The breakdown of food via enzymatic reactions is known as __________.
r-ruslan [8.4K]
I believe you're looking for "chemical digestion".

Chemical digestions is where food that we ate is digested into simpler and soluble molecules that can be absorbed by our body. Enzymes are used as a catalyst to speed up the reaction.

One example is the digestion of lipids. Enzyme named lipase is used to speed up the digestion of lipids into 3 fatty acid molecules and 1 glycerol. This way, our body can absorb these simple molecules, and use them in order to make our body function.

On the other hand, physical digestion does not include enzymes, such as chewing in our mouth, therefore, don't mix them up!

Lina20 [59]

It is virtually impossible to locate the genetic factors involved in most psychological characteristics because of <u>polygenic inheritance</u>.

Multiple genes, or polygenes, generate features in polygenic inheritance. Numerous diverse phenotypes, or displayed qualities, may be expressed through polygenic traits. When phenotypes were expressed, a variety of inherited qualities are mixed together due to polygenic inheritance, a kind of incomplete dominant inheritance.

The phenotypic, such as the color of one's hair or skin, is produced by polygenes working together. Polygenic traits don't inherit in the same ways as Mendelian traits do. Multifactorial traits will be many polygenic qualities that have been additionally influenced through the environment.
