Animals with bilateral symmetry have a distinct head end
Answer:During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
Explanation:
They use energy from the breakdown of a molecule called ATP. ATP is often called the energy currency of our body as it is used all around in the human body for different processes that need energy - so not just active transport of proteins. ATP gets broken down into ADP and an extra group of P (phosphates).
Answer: The fight-or-flight response is most clearly associated with the release of epinephrine into the bloodstream.
Any physiological reaction occurring due to something which frightens physically or mentally is fight-or-flight response. In order to produce the fight-or-flight response the hypothalamus activation of the adrenal cortical system and sympathetic nervous system takes place. On receiving the signal from hypothalamus the sympathetic nervous system makes the actions of body speed up or gets tensed and body is in an alert condition.
The impulses are sent by the sympathetic nervous system to the smooth muscles and also glands. As a response to it epinephrine or adrenaline and the norepinephrine or noradrenaline is released by the adrenal medulla in the bloodstream. These stress hormones thus bring about changes in the body such as increase in blood pressure and heart rate.
Then it is a cancer cell. Cancer cells divide without restrainments ( free for all), attacking the body, and killing organisms. :)
