Different combinations of amino acids give different properties to proteins. Therefore, the main feature that should be used in distinguishing proteins from each other is the amino acid sequence of proteins. However, proteins can be distinguished by their size and the biochemical properties as well.
Answer:
d) passage of a solute against its concentration gradient
Explanation:
When a solute is transported against its concentration gradient, the cells use metabolic energy. To move a substance from the region of its lower concentration to that of its higher concentration, the energy of ATP hydrolysis is utilized. These types of transport mechanisms are called active transports. If ATP hydrolysis is inhibited in a cell, it would not be able to perform the uphill movement of solutes due to the lack of any source of energy to drive the process.
In humeral fractures, the main nerves in the arm may have been damaged or compressed (by the cast) after manual reduction. The sensory nerve involved in this case is the musculocutaneous nerve which provide sensation in the hands, particularly here in the right hand. Compression by the cast interrupts nerve impulses in the musculocutaneous nerve owing to the loss of sensation and the removal of cast relieves the compression therefore there is regain of sensation.
ATP is a high-energy molecule found in every cell. Its job is to store and supply the cell with needed energy. hope this helps :)
