Extracted text: 4. Using the figure to the right, explain the similarities and differences between the two types of passive transport that are shown. Passive transport Diffusion Facilitated diffusion 5. Renin is an enzyme produced by the kidneys that plays an important role in helping to control blood pressure. Normal blood pH is just above 7, and around the neutral pH range of 7 renin works best. Explain what might happen to the enzyme if the pH in blood changes so much that it does not match the enzyme's optimal range where it functions best. Underscore the severity of this problem beyond the enzyme itself, thinking about the overall health. Part #3 Data Analysis Enzymes are biological catalysts, which means they speed up chemical reactions by lowering the activation energy without being used up. Look at the graphs to the right and explain why the shapes of the graphs are 1. different. Make sure to use the term 'saturation leveľ in your answer. Enzyme concentration (b) Substrate concentration (a) Reaction rate Reaction rate
