Aliun [14]

Answer:

Sympathetic nervous system

Explanation:

The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.

There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.

what is meant by an atp cycle and why is it an important frequent event in cells? how does this involve adp
strojnjashka [21]

Answer:

Please find the explanation to this question below

Explanation:

The ATP cycle is the series of reactions involving glycolysis, Krebs cycle and oxidative phosphorylation that produces/synthesizes ATP in living cells. These processes collectively is called CELLULAR RESPIRATION. Glycolysis produces 2ATP molecules, Krebs cycle produces 2ATP while the electron transport chain (oxidative phosphorylation) produces 34ATP molecules.

This cycle of ATP as explained above is an important frequent event in cells because all organisms need energy to carry out their metabolic activities. ATP is the energy-carrying molecule that stores and releases energy for use by the cells, hence, it needs to be produced on a frequent basis.

ATP can be likened to a charged battery ready to release its stored energy. The energy is stored in the phosphate bonds that makes up its structure. When ATP releases its energy, it becomes ADP (Adenosine diphosphate). However, ADP is a reactant in the ATP cycle, which is phosphorylated with an inorganic phosphate (Pi) and catalyzes by ATP synthase to form ATP.
