Question

question 1 (1 point)

1. denaturation is a process by which the weak bonds that collectively maintain the native shape of the apoenzyme are broken.

o a) true
o b) false
question 2 (1 point)
intermittent sterilization is also called tyndallization
o a) true
o b) false
question 3 (1 point)
autoclaving is effective for most materials except for
o a) proteins
o b) enzymes
o c) amino acids
o d) oils

Explanation:

• Question 1: Denaturation is indeed the process where weak bonds (like hydrogen bonds, ionic bonds etc.) that maintain the native (natural) shape of proteins (apoenzyme is a protein part of an enzyme) are broken.
• Question 2: Intermittent sterilization is also known as tyndallization. It involves a series of heating and cooling cycles to kill spores.
• Question 3: Autoclaving uses high - pressure steam. Oils are not effectively sterilized by autoclaving because they do not allow proper penetration of steam. Proteins, enzymes (which are proteins), and amino acids can be autoclaved (though proteins and enzymes may denature, but the goal of autoclaving is sterilization, not preserving their activity in some cases).

Answer:

• Question 1: A. True
• Question 2: A. True
• Question 3: D. oils
