Enzymes are crucial contributors to protein digestion. Protein-digestingproteinases or proteases. Protein generally takes the form of very complex molecules arranged in chains of amino acids. So the bonds binding these complex molecules together must first be broken down.
enzymes are referred to as
This digestive process begins in the stomach, where hydrochloric acid, secreted in the stomach's gastric acid, attacks the protein molecules separating them and breaking them down into amino acids. Then the gastric enzyme pepsin - the only protease able to digest collagen starts to digest the amino acids.
Digestion of proteins continues in the first segment of the small intestine. As in fat digestion, the pancreas helps the process by secreting the pancreatic protease enzymes trypsin and chymotrypsin. Like pepsin, trypsin breaks down a protein into single amino acid molecules, through a process called hydrolysis. During hydrolysis, a water molecule is inserted between the two amino acids which are bonded together. This breaks the bond between them.
After breakdown, the amino acids are small enough to pass through capillaries in the villi. Once in the bloodstream, the amino acids are distributed by both red blood cells and by the liquid blood plasma to tissues throughout the body where they are used in the creation and repair of cell structures. Such is the demand for protein, the body maintains a constant balance of amino acids in the blood.
I hope that helps! Other than that I have no idea!!
What else can I help you with?
What happens to a molecule off protein during digestion?
During digestion, proteins are broken down into their individual amino acids by enzymes in the stomach and small intestine. These amino acids are then absorbed into the bloodstream and used by the body for various functions such as building muscle, repairing tissues, and supporting immune function.
When protein compounds are catalyzed what do they do to the chemical reaction during digestion?
Neutralize chemical reactions during digestion
How is protein converted during digestion?
converted by pepsin.
Where does a tRNA bind to an mRNA molecule during the process of protein synthesis?
A tRNA binds to an mRNA molecule at the ribosome during the process of protein synthesis.
What macro-molecule is produced during translation?
protein
What happens in the stomach during the digestion?
what orgens resposible for digestion
During what process is the anticodon-containing molecule used?
The anticodon-containing molecule is used during the process of translation in protein synthesis.
What could be used as a substrate when testing for the digestion of protein to peptides?
Gelatin or casein can be used as substrates for testing protein digestion to peptides. Gelatin is a denatured form of collagen, while casein is a milk protein. Both substrates can be broken down by proteolytic enzymes into smaller peptides during digestion experiments.
During digestion what molecule enters the cell?
The goal of digestion is to break down food to the glucose level. Only then will it be absorbed into the cell and be used in respiration.
What molecule is broken down into amino acids?
Proteins are broken down into amino acids through the process of digestion in the body. Proteins are made up of long chains of amino acids linked together. Once proteins are broken down during digestion, the individual amino acids are absorbed and used by the body for various functions.
What happens to the molecule of protein during digestion?
During digestion, proteins are broken down into smaller peptides and amino acids by enzymes in the stomach and small intestine. The stomach's acidic environment activates pepsin, while pancreatic enzymes like trypsin and chymotrypsin further degrade proteins into smaller chains and individual amino acids. These amino acids are then absorbed through the intestinal lining into the bloodstream, where they are transported to cells for various functions, such as building new proteins and supporting metabolism.
What assists the metabolization of protein?
Enzymes in the body help to metabolize protein. The process occurs during digestion and as the food flows through the intestines.
