Which statement BEST explains why enzymes bind to specific substrates? An enzyme can be inhibited so its active site is altered An enzyme folds differently in the presence of different substrates Different amino acid sequences cause variations in the shapes of an enzyme's active sites Enzyme-substrate binding is based on size so only large enzymes can bind to large substrates
