What is the difference between a lizards digestive enzyme along the two gastrointestinal tracts form a human?

Lizards have a simpler digestive system compared to humans, which is reflected in their digestive enzymes. Lizards primarily rely on enzymes like amylase and proteases that are efficient for breaking down their specific diets, which can include insects, plants, and small animals. In contrast, humans have a more complex gastrointestinal tract with a wider variety of enzymes, including lipases and lactases, to digest a broader range of foods, such as carbohydrates, fats, and proteins. This difference allows each species to effectively process their respective diets.
