Predict the effect of a large amount of acetyl-coa on the activity of pyruvate dehydrogenase and the rate of glycolysis. note: pyruvate dehydrogenase is the enzyme that catalyzes the formation of acetyl-coa from pyruvate. a. pyruvate dehydrogenase activity will decrease while the rate of glycolysis will increase. b. both pyruvate dehydrogenase activity and the rate of glycolysis will decrease. c. pyruvate dehydrogenase activity will increase while the rate of glycolysis will decrease. d. the rate of glycolysis will increase, thereby, leading to an increase in pyruvate dehydrogenase activity.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o

Rate law for this reaction israte of the reaction = k[a]²[b].second order in a  means concentration of a in power of two, and  first order in b means concentration of b in power of one.
