My test says citric acid cycle, acetyl coA and pyruvate
Amino Acids are absorbed into circulation after the complete digestion of proteins.
For an amino acid to become glucose, it must enter through the different members of the Kreb's Cycle. The first reaction is to remove the amino group of the amino acid before entering the cycle. There are 5 amino acids that enter through; pyruvate: alanine, cysteine, glycine, serine and threonine alpha ketoglutarate: glutamate, glutamine, arginine, histidine, proline oxaloacetate: aspartic acid and asparagine fumarate: phenylalanine and tyrosine succinyl coA: isoleucine, methionine, valine
Amino acids are too polar and too big to diffuse through the highly impermeable phospholipid bilayer. A special transport system must be set up to allow them to enter the cell.
Protein molecules are composed of amino acids, which contain nitrogen and sometimes sulphur. Your body uses amino acids to produce new proteins and to replace damaged proteins. Your body can synthesize most of the 21 amino acids that you need to make protein, with the exception of nine essential amino acids (histadine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine) that must come from your food. Fortunately, all unrefined foods have varying amounts of protein with varying amino acid profiles, including leafy green vegetables, tubers, grains, legumes, and nuts. All the essential and nonessential amino acids are present in these foods in amounts that meet or exceed your needs.
They are molecules with low weights.Their surface charge must be very low. Water,some amino acids, some other chemicals enter this way
Proteins are made of molecules called amino acids. When proteins enter the Body, they are broken up into amino acids that are more easily absorbed by the Body.
When you eat foods with proteins, your body breaks down the proteins into amino acids, then combines those amino acids to make the proteins it needs. Meat products tend to have more amino acids, so are naturally more beneficial to your body. Some substitutes are possible, except they do not always have the amino acids you need.
Amino acids, mono-sugars, fatty acids, glycerol, minerals and vitamins enter the blood stream. They enter from the portal venous system. You get amino acids from the protein digestion. You get mono-sugars from the carbohydrate digestion. You get the fatty acids and glycerol from the digestion of the fats. Vitamins and minerals need no digestion, before absorption.
amino acid molecules are water soluble meaning they cannot enter the cell. Fatty acid molecules CAN enter the cell.

large molecules and charged molecules move across a cell membrane through "facilitated diffusion." That is to say, a transport protein in the plasma membrane of the cell is used (with the aid of adenosine triphosphate, or ATP) to move the substance from one side of the membrane to the other.This method is actually the basis upon which all cell function is based, from generating and using energy, to keeping the cell isotonic to its environment.
A ribosome is a part of a cell that makes different kinds of protein, using amino acids and RNA. A focal point of biology is the fact that DNA is used to make RNA, which in turn is used to make proteins. The DNA sequence in a gene is copied into a mRNA (the 'm' stands for 'messenger'). A ribosome will then read the information in this RNA and use it to create various proteins. The process explained above is known as translation, as the ribosome 'translates' the genetic information given by the RNA into proteins. Ribosomes do this by attaching to an mRNA and using it as a template to make the correct sequence of acids for a particular protein. The amino acids are attached to tRNA molecules (the 't' stands for 'transfer'), which enter the ribosome and attach the acids to the sequence of mRNA. The attached amino acids are then joined together by another part of the ribosome. The ribosome moves along the mRNA, 'reading' the sequence of amino acids, and then producing a chain.
Proteins are too large to pass through the cell membrane. Therefore proteins need to be broken down in order to enter a cell. These amino acids can then be recycled, and new proteins made.
