Question & Answer
Choose the Best Answer
Sample preparation is unnecessary when using spectrophotometry for protein measurement.
Proper sample preparation can increase the accuracy of spectrophotometric measurements by removing interfering substances.
Sample preparation is only relevant for qualitative analysis and not for quantitative spectrophotometry.
All proteins can be measured directly without any form of sample preparation.
Understanding the Answer
Let's break down why this is correct
When you clean a sample, you remove things that can hide or change the light signal. Other options are incorrect because Some think you can skip cleaning, but leftover salts or dyes still affect the light; Quantitative tests need exact numbers, not just a yes or no.
