Question

Succinate is the substrate for succinate dehydrogenase that converts succinate to fumarate. In the presence of reversible competitive inhibitor like malonate in place of succinate, the enzyme's
(A) Km increases and Vmax remains same max
(B) Both Km and Vmax increases
(C) Both Km and Vmax decreases
(D) Km decreases and Vmax remains the same​

Answer 1

b both km and vmax increase

Answer 2

In the reversible competitive inhibitor, the enzyme's $Km_{}$ increases and $Vmax_{}$ remains the same.

Explanation:

• Option d is the answer of this question

• Inhibition of succinate dehydrogenase by malonate is example of competitive inhibition.

• Competitive are the inhibitor that fight with substrate for the site of enzyme.
• Many inhibitor resemble the shape of enzyme and combine with site of enzyme and form complex
• Competitive Inhibition can be studied by steady-state kinetics
• Enzyme Inhibitor hinder the way of catalysis.
