QUESTION 7 Consider the biochemical pathway A+E1 --> B+E2 --> C, where A, B, and Care substrates and products and E1 and E2 are the enzymes that catalyze the reactions. Enzyme 1 (E1) can utilize only B as substrate. O only A as substrate. both A and B as substrates either A or B as substrate, but not both. neither A nor B as substrate.

1. You are considering the following biological reactions that are catalyzed by specific enzymes as shown below. In reaction #1, enzyme El catalyzes the conversion of compound A to compound B in a truly reversible reaction in which the reverse reaction is just as likely as the forward reaction. In reaction #3, enzyme E2 catalyzes an energy requiring reaction that uses compounds C and D as substrates to produce compound E. In reaction #3, enzyme E3 catalyzes an energy producing...

QUESTION 1 Imagine you want to get rich by genetically engineering tobacco plants to produce acai berry juice. To do so, you insert the genes for each of the enzymes in the hypothetical acai synthesis pathway, the first step of which is (hypothetically) conversion of glucose to fructose. The challenge is that glucose must be maintained at or above a minimum concentration or the plant will die because it can no longer make ATP. For the reaction pathway shown below,...
