Cholestrol streghtens the cell memebrane. Its STRUCTURE gets fixed in the cell membrane and then performs its FUNCTIONS that is to strengthen the cell membrane
Brodt and Zimbardo found that shy women who were bombarded with loud noise and told that it would leave them with a pounding heart were subsequently no longer so shy when interacting with a handsome male.
a) with a pounding heart; no longer so shy
<u>Explanation:</u>
Shy is an emotion expressing nervousness, being reserved and timidity when communicating or being with some people. Shyness is generally observed in the person who has low self-confidence and inferiority complex.
Brodt and Zimbardo found that when a woman is continuously allowed to face loud noise, initially it may lead to pounding heart and subsequently they get used to it and they will be no longer shy. These scientists also found that when woman is interacting with the handsome male they will never feel shy.
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.
