Question
Answer me fast please I appreciate it no explanation is needed following statements is TRUE about enzyme catalysts? ey lower the activation energy for conversion of substrate to product be effective, they must be present at the same concentration as their substrate hey can change the reaction from thermodynamically unfavourable to spontaneous heir catalytic activity does not depend on p he following is true in regards to Kct kan can be determined only if the concentration of enzyme [E] is known. kcat is referred to as the turnover number. According to Michaelis-Menton kinetics, k determines the affinity of the substrate to the a and b a and c haelis constant, Km, is equal to The maximum velocity that any given enzyme reaction can achieve The substrate concentration which gives the best enzyme assay for an enzyme reaction The substrate concentration when the reaction is half way toward the maximum velocity The maximum velocity divided by half s an enzyme's Km compare to its affinity for substrate? The greater the Km, the higher the affinity The lower the Km, the higher the affinity Km can describe the enzyme's affinity only if the inhibitor is not present. The relationship depends on the enzyme's Vmax. elis-Menten plot of the enzyme activity (reaction rate vs substrate concentration), the curve reaches a plateau and does not increase any further upon adding more substrate i here is a competitive inhibitor present ere is a non-competitive inhibitor present e active site is saturated with substrate substrate has been converted to product itor attaches to the site different from the active site of the enzyme and affects both te affinity. What type of inhibitor is this? petitiveExplanation / Answer
Ans 1 A) They lower the activation energy for conversion of substrate to product.
The enzymes are called as the biological catalysts of our body. They lower the activation energy barrier of the reaction , so that more number of substrate molecules can cross this barrier and get converted into products. This way they increase the rate of reactions , without themselves getting consumed in it.
