"IV" stimulates synthesis of "T" by raising the Km of an enzyme for its substrate, "III". b. "1" stimulates synthesis of "IV" by lowering the Km of an enzyme for its substrate, "Il". c. "V" stimulates synthesis of "T" by raising the Km of an enzyme for its substrate, "III". d. "V" stimulates synthesis of T by lowering the Km of an enzyme for its substrate, "III". e. "I stimulates synthesis of "IV" by raising the Km of an enzyme for its substrate, "ll".

Answer 1

22. Option E is correct.

Explanation: Substrate 'I' stimulates the synthesis of substrate 'IV' by raising the Michaelis-Menten constant (K_M) of an enzyme for its substrate 'II' because substrate 'II' and substrate 'IV' are structurally similar.
