Simple diffusion and facilitated diffusion both allow molecules to cross the cell membrane without any expenditure of energy by the cell. They are each classified as a type of passive transport.
Answer:
Concentration = 0.011 M
Explanation:
Molarity is given by dividing number of moles by volume in Liters
Molarity = moles/volume
But;
Number of moles = mass/molar mass
= 10 g/ 74.55 g/mole
= 0.134 moles
Therefore;
Molarity = 0.134 moles/12 L
= 0.011 M
Catalysts lower the Activation energy for reactions. The lower the activation energy for a reaction,the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrate ms bind.
