Plants and trees use photosynthesis
Answer:
Substances that are altered by the action of proteases are known as: 1) substrates.
Explanation:
Protease is an enzyme, therefore a substrate would have to fit the enzyme, which forms an enzyme-substrate complex. This causes a chemical reaction since enzymes are biological catalysts. Many enzymes often change their shape so that the substrate can fit at the active site.
I hope this makes sense!! ^-^
Answer:
Explanation:
A protease is an enzyme that catalyzes the hydrolysis of the peptide bonds that tie polypeptide chains together, releasing individual amino acid subunits. The L and D nomenclature for amino acids defines the structure of the glyceraldehyde isomer through which the amino acid can be produced.
SEE BELOW FOR THE APPROPRIATE STRUCTURES.
We need to figure out why swine proteases hydrolyze L-amino acids but not D-amino acids in any way. we know that enzymatic catalysts act as polypeptides if you can recall. They must retain a very precise three-dimensional structure for a catalytic activity to occur. Substrates that do not quite match the required configuration at the active site will not be reacted to — this is a "lock and key" style.
The present exercise may be explained by the fact that the configuration and structure of D-amino acids prevent them from binding properly to the active site of the protease enzyme. Perhaps they're pointed in the wrong direction, or perhaps there happens to be missing electrical interaction that's needed to keep the substrate in position.
Nonetheless, L-amino acids, on the other hand, seem to have the right configurational aspects in the active site and are hydrolyzed.
Answer:
THE BLOOD CELLS FLOWING THROUGH THEM WOULD NOT BE ABLE TO EXCHANGE GAS WITH THE SURROUNDING TISSUE
THE BLOOD CELLS WOULD FLOW SLOWLY THROUGH THEM, PREVENTING THEM FROM CARRYING OXYGEN TO TISSUE
THE BLOOD CELLS FLOWING THROUGH THEM WOULD FORM CLOTS ALONG THEIR WALLS THAT BLOCK FLOW TO TISSUE.
Explanation:
Capillaries are connecting vessels that connects the arteries and veins. They are only two-celled thick vessels and allows the exchange of ions, solutes and other essential nutrients except plasma proteins which are large proteins and cannot undergo simple diffusion into cells. The type of circulation in capillaries is called micro-circulation.Capillaries pick up oxygen in the blood to the tissues and carbon dioxide to be eliminated from the tissues. So if the capillary walls are thicker than normal, it functions disappears. It probably becomes an artery or a vein. Gaseous exchange with the surrounding tissue is affected, nutrients carriage is impaired and blood cells can not flow through them in a single file as the case in normal capillaries with two cell layer thickness. Blood cells will therefore flow slowly through them and this affect the delivering of oxygen to tissues. Also, because of the inability of the blood cells to flow properly, blood clots could bee formed along the walls of the capillaries and hinder blood flow to the tissue.
