Why can we say that having a pure non- competitive inhibitor present is similar to just having less enzyme present?

22.

In a Lineweaver-Burk plot of an enzyme inhibited with a competitive inhibitor, how does the plot change with increasing inhibitor concentration? a) the slope decreases and the y-intercept stays the same b) the slope increases and the y-intercept stays the same c) the slope decreases and the y-intercept increases d) the slope increases and the y-intercept descreases e) none of the above

Which of the following are characteristics of catabolic metabolic pathways? (Choose all correct answers). Overall oxidation of initial substrates so redox reactions involve use of NAD+ as oxidizing agent, converted to NADH. Large initial substrates are broken down to smaller final products. Overall reduction of intial substrates so redox reactions involve use of NADPH as reducing agent, converted to NADP+. The pathways are overall exergonic (negative delta G). Net production of ATP as a result of the pathway. Essentially irreversible
