there are 3 different ways that misfiled or unused proteins can be recycled into individual amino acids for use in building new proteins.In what ways is this recycling of oddly shaped and nonfunctional proteins important to the human survival. How would life be different if such a recycling did not take place? Find a research article on the topic of misfiled proteins and disease caused by them. Answer in a short paragraph or two explaining. (I'm having a hard time understanding the topic if you can break it down for me would be so helpful) I couldn't find any articles that made sense for me to write a paragraph explaining.

Based on the known mechanism of the enzyme glyceraldehyde-3-phosphate dehydrogenase predict the outcome of the following situations or reactions. Include a brief justification of your answer for each case. See p 519 of the text for the mechanism – Figure 14.7. Things to consider in answering this question: The acetyl phosphate experiment:NAD+ Glyceraldehyde 3-phosphate ÇH20P03 NAD+ HCOH H Glyceraldehyde 3-phosphate dehydrogenase Cys Cys Formation of enzyme-subsfollow the expected making and breaking of the bonds and what you know about the mechanism.

Predict what would happen if acetyl phosphate (a mixed anhydride of acetic and phosphoric acids) is used as the enzyme substrate in the presence of 32P inorganic phosphate. Hint: A catalyst catalyzes are reaction equally in the forward and in the reverse direction.
