Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An enzyme’s active site that loses it proper shape is considered
A
An enzyme-substrate complex
B
Denatured
C
Both a and b
D
Neither a nor b
Explanation: 

Detailed explanation-1: -The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens). A substrate enters the active site of the enzyme. This forms the enzyme-substrate complex.

Detailed explanation-2: -If the enzyme changes shape, the active site may no longer bind to the appropriate substrate and the rate of reaction will decrease. Dramatic changes to the temperature and pH will eventually cause enzymes to denature.

Detailed explanation-3: -What is an enzyme-substrate complex? The enzyme-substrate complex definition is a temporary molecule formed when the substrate binds to the enzyme. When an enzyme binds to its substrate, it undergoes a conformational change or temporary change in shape.

Detailed explanation-4: -A denatured enzyme refers to an enzyme that has lost its normal three-dimensional, or tertiary, structure.
