Answer 1

Explanation:

are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream

Emulsification is the process of breaking down the fat into smaller blood cells which makes it easy for enzymes to function and digest food. Fat emulsification helps digest fats into fatty acids and glycerol that are easily absorbed by the small intestine. What is the difference between emulsification and digestion?

yruvate is converted to acetaldehyde and then to ethanol in alcoholic fermentation.
