Figure 16.3
Above is a metabolic pathway for the synthesis of an amino acid E), without which an organism could not live. Enzymes are represented by numbers, and substrates by letters. Use this figure for the next questions.
-Refer to the figure above. If an organism is given E in their diet, they survive. However, if the same organism is given only substrate A, B, C, or D in their diet, they die. Which of the enzymes is most likely defective?
A) Enzyme 1
B) Enzyme 2
C) Enzyme 3
D) Enzyme 4
