Question

Imagine a biochemistry lab is testing out a new procedure to improve the synthesis of a dipeptide molecule made with the amino acids Valine and Threonine. The hypothesis is that acid as a catalyst will improve the condensation reaction between the amino acids and create a greater yield of a dipeptide (molecule formed with these two amino acids). The procedure compares the result of 10 samples using the common older procedure (A) to ten samples using the newer acid synthesis procedure (B). They run an experiment : The standard reaction without using acid catalyst yields an average of 0.65 grams per reaction. The new acid catalyst reaction produces an average of 1.05 grams per experiment. Note: You do not need to know how much the quantities used in the experiment; you just need to understand the result below. The scientists run a t-test to compare the outcomes. They find that the p-value is p=0.01. The structure of the amino acids are below Valine Threonine HH HO 'c-c-N HOCH H ,N-Ç-c H,C' CH, H CH OH но сн,

Answer 1

A. Reaction without acid is the control group while reaction work the acid is the experimental group. B. Dependent variable is the acid catalyst whereas independent variables are the amino acids.. c. Yes. Because the yield of the dipeptide is increased by 1.6 fold in presence of acid. C- 1 он CH a 't HO Ho 'cha i H "-e-e-N-ere OH CN, HO CH E.
