Because all enzymes are specific in nature therefore the must fit to their specific substrates so if the shape is changed it might not fit perfectly to it's substrate.
The answer is C. Ribosomes
I hope that helped
Answer:
1) The protein is a tetramer, i.e., it has 4 subunits
2) The protein has two identical subunits with a molecular weight of 90 kDa
3) Because this protein contains two subunits with identical molecular weight (90 + 90= 180)
Explanation:
160 kDa + 90 kDa + 60 kDa = 310 kDa >>
Subunit X = 400 kDa - 310 kDa = 90 kDa >> Two subunits with a weight of 90 kDa likely linked by disulfide bonds (i.e., non-reducing conditions can break all bonds except sulfide interactions)
