Answer:
Speeding up chemical reactions by lowering the activation energy.
Explanation:
Things going from low concentration to high concentration with ATP. An example would be the sodium potassium pump
Answer: I thought I have answered this question before. Yes emzymes are sensitive to PH and temperature.
Explanation:
if the temperature is above 60 - 70 degree celcius, it looses it's ability to catalyse as such emzymes are kept within the normal body temperature to function effectively. Emzymes are also sensitive to PH changing the pH of its surroundings will also change the shape of the active site of an enzyme and also changing the pH will affect the charges on the amino acid molecules.
Answer:
the correct oprtion is B
Explanation:
the correct answer is b, since increasing the porosity of the contact lens allows it to work as a good method of gas exchange, simulating the lung membranes that present fenestrated capillaries that promote gas exchange. For this to happen, the permeability must always be high and therefore this is directly related to the porosity of the element with which the contact lens is made.
