Lysosomes contain hydrolytic enzymes that derive from the endoplasmic reticulum (ER) and work best under a pH that is different from cytoplasmic pH. These enzymes, called lysozymes, use this low pH to degrade damaged macromolecules, but they are able to spare their own protein and enzyme contents. Which of the following conditions is likely to cause a buildup of materials in the lysosome?

inhibiting the protein synthesis in the ER
decreasing the supply of amino acids to the cell by half
providing the cell with more nutrients so that more protein can be made
having a mutation in a lysosomal proteinase that renders it more resistant to self-digestion

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
