Digestion :)
cell wall
the molecules required by our body in small quantity is kown as macro molecules
A polymer is a long chain of small molecules (monomers).
Most molecules can move in and out of a cell, but different molecules have different methods of getting in- Small Non-Polar molecules can diffuse across the lipid bilayer Medium sized molecules of any kind require a specific protein channel HUGE MOLECULES require a process called endo and exocytosis
These substances are called enzymes.
mastication i think....i know that is at least the first part of the process that takes place in your moth.......i think its the whole thing..
digestion
into your small intestine.
cellular respiration
Nutrient molecules pass from the small intestine into the through tiny structures called villi.
Mechanical digestion. The actual grinding and physical breaking down of food. Chemical digestion breaks down food using chemicals/enyzyms and chemical reactions.
No
Yes.
Digestion
The two processes that occur are digestion and absorption. Digestion is the process by which your body breaks down food into small nutrient chemicals. While absorption is the process in which when the small nutrient molecules go through a wall of the digestive system and into the blood.
The process of breaking down food so we can absorb it is called digestion. Releasing the energy by breaking it down further in our cells is respiration.
It is broken down into small molecules by a complicated process called digestion. Digestive enzymes like saliva, gastric juice, intestinal juice, bile, pancreatic juice all play a part in digesting and breaking down the food to small molecules so that it can get absorbed by the small intestine
