

Explanation:

Phosphofructokinase 1 is allosterically inhibited by ATP.Glycolysis is a catabolic as well as exergonic process which deals with the oxidation of glucose to form pyruvate along with ATP molecules.

            When ATP is present at high concentration within our body at that time there is no need to synthesize additional ATP because ATP is already present in sufficient amount.

       To maintain its own homeostasis ATP allosterically inhibit the catalytic activity of phosphofructokinase. As a result glycolysis is inhibited and the glucose molecule can be utilized in other metabolic pathways.

According to biochemist sidney fox, once amino acids formed in the oceans, they may have collected in small pools to form small
Blizzard [7]

Formed tiny polypeptides known as Proteinoids when they gathered in little pools.

<h3>What is a polypeptide and how does it work?</h3>

Polypeptides. By joining many amino acids together, polypeptides contribute to the creation of proteins. When two or more polypeptides are joined together to form a protein, the resulting structure is unique to that protein.

<h3>What conclusions did Sidney Fox's experiment reach?</h3>

In the 1950s, Sidney Fox demonstrated that when amino acids were splashed in hot, dry circumstances, they immediately polymerized into proteins. Other studies that used cyanide, clays, and heat to cause the polymerization of amino acids into proteins were effective.

Transparent, translucent, and opaque are the three categories of materials that has a relation with transmitted light. Transparent objects are those from which the light passes through e.g plastic, water etc while on the other hand, translucent objects are those from which some of the light pass through e.g sunglasses and wax paper etc and opaque objects are those from which no light can pass through their body e.g wood and metal etc.

Which of the cell types shown helps determine capillary permeability?
alexira [117]

The correct answer to this is:

“Astrocytes”

Astrocytes also called star cells due to their shape are the most abundant glial cells in the brain. Extensions from these cells encase capillaries and offer extra control over which materials enter or leave the intercellular fluid of the CNS thus acting like a permeability membrane.
