What is LIPID
When substrates bind to enzymes, they form a _____ ______.
What is an ENZYME-SUBSTRATE COMPLEX.
What does it mean that water is a polar molecule?
Water molecules are polar due to uneven distribution of electrons, with the oxygen side being slightly negative and the hydrogen sides being slightly positive.
