Why is the catalytic activity of enzymes essential to ensure and regulate cellular metabolism? correct answer: enzymes lower the activation energy for chemical rxn. Why are microorganisms able to cause diary products, such as milk, to sour or curdle? correct answer: microorganisms can break down the nutrients in the milk and cause it to sour or curdle. Give a reason why it is necessary for polysaccharides, such as starch or cellulose, to be digested outside of the cell even though di-sac...
