zhenek [66]
I cannot find the list of molecules and organs, but I gonna explain all existing lipid digestion.
First, you should know that triglycerides are not absorbable. The absorbable substances are free fatty acids, monoglycerides and cholesterol.

The main stages of lipid digestion:-Fat emulsification;
-Hydrolysis of lipids (by enzymes);
-Formation of micelles;
-Endocytosis of the micellar contents.

The enzymes responsible for lipid hydrolysis are:
lipases (pancreatic): secreted by the exocrine pancreas
colipase: secreted by the pancreas in an inactive form. Its role is to help the lipase in its activity.
cholesterol esterase: secreted by the pancreas too.
phospholipase A2: exists in the majority of the cells

Why lactic acid fermentation is considered a type of Anaerobic respiration, when both of them are different things.
zepelin [54]

Answer:

Lactic acid fermentation is a type of anaerobic respiration

(or fermentation) that breaks down sugars to produce

energy in the form of ATP. It is called anaerobic because it

occurs in the absence of oxygen . Lactic acid is generated

as a byproduct of this reaction, which is what gives this

type of fermentation its name.

and also Lactic acid fermentation is the type of anaerobic

respiration carried out by yogurt bacteria (Lactobacillus

and others)
