Question
Recall what happens in physical digestion.A chemical reaction takes placeNo new substances are producedAn enzyme converts one chemical into anotherFood is not broken into smaller pieces but just mixed
Solution
Physical digestion refers to the process where food is broken down into smaller pieces, primarily through the mechanical processes of chewing (in the mouth) and churning (in the stomach). No chemical reactions take place in physical digestion, and no new substances are produced. It's not about converting one chemical into another, which is a process that happens in chemical digestion, not physical digestion. So, the food is indeed broken into smaller pieces and mixed, but not chemically altered.

Your body has two main ways of breaking down food to release nutrients:physical digestion – slicing, grinding, mashing and churning to break substances into smaller pieces and mix them togetherchemical digestion – using chemical reactions to convert substances into simpler chemicals that can be more easily absorbed by the bodyThe key difference is that in chemical digestion, new substances are produced. Substances that speed up chemical digestion are called enzymes. The video mentions that these are produced by bacteria in the large intestine, but some of our own organs produce them too.Question 12SavedRecall what happens in physical digestion.A chemical reaction takes placeNo new substances are producedAn enzyme converts one chemical into anotherFood is not broken into smaller pieces but just mixedI'm not sureQuestion 13SavedVenus flytraps produce enzymes to break down the bodies of the insects they catch.Determine which type of digestion this is.PhysicalChemicalI'm not sure
