The sugar molecule lactose is found in milk products and must be broken down to be properly digested. People who are lactose intolerant do not naturally produce the enzyme lactase. What role does this enzyme play? A) Enzymes act as structural components (parts) of the cell
B) Enzymes catalyze chemical reactions to break down the lactose molecules
C) Enzymes slow down chemical reactions to break down the lactose molecules
D) Enzymes act as long term energy storage molecules and provide energy to the organism when broken down

At stp, what is the volume of 1 mole of co2?

In which phase(s) do the molecules take the shape of the container?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
