Enzymes
Many people know enzymes help with digestion, but few realize enzyme production decreases with age, making it more difficult for bodies to digest certain foods. A worksheet offers 28 fill-in-the-blank and short-answer questions over...
Curated OER
Metabolism & Enzymes
More extensive than just a general overview of digestion and reactions, this slide show gives information about all areas of enzyme function. Topics like the chemistry behind efficiency of enzymes, factors that affect speed of reaction,...
