Answer:
Stomach Flu
Explanation:
Stomach flu—or gastroenteritis—is an infection of the stomach and upper part of the small intestine. Common symptoms are diarrhea, vomiting, stomach pain, and cramps. Rotavirus and norovirus, which affect millions of people every year, are often the cause. Gastroenteritis often clears up on its own, but you lose fluids through diarrhea and vomiting. Prevent dehydration by drinking water and electrolyte drinks.
Answer:
The exergonic reaction of hydrolysis of ATP must be coupled to an endergonic reaction to perform work or to power other reactions.
Explanation:
ATP (adenosin triphosphate) is hydrolized to give ADP and releases energy as follows:
ATP + H₂O ⇆ ADP + Pi + energy
The released energy itself is not used to power biochemical reaction. In order to power other reactions, ATP hydrolysis- a energetically favorable reaction- is coupled to another energetically disfavorable reaction. The linking or coupling is performed through a shared intermediate, which is often a phosphorilated molecule. For example, in the formation reaction of sucrose from glucose and fructose, an intermediate is formated by the transfer of a phosphate group (Pi) provided by ATP hydrolysis. Then, the phosphorilated intermediate (glucose-Pi)- wich is unstable- reacts with fructose in a spontaneous reaction to give sucrose.
Answer:
Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
